CVE-2004-2062

Vulnerability

AntiBoard versions 0.7.2 and earlier are vulnerable to SQL injection in the antiboard.php script. The thread_id, parent_id, and mode parameters are not properly sanitized before being used in SQL queries, allowing an attacker to inject arbitrary SQL statements. This issue is documented in a Bugtraq post [2].

Exploitation

An attacker can exploit this vulnerability by sending a crafted HTTP request to the vulnerable antiboard.php script with malicious SQL code in any of the three parameters (thread_id, parent_id, or mode). No authentication is required, and the attack can be performed remotely over the network. The attacker simply needs to manipulate the parameter values to break out of the intended SQL syntax and execute arbitrary commands.

Impact

Successful exploitation allows the attacker to execute arbitrary SQL queries against the database backend (MySQL or PostgreSQL). This can lead to unauthorized reading, modification, or deletion of data, including user credentials and private messages. In some cases, the attacker may be able to escalate privileges or gain administrative access to the bulletin board.

Mitigation

No official patch was released for this vulnerability. Users of AntiBoard 0.7.2 or earlier should upgrade to a newer version if available, or apply input sanitization and parameterized queries to the affected parameters. As the software is likely end-of-life, migrating to an alternative bulletin board system is recommended.
