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.
