Doubles has discovered a vulnerability in Unzoo, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an input validation error when unpacking archives. This can be exploited via a directory traversal attack to overwrite files outside the directory, where the files are extracted to, if a user is tricked into extracting a malicious archive using Unzoo.
The vulnerability has been confirmed on version 4.4.2. Other versions may also be affected.
