Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of the interface. 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. To exploit these vulnerabilities, the attacker must have valid administrative credentials.
The severity of this vulnerability is classified as medium with a CVSS score of 4.8. Organizations using affected versions of Cisco ISE should be aware of the potential impact, as this vulnerability allows attackers to execute scripts that may compromise sensitive information.
Risk to organizations includes unauthorized access to user data and the execution of harmful scripts, leading to further exploitation. Organizations should prioritize patching immediately.
Currently, no public exploit is confirmed, and the vulnerability is not listed in the Known Exploited Vulnerabilities (KEV) catalog, but the potential for exploitation remains.
Vulnerability Details
The vulnerabilities in Cisco ISE's web-based management interface are classified under CWE-79, which pertains to improper neutralization of input during web page generation. The affected versions include all versions prior to 3.2 and select versions of 3.2.x and 3.3.x. The publication date of the advisory was February 5, 2025.
Technical Analysis
The root cause of the vulnerabilities stems from insufficient input validation, allowing attackers to inject malicious scripts in the web management interface. The attack vector is network-based, with low complexity involved in crafting the attack due to the requirement for high privileges and user interaction.
Risk & Impact Analysis
The real-world risk includes potential unauthorized access to sensitive information and the execution of malicious scripts that could compromise user data. The vulnerability has a moderate blast radius, particularly in environments where Cisco ISE is critical for managing network access and identity services. Organizations should address in priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The following versions of Cisco Identity Services Engine are affected: all versions prior to 3.2, and specific patches of 3.2.0, 3.3.0, and 3.4.0.
Mitigation & Remediation
Organizations should upgrade to the latest version of Cisco Identity Services Engine to remediate this vulnerability effectively. For systems where immediate patching is not feasible, consider implementing configuration hardening and access controls to limit administrative access. Continuous monitoring for unusual activities is also recommended. More information can be found in the penetration testing services.
Detection Guidance
Monitor logs for indicators of unauthorized access attempts. Pay attention to behavioral anomalies and network signatures that could indicate exploitation attempts. Additionally, observe system changes that coincide with user interactions with the web management interface.
