Title: MyBB Private.PHP Multiple SQL Injection Vulnerabilities

Severity: MODERATE

Description:

MyBB is a bulletin-board application implemented in PHP using a MySQL backend.

MyBB is prone to multiple SQL-injection vulnerabilities. The application fails to properly sanitize user-supplied input.

The vulnerabilities present themselves when user-supplied input via the 'folder' and 'check' variables is passed to the 'private.php' script, permitting remote attackers to pass malicious input to database queries, resulting in the modification of query logic or other attacks.

Successful exploitation can allow an attacker to bypass authentication and gain administrative access to a site, modify data, or exploit vulnerabilities in the underlying database implementation.

MyBB version 1.0.3 is reported to be vulnerable.

Affected Products:

  • MyBulletinBoard MyBulletinBoard 1.0.3
