Detailsinfo

A vulnerability was found in Cisco Identity Services Engine Software and ISE Passive Identity Connector (affected version not known). It has been rated as problematic. Affected by this issue is some unknown functionality of the component Web-based Management Interface. The manipulation with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. Impacted is integrity. CVE summarizes:

A vulnerability in the web-based management interface of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to conduct a stored XSS attack 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 the affected device.

The advisory is shared for download at sec.cloudapps.cisco.com. This vulnerability is handled as CVE-2025-20331 since 10/10/2024. The exploitation is known to be easy.
