A vulnerability in the web framework of Cisco Secure Access Control System (ACS) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web interface on the affected system. The vulnerability is due to insufficient input validation of a parameter. An attacker could exploit this vulnerability by convincing a user to access a malicious link. Cisco has confirmed the vulnerability in a security notice and released software updates. 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. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
