Description

FreePBX is an open source IP PBX. Prior to 16.0.22 and 17.0.5, the Dashboard module's getcontent AJAX handler includes PHP files based on user-supplied input without path sanitization. The $_REQUEST['rawname'] parameter is concatenated into an include() call with a .class.php suffix, allowing path traversal via ../ sequences to include arbitrary .class.php files from the filesystem. The included file's PHP code executes before the subsequent class instantiation error occurs. This vulnerability is fixed in 16.0.22 and 17.0.5.
