Joomla 1.5 com_virtuemart <= 1.1.7 Blind time-based SQL Injection (MSF)
[# Exploit Title: Joomla 1.5 com_virtuemart <= 1.1.7 blind time-based sql injection MSF module

'Name' => 'Joomla 1.5 VirtueMart Component <= 1.1.7 Blind SQL Injection',
'Description' => %q{
A vulnerability was discovered by Rocco Calvi and Steve Seeley which identifies
unauthenticated time-based blind SQL injection in the "page" variable of the
virtuemart component. This vulnerability allows an attacker to gain information
from the database with specially crafted URLs taking advantage of the MySQL
benchmark. This issue was patched in version 1.1.7a.
