Abstract:
=========
The Vulnerability Laboratory Core Research Team discovered a critical SQL Injection vulnerability in the Avira Analysis 
online service application.

Affected Products:
==================
Avira
Product: Analysis - Web Application & Online Service 2013 Q2


Exploitation-Technique:
=======================
Remote


Severity:
=========
Critical


Details:
========
A remote SQL Injection web vulnerability is detected in &#1616; 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.

Vulnerable Module(s):
                                [+] en

Vulnerable File(s):
                                [+] overview

Vulnerable Module(s):
                                [+] uniqueid


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.
