Cisco Web Security Appliance Web Tracking Report Page Cross-Site Scripting Vulnerability

A vulnerability in the Web Tracking Report page of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to perform a cross-site scripting (XSS) attack against the user of the web interface.

The vulnerability is due to improper validation of user-supplied input in a field on the Web Tracking Report page. An attacker could exploit this vulnerability by persuading a user to follow a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected site or allow the attacker to access sensitive browser-based information.

Cisco has confirmed the vulnerability; however, software updates are not available.

To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
