Title: phpBB Viewtopic.PHP SQL Injection Vulnerability

Severity: HIGH

Description:

phpBB is an open-source web forum application that is written in PHP and supported by a number of database products. It will run on most Unix and Linux variants, as well as Microsoft Windows operating systems.

A SQL injection vulnerability has been reported for phpBB systems that may result in the disclosure of user password hashes; other attacks may also be possible.

phpBB, in some cases, does not sufficiently sanitize user-supplied input, which is used when constructing SQL queries to execute on the underlying database. As a result, it is possible to manipulate SQL queries. This may allow a remote attacker to modify query logic or potentially corrupt the database.

This vulnerability was reported to exist in the viewtopic.php script file. A remote attacker can exploit this vulnerability by manipulating the $topic_id URI parameter to modify SQL query logic.

SQL injection attacks may also potentially be used to exploit latent vulnerabilities in the underlying database implementation.

Affected Products:

  • phpBB Group phpBB 2.0.4
  • phpBB Group phpBB 2.0.5
