A vulnerability in the Virtual Keyboard Video Monitor (vKVM) connection handling of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker with low privileges to conduct a stored cross-site scripting (XSS) attack against a user of the interface. This vulnerability arises from insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit this by injecting malicious code into a specific data field, potentially executing arbitrary script code or accessing sensitive information.
Details
| Severity | Base Score | CVE |
|---|---|---|
| MEDIUM | 5.4 | CVE-2025-20342 |
Exploitation
To exploit this vulnerability, an attacker must have valid user credentials that grant them access to the vKVM feature on the affected device. By injecting malicious code into a specific data field within the web-based management interface, the attacker can execute arbitrary scripts in the context of the interface, potentially compromising sensitive information.
Affected Products
- Cisco Integrated Management Controller (IMC) – Affected by the vKVM vulnerability, allowing for potential XSS attacks.
- Cisco UCS Manager – Includes the affected vKVM client, making it susceptible to the same vulnerabilities.
Mitigation
To mitigate this vulnerability, it is recommended that users ensure proper input validation and sanitization within the web-based management interface. Additionally, restricting access to the vKVM feature to only trusted users and regularly updating the system can help reduce the risk of exploitation.
