Details:
========
A high severity File Include vulnerability is detected on the Cyberoam UTM Appliance CR300i 10.01.2.
The vulnerability allows an local low privileged user account to request local system or application files
(example:telnet-service jsp). Successful exploitation can result in dbms or service/appliance compromise
via file include vulnerability. The vulnerability is located on the WWWHELP &file= value request which
allows the privileged attacker to implement a local appliance path to request in a context frame the system files.
