FlightPath 4.x and 5.0-x allows directory traversal and Local File Inclusion through the form_include parameter in an index.php?q=system-handle-form-submit POST request because of an include_once in system_handle_form_submit in modules/system/system.module.

  • Look for POST requests to index.php?q=system-handle-form-submit containing the 'form_include' parameter with directory traversal sequences (e.g., '../').
  • Exploitation requires a valid form_token, which the attacker first retrieves via a GET /login request (even with invalid credentials). Monitor for rapid GET /login followed by POST to system-handle-form-submit.
  • The vulnerable parameter is 'form_include' in the POST body, processed by include_once in system_handle_form_submit inside modules/system/system.module. Alert on any non-empty form_include value containing path traversal characters.
  • Successful exploitation of LFI to read /etc/passwd will produce a response body matching the pattern 'root:.*:0:0:'. Use this as a response-based detection signature.
  • ·The exploit requires a two-step process: first obtain a valid form_token via GET /login, then use it in the malicious POST. Detection rules must account for this token-harvesting pre-step.
  • ·The vulnerability affects FlightPath versions prior to 4.8.2 and 5.0-rc2 only. Scope detection rules to these version ranges.
