• → The vulnerable upload endpoint is includes/doajaxfileupload.php — monitor for unauthenticated POST requests to this script containing multipart file uploads with executable extensions (e.g., .php). ↗
• → Webshell execution occurs via direct GET requests to files dropped under /wp-content/plugins/mm-forms-community/upload/temp/ — alert on any GET to this directory path, especially for .php files. ↗
• → Use Google dork 'inurl:/wp-content/plugins/mm-forms-community/' to identify exposed vulnerable WordPress installations for proactive scanning. ↗

• · The two Snort/Suricata rules (SID 2015726 and 2015727) only detect GET requests to the upload/temp directory (webshell access stage), not the initial file upload POST to doajaxfileupload.php. Additional rules covering the upload phase are needed for full coverage.
• · Affected versions are strictly 2.2.5 and 2.2.6 of the MM Forms Community WordPress plugin; detections should be scoped accordingly to reduce false positives on patched or unrelated installations. ↗
