Cisco Prime Access Registrar Stored Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Prime Access Registrar could allow an authenticated, remote attacker to perform a stored cross-site scripting attack on an affected system.

This vulnerability exists because the web-based management interface does not sufficiently validate user-supplied input. 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 would need valid administrative credentials.

Cisco expects to release software updates that address this vulnerability. There are no workarounds that address this vulnerability.
