Description
Summary
In `torrentpier/library/includes/functions.php`, `get_tracks()` uses the unsafe native PHP serialization format to deserialize user-controlled cookies:

PoC
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`.
