[~]>> TITLE: Joomla Module (Customers_who_bought...) SQL Injection Vulnerability
[~]>> LANGUAGE: PHP
[~]>> DORK: N/A
[~]>> RESEARCHER: B-HUNT3|2
[~]>> CONTACT: bhunt3r[at_no_spam]gmail[dot_no_spam]com
[~]>> TYPE: COMMERCIAL
[~]>> PRICE: 14,95€
[~]>> TESTED ON: Demo Site


!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[~]>> DESCRIPTION: Test done against Customers_who_bought (VirtueMart Module) and sh404SEF Joomla component
[~]>> Both Commercial Joomla extensions, so my researching is poor. Injection is done in url redirection
[~]>> (View SQL errors) and result can be visible in source code, url, error page,...
[~]>> Since sh404SEF is used I cann't detect affected vars, but also there are BSQLi.
[~]>> Trying to search the module/component vulnerable, i've tested sh404SEF and VirtueMart. But Vulnerability
[~]>> cann't reproduce. Probably issue is in Customers_who_bought Module (hence advisory title).
[~]>> AFFECTED VERSIONS: Confirmed in 1.1 stable but probably other versions also
[~]>> RISK: Medium/High
[~]>> IMPACT: Execute Arbitrary SQL queries
