Advisory Details:

High-Tech Bridge Security Research Lab discovered multiple vulnerabilities in 
Elite Bulletin Board, which can be exploited to perform SQL injection attacks.


1) Multiple SQL injection vulnerabilities in Elite Bulletin Board: CVE-2012-5874

The vulnerabilities exist due to insufficient sanitation of user-supplied data 
in URI in the "update_whosonline_reg()" and "update_whosonline_guest()" 
functions within the "/includes/user_function.php" script. 

A remote attacker can send a specially crafted HTTP request to one of the 
following scripts and execute arbitrary SQL commands in application's database: 
- checkuser.php
- groups.php
- index.php
- login.php
- quicklogin.php
- register.php
- Search.php
- viewboard.php 
- viewtopic.php

Successful exploitation of the vulnerabilities may allow attacker to extract 
sensitive data from the application's database, and even get complete control 
over the application under certain conditions (such as insecure configuration 
of database and web servers).

The following PoC (Proof of Concept) codes demonstrate the vulnerabilities by 
displaying version of the MySQL server:
