Finding 1: Unauthenticated Backdoor Access
Credit: Chaim Sanders of Trustwave SpiderLabs

The default configuration of the Unanet web application has a backdoor that can 
allow unauthenticated users to login and manipulate the user accounts and the 
roles they maintain. This vulnerability is due to a code branch that exists 
within the product. This code allows the product to maintain a hardcoded user 
that is unlisted in the users table of the database. 

The steps to reproduce the finding include the following:

1.	Navigate to a Unanet site.
2.	Open up a proxy such as Burp.
3.	Proxy the initial login page through Burp
4.	Add the ‘Cookie: unanetAccess=0%7CUNANET%7C__unanetAdministrator__%7C477c49a990eeabde873313578ce1daeb’ to the report
5.	Forward the request and you will be logged into the application as Unanet


Remediation Steps:
Fixes for this issue were released in Unanet versions 10.0.51, 10.1.43, and 10.2.5.
