HCL Compass is vulnerable to insecure password requirements. An attacker could easily guess the password and gain access to user accounts.

HCL Compass is vulnerable to failure to invalidate sessions. The application does not invalidate authenticated sessions when the log out functionality is called.  If the session identifier can be discovered, it could be replayed to the application and used to impersonate the user.

HCL Compass is vulnerable to lack of file upload security.  An attacker could upload files containing active code that can be executed by the server or by a user's web browser.
