• → Detect unauthenticated HTTP GET requests to /vtigercrm/libraries/ or /vtigercrm/layouts/ returning a directory listing response (HTTP 200 with 'Index of', 'vtigercrm', and 'Parent Directory' in the body).
• → Use Shodan or FOFA to identify exposed Vtiger CRM instances as potential targets: Shodan query 'http.html:"vtiger CRM"', FOFA query 'body="vtiger CRM"'.
• → Exploitation requires no authentication; any unauthenticated GET to the vulnerable paths is sufficient to trigger directory listing.

• · The vulnerability affects specifically Vtiger CRM v7.2.0; the /libraries and /layout directories are the affected paths per the CVE description. ↗
• · The nuclei template uses stop-at-first-match with max-request: 2, meaning detection probes both /vtigercrm/libraries/ and /vtigercrm/layouts/ but stops on the first positive match.
