Technical Details & Description:
================================
A classic auth bypass web vulnerability has been discovered in the official 
Classic Infomedia (Login) CMS (2016-Q1).
The web vulnerability allows to bypass the login mechanism that protects the 
web-application from unauthorized access.

index.php file. Remote attackers are able to inject 
own malicious strings to bypass the login authentification mechanism. The 
request method is POST and the attack vector of the 
issue is located on the application-side of the web-application. The 
vulnerability is a classic auth bypass vulnerability.

The security risk of the auth bypass vulnerability is estimated as critical 
with a cvss (common vulnerability scoring system) count of 9.1.
Exploitation of the remote login auth bypass web vulnerability requires no user 
interaction or privileged web-application user account.
Successful exploitation of the auth bypass vulnerability results in database 
management system, web-server and web-application compromise.
