Reported by: Nick Hayes

It is possible to re-use a link which includes a non-expiring  
authentication token in the query string to gain access to the interface  
of the Barracuda Web Application Firewall (WAF) firmware version 7.8.1.013.  
  
Example:  
  
http://waf.ptest.cudasvc.com/cgi-mod/index.cgi?auth_type=Local&et=99999999996locale=en_US&password=5a2fd48b65c5d80881eeb0f738bcc6dc&primary_tab=SECURITY%20POLICIES&secondary_tab=request_limits&user=guest  
  
The above link opens up the Request Limit Policies on the Barracuda labs  
WAF test host as the Guest user. This has been confirmed to work on  
actual devices and with administrative accounts.
