The Vulnerability Laboratory Research Team discovered multiple SQL Injection 
vulnerabilites in Simple Forum PHP v2.1 CMS.

Published


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

Severity:
=========
High


Details:
========
Multiple SQL Injection vulnerabilities  are detected in Simple Forum PHP v2.1 
Content Management System.
The vulnerability allows an attacker (remote) or local low privileged user 
account to inject/execute own sql commands 
on the affected application dbms without user inter action. Successful 
exploitation of the vulnerability results in 
dbms & application compromise. The vulnerabilities are located in the forum.php 
and admin.php files and bound parameters 
orderType, orderBy, & p. The vulnerability in forum.php can be exploited by 
remote attackers without required user 
inter action or privileged user account. A privileged user account is required 
to the exploit the sql bug in the admin.php.

Vulnerable File(s):
                                [+] forum.php
                                [+] admin.php

Vulnerable Parameter(s):
                                [+] orderType
                                [+] orderBy
                                [+] p


Proof of Concept:
=================
The sql injection vulnerabilities can be exploited by remote attacker with and 
without privileged user account.
