Details:
========
A remote SQL Injection web vulnerability is detected in ِ the official 
Avira Analysis online service application.
The vulnerability allows remote attackers to inject own sql commands to 
compromise the affected application dbms.

The SQL Injection vulnerability is located in the `overview` file when 
processing to request manipulated `uniqueid` parameter. 
By manipulation of the `uniqueid` parameter the attackers can inject own sql 
commands to compromise the webserver application dbms. 

When processing to bypass the filter validation by trying to use a single qoute 
or a double qoute to check if the parameter is vulnerable or not, 
attackers will be redirected to another page, but when the attacker is 
processing to request with a back-slash the context will be executed 
and new mysql errors will become visible for exploitation.

The vulnerability can be exploited by remote attackers without privileged 
application user account and without required user interaction. 
Successful exploitation of the sql injection vulnerability results in web 
application and online service dbms compromise.

Proof of Concept:
=================
The remote sql injection web vulnerability can be exploited by remote attackers 
without privileged application user account and without 
required user interaction. For demonstration or reproduce ...

Vulnerable Service Domain:      analysis.avira.com
Vulnerable Module:              en
Vulnerable File:                overview
Vulnerable Parameter:           uniqueid


Note: When trying to use a single qoute or a double qoute to check if the 
parameter is vulnerable or not, you will be redirected to another page, 
but when processing to load with a back-slash new mysql errors will become 
visible for exploitation.

Solution:
=========
The vulnerability can be patched by a restriction and secure parse of the 
uniqueid parameter request.


Risk:
=====
The security risk of the remote sql injection web vulnerability is estimated as 
critical.
