CVE-2023-4346 is a vulnerability in the KNX Association's KNX Protocol Connection Authorization Option 1, involving an overly restrictive account lockout mechanism. This flaw could allow an attacker to purge all devices that do not have additional security options enabled and set a BCU key to lock the device. The vulnerability has been exploited in the wild. No specific affected versions or patch information are provided.

Post-authentication improper control of generation of code ('Code Injection') vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) which in specific conditions could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands.

A Server-side request forgery (SSRF) vulnerability has been identified in the SMA1000 Appliance Work Place interface. A remote unauthenticated attacker could potentially cause the appliance to make requests to unintended location.

Weak authentication in Microsoft Office SharePoint allows an unauthorized attacker to bypass a security feature over a network.

Deserialization of untrusted data in Microsoft Office SharePoint allows an unauthorized attacker to execute code over a network.

Deserialization of untrusted data in Microsoft Office SharePoint allows an unauthorized attacker to execute code over a network.

Missing authentication for critical function in Microsoft Office SharePoint allows an unauthorized attacker to elevate privileges over a network.

Insufficient granularity of access control in Active Directory Federation Services (AD FS) allows an authorized attacker to elevate privileges locally.

Cisco IOS 12.4 contains multiple cross-site request forgery (CSRF) vulnerabilities that allow remote attackers to execute arbitrary commands by exploiting specific URIs related to privilege and configuration commands. These vulnerabilities enable unauthorized command execution via crafted HTTP requests targeting the device's web interface.

Between January and June 2026, multiple unrelated organizations experienced nearly identical intrusions following a standardized seven-step attack chain. The attacks exploited CitrixBleed 2 (CVE-2025-5777), a memory-overread vulnerability in NetScaler ADC and Gateway appliances. Attackers sent malformed pre-authentication login requests that leaked NetScaler memory containing valid session tokens, bypassing multi-factor authentication by hijacking active sessions. Following initial access, threat actors consistently escalated privileges to SYSTEM using a registry-symlink exploitation technique targeting the AppMgmt service, created rogue administrator accounts (CtxAppVCOMService, ctxsvc, test), and established persistence through legitimate remote access tools including ScreenConnect and Zoho Assist. The most advanced case culminated in DragonForce ransomware deployment. The highly standardized tradecraft, reused infrastructure, and consistent indicators across unrelated victims suggest a single Initial Ac...

Joomla Extension - balbooa.com - Unauthenticated file upload in Balbooa Forms extension < 2.4.1 - The Joomla extension Balbooa Forms is vulnerable to an unauthenticated arbitrary file upload that allows uploading executable files and leads to full RCE.

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.84.0, LiteLLM's MCP Streamable HTTP endpoint allowed an unauthenticated attacker to use a fabricated Authorization header to trigger an OAuth2 passthrough fallback path that replaced failed LiteLLM key validation with an empty UserAPIKeyAuth() object, allowing requests to reach MCP tooling without a valid LiteLLM key. This issue is fixed in version 1.84.0.

In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In __ip6_append_data(), when the paged-allocation branch is taken (MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen; datalen already includes fraggap (datalen = length + fraggap). When fraggap is non-zero, this is not the first skb and transhdrlen is zero. The fraggap bytes carried over from the previous skb are copied just past the fragment headers in the new skb's linear area. The linear area is therefore undersized by fraggap bytes while pagedlen is overstated by the same amount, and the copy writes past skb->end into the trailing skb_shared_info. An unprivileged user can trigger this via a UDPv6 socket using MSG_MORE together with MSG_SPLICE_PAGES. The bad accounting was introduced by commit 773ba4fe9104 ("ipv6: avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative copy value caused -EINVAL to be returned. That later commit allowed MSG_SPLICE_PAGES to proceed in this case, making the corruption triggerable. The non-paged branch sets alloclen to fraglen, which already accounts for fraggap because datalen does. Bring the paged branch in line by adding fraggap to alloclen and subtracting it from pagedlen. After this adjustment, copy no longer collapses to -fraggap on the paged path, so remove the stale comment describing that old arithmetic. Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES case, remove the MSG_SPLICE_PAGES exception from the negative copy check.

CISA says threat actors are exploiting a recently patched SharePoint remote code execution vulnerability (CVE-2026-45659). The post CISA Warns of Actively Exploited Microsoft SharePoint Vulnerability appeared first on SecurityWeek .

ColdFusion versions 2025.9, 2023.20 and earlier are affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.

Memory overflow vulnerability NetScaler ADC and NetScaler Gateway leading to unpredictable or erroneous behavior and Denial of Service if the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server
