Impact

An attacker with access to the Websense Content Gateway web interface or by tricking a logged in admin user to visit a specially crafted URL, a remote attacker can conduct a cross-site scripting attack, which could be used to result in information leakage, privilege escalation, and/or denial of service.

Solution

The vendor has reported that this vulnerability will be in addressed in version 7.7.3 which is scheduled to be released in December 2012.

Good security practices should be adopted to minimize the risk of compromise.
