Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Immediate application of Cisco's security patches or updates for all affected versions of Unified ICME is the most effective mitigation. Organizations should prioritize patching given the broad version impact. 2. Implement strict input validation and output encoding on the management interface to prevent injection of malicious scripts. 3. Restrict access to the web-based management interface to trusted networks and use VPNs or secure tunnels to reduce exposure to the internet. 4. Employ multi-factor authentication (MFA) for all users accessing the management interface to reduce the risk of compromised credentials. 5. Conduct user awareness training focused on phishing and social engineering to reduce the likelihood of users clicking malicious links. 6. Monitor web interface logs and network traffic for unusual activities indicative of exploitation attempts. 7. Use Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the browser context. 8. Segment the contact management infrastructure from other critical systems to contain potential breaches.

Description

A vulnerability in the web-based management interface of Cisco Unified Intelligent Contact Management Enterprise could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. This vulnerability is due to insufficient user input validation. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

Impact

For European organizations, the impact of this vulnerability can be substantial, especially for enterprises and service providers relying on Cisco Unified ICME for contact center management. Successful exploitation could allow attackers to steal session tokens, access sensitive configuration data, or manipulate the contact management system's interface, potentially disrupting customer service operations or enabling further attacks within the network. Given the critical role of contact centers in customer engagement and support, any compromise could lead to reputational damage, regulatory non-compliance (e.g., GDPR breaches if personal data is exposed), and operational downtime. Additionally, attackers could leverage this vulnerability as a foothold to escalate privileges or move laterally within the network. The requirement for user interaction (clicking a malicious link) means phishing campaigns targeting administrators or operators are a likely attack vector. The widespread use of Cisco products across Europe, including in regulated sectors like finance, healthcare, and telecommunications, amplifies the potential impact.
