Executive brief
TorrentPier, a BitTorrent tracker engine, contains a security flaw in its moderator control panel. An authorized moderator can exploit this vulnerability to gain unauthorized access to the underlying database. This could allow them to view sensitive user information, modify site data, or delete records, potentially leading to a full compromise of the forum's data.
Technical details
An authenticated SQL injection vulnerability exists in TorrentPier's moderator control panel (modcp.php). The root cause is the lack of sanitization or parameterization of the 't' (topic_id) GET parameter before it is concatenated into an SQL query string. An attacker with moderator-level privileges can inject malicious SQL syntax, such as time-based blind payloads, to bypass intended query logic. Successful exploitation allows for the disclosure of sensitive database information, modification of user records, or deletion of data. The vulnerability is patched in version 2.8.9.
