Multiple vulnerabilities have been reported in BlackBerry Enterprise Server, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose sensitive information, manipulate certain data, and cause a DoS (Denial of Service).

1) Input passed via the "displayErrorMessage" parameter to webdesktop/app (when "page" is set to "pages/advanced/ManageDevices" and "service" is set to "page") is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) Some vulnerabilities exist in the bundled Apache Tomcat server.
