Cisco Response

A vulnerability exists in Cisco TelePresence Video Communication Server (VCS) due to improper validation of user-controlled input to the web-based administrative interface. User-controlled input supplied to the login page via the HTTP User-Agent header is not properly sanitized for illegal or malicious content prior to being returned to the user in dynamically generated web content. A remote attacker could exploit this vulnerability to perform reflected cross-site scripting attacks.

Billy Hoffman from Zoompf, Inc., discovered this vulnerability and Ben Feinstein from Dell SecureWorks reported it to Cisco. Cisco greatly appreciates the opportunity to work with researchers on security vulnerabilities and welcome the opportunity to review and assist in product reports.

Additional Information
