BlackBerry UEM Management Console (BlackBerry Enterprise Server) Input Validation Flaw Lets Remote Authenticated Users Conduct Cross-Site Scripting Attacks
Severity Rating: High
Systems Affected:
  • BlackBerry UEM Management Console (BlackBerry Enterprise Server)
Description
A vulnerability has been identified in BlackBerry UEM Management Console (BlackBerry Enterprise Server) and can be exploited by remote attackers to conduct cross-site scripting attacks. The vulnerability exists because the software does not properly filter HTML code from user-supplied input before displaying the input. A remote authenticated user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the Management Console and will run in the security context of that site. As a result, the code will be able to access the target user's cookies if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
