path/wp-content/plugins/jsmol2wp/php/jsmol.php
  • Look for GET requests to jsmol.php containing 'php://filter/resource=' in the query parameter, indicating directory traversal / LFI exploitation attempts.
  • Monitor for the 'call=getRawDataFromDatabase' parameter in HTTP requests to jsmol.php, which is the specific endpoint abused for file read and SSRF.
  • Responses from successful exploitation will have Content-Type: text/plain header alongside HTTP 200 status.
  • ·The vulnerability affects JSmol2WP plugin version 1.07; version 1.08 and above are patched. Verify installed plugin version before triaging alerts.
  • ·The vulnerability can also be used for SSRF (Server-Side Request Forgery), not just local file read — detections should account for non-filesystem php://filter targets as well.
