Torrentpier

TorrentPier is an open source BitTorrent Public/Private tracker engine, written in php. In versions up to and including 2.8.8, an authenticated SQL injection vulnerability exists in the moderator control panel (`modcp.php`). Users with moderator permissions can exploit this vulnerability by supplying a malicious `topic_id` (`t`) parameter. This allows an authenticated moderator to execute arbitrary SQL queries, leading to the potential disclosure, modification, or deletion of any data in the database. Although it requires moderator privileges, it is still severe. A malicious or compromised moderator account can leverage this vulnerability to read, modify, or delete data. A patch is available at commit 6a0f6499d89fa5d6e2afa8ee53802a1ad11ece80.

TorrentPier is an open source BitTorrent Public/Private tracker engine, written in php. In `torrentpier/library/includes/functions.php`, `get_tracks()` uses the unsafe native PHP serialization format to deserialize user-controlled cookies. One can use phpggc and the chain Guzzle/FW1 to write PHP code to an arbitrary file, and execute commands on the system. For instance, the cookie bb_t will be deserialized when browsing to viewforum.php. This issue has been addressed in commit `ed37e6e52` which is expected to be included in release version 2.4.4. Users are advised to upgrade as soon as the new release is available. There are no known workarounds for this vulnerability.

Torrentpier version 2.4.1 allows executing arbitrary commands on the server. This is possible because the application is vulnerable to insecure deserialization.
