Cerberus Helpdesk before 4.0 (Build 600) allows remote attackers to obtain sensitive information via direct requests for "controllers ... that aren't standard helpdesk pages," possibly involving the (1) /display and (2) /kb URIs.

Cross-site scripting (XSS) vulnerability in includes/elements/spellcheck/spellwin.php in Cerberus Helpdesk 0.97.3, 2.0 through 2.7, 3.2.1, and 3.3 allows remote attackers to inject arbitrary web script or HTML via the js parameter. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information.

rpc.php in Cerberus Helpdesk 3.2.1 does not verify a client's privileges for a display_get_requesters operation, which allows remote attackers to bypass the GUI login and obtain sensitive information (ticket data) via a direct request.
