Technical details
An unsafe file inclusion vulnerability in the Superfecta module's AJAX handler (options and save_options cases) dynamically includes PHP files from the sources/ directory based on user input without proper validation. Exploitation requires authentication with a known username and combination with other modules' functionality (backup for directory creation, soundlang for path disclosure). Successful exploitation yields remote code execution as the web server user (asterisk or www-data), and patches exist in versions 16.0.40 and 17.0.7.
