CVE-2025-20204: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Cisco Cisco Identity Services Engine Software
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.
AI Analysis
Technical Summary
This vulnerability involves improper neutralization of input during web page generation in Cisco Identity Services Engine's management interface, enabling authenticated remote attackers to perform cross-site scripting attacks. Exploitation requires valid administrative credentials, and successful attacks could execute arbitrary script code in the context of the interface or expose sensitive browser information. The issue stems from insufficient input validation in the affected versions listed.
Potential Impact
An attacker with valid administrative credentials could exploit this vulnerability to execute arbitrary scripts within the web interface context or access sensitive information stored in the browser. This could lead to session hijacking or unauthorized actions within the management interface. However, exploitation requires authenticated access, limiting the attack surface. There is no indication of impact to system availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation is currently documented, users should monitor Cisco advisories for updates. Until a patch is available, restrict administrative access to trusted personnel and networks to reduce risk.
