Technical details

A reflected cross-site scripting (XSS) vulnerability exists in the BlackBerry WatchDox Server (Workspaces) Appliance-X (v1.8.1 and earlier) and vAPP (v4.6.0 through 5.4.1) components. The flaw is caused by improper neutralization of user-supplied input during web page generation. A remote, unauthenticated attacker can exploit this by persuading a user to follow a malicious link, resulting in the execution of arbitrary JavaScript in the context of the victim's browser session. This can be used to bypass same-origin policy protections, access cookies, or perform actions as the authenticated user.
