A vulnerability in the Cisco Secure Access Control Server (ACS) web interface could allow an unauthenticated, remote attacker to impact the integrity of the system by executing a Document Object Model (DOM)-based, environment or client side, cross-site scripting (XSS) attack. The vulnerability is due to a lack of input validation on user-supplied data within the DOM input. An attacker could exploit this vulnerability by sending crafted URLs that contain malicious DOM statements to the affected system. A successful exploit could allow the attacker to effect the integrity of the system via database manipulation. Cisco has not released software updates that address this vulnerability. Workarounds that mitigate this vulnerability are not available.
