This module exploits an unauthenticated SQL injection flaw in FreePBX prior to versions 15.0.66, 16.0.89,
and 17.0.3. The vulnerability lies in the /admin/ajax.php endpoint, which is accessible without
authentication. Additionally, the database user created by FreePBX can schedule cronjobs, allowing
remote code execution on the target system.
