Advisory Details:

High-Tech Bridge Security Research Lab discovered vulnerability in ImageCMS, 
which can be exploited to perform SQL injection attacks.


1)      SQL injection vulnerability in ImageCMS: CVE-2012-6290

The vulnerability exists due to insufficient filtration of the "q" HTTP GET 
parameter passed to "/admin/admin_search/". A remote authenticated 
administrator can execute arbitrary SQL commands in the application's database.

Depending on the database and system configuration PoC (Proof-of-Concept) code 
below will create "/tmp/file.txt" file with MySQL server version inside:


http://[host]/admin/admin_search?q=123%27%20UNION%20SELECT%201,2,version%28%29,4,5,6,7,8,9,10,11,1
 2,13,14,15%20INTO%20OUTFILE%27/tmp/file.txt%27%20--%202


This vulnerability can also be exploited by remote non-authenticated attacker 
via CSRF vector because the application is prone to Cross-Site Request Forgery 
attack. In order to do so attacker should trick a logged-in administrator to 
visit a web page with CSRF exploit. 

Basic CSRF exploit example:


<img 
src="http://[host]/admin/admin_search?q=123%27%20UNION%20SELECT%201,2,version%28%29,4,5,6,7,8,9,10,11,1
 2,13,14,15%20INTO%20OUTFILE%27/tmp/file.txt%27%20--%202">
