Description

A user with administrative privileges can abuse the problem_import_qduoj.php CGI script
using a crafted zip file (zip-slip) to traverse backwards through the filesystem, then to the
webroot, where they can extract a PHP file that spawns a shell to get full RCE in the
context of the webserver.
