affected by a session hijacking vulnerability due to the disclosure
of session IDs in the diagnostic.log file that can be accessed via
HTTP without authentication. An unauthenticated, remote attacker can
grab the log file and hijack active user sessions to perform
authenticated requests.  

Note that the product is reportedly affected by other
vulnerabilities; however, this plugin has not tested for them.");
