IDevSpot iSupport 1.8 - 'rightbar.php?suser' Cross-Site Scripting

source: https://www.securityfocus.com/bid/19963/info

IDevSpot iSupport is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user supplied data.

Exploiting these issues could allow an attacker to steal cookie-based authentication credentials and to launch other attacks.

Version 1.8 is vulnerable; other versions may also be affected.
