Cisco CSPC Web UI XSS via Input Validation Flaw
CVE-2025-20166 Published on January 8, 2025

Cisco Common Services Platform Collector Cross-Site Scripting Vulnerability
A vulnerability in the web-based management interface of Cisco Common Services Platform Collector (CSPC) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability 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 this vulnerability, the attacker must have at least a low-privileged account on an affected device. Cisco has not released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Weakness Type

Improper Neutralization of Invalid Characters in Identifiers in Web Pages

The software does not neutralize or incorrectly neutralizes invalid characters or byte sequences in the middle of tag names, URI schemes, and other identifiers. Some web browsers may remove these sequences, resulting in output that may have unintended control implications. For example, the software may attempt to remove a "javascript:" URI scheme, but a "java%00script:" URI may bypass this check and still be rendered as active javascript by some browsers, allowing XSS or other attacks.
