• → Monitor HTTP GET/POST requests to delete_img.php containing directory traversal sequences ('../' or './') in the 'img' parameter. ↗
• → Alert on requests to delete_img.php where the 'img' parameter references paths outside the intended uploads directory, indicating arbitrary file deletion attempts. ↗
• → Correlate delete_img.php traversal attempts with prior file upload activity, as the exploit is most impactful when chained with a file upload vulnerability. ↗

• · The vulnerable parameter is 'img' in delete_img.php; ensure WAF or input validation rules specifically target this parameter for path traversal patterns. ↗
