Technical description

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web interface of an affected system. The vulnerability is due to insufficient sanitization of user-supplied data that is written to log files and displayed in certain web pages of the web-based management interface of an affected device. An attacker could exploit this vulnerability by convincing a user of the interface to click a specific link or view an affected log file. The injected script code may be executed in the context of the web-based management interface or allow the attacker to access sensitive browser-based information.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
