  • Detect stored XSS via file upload to licenseUpload.php: monitor POST requests with multipart/form-data containing script tags (encoded or plain) in the uploaded file body targeting this endpoint.
  • Detect command injection in bbmdUpdate.php: monitor POST requests to /bbmdUpdate.php where hexMask or NAThexMask parameters contain shell metacharacters (e.g., semicolons, hash/comment characters, or OS commands like sleep).
  • Detect stored XSS in licenseServerUpdate.php: monitor POST requests to /licenseServerUpdate.php containing script injection payloads such as confirm(document.domain).
  • Monitor for multipart form-data uploads with Content-Type text/lic to ABB Aspect endpoints, which is the delivery mechanism for the licenseUpload.php stored XSS payload.
  • The exploit uses a specific WebKit multipart boundary; monitor for the boundary string '----WebKitFormBoundarymcNoKljWbBWAldlr' in POST bodies to licenseUpload.php as a PoC indicator.
  • ·The IP address 192.168.73.31 used in the PoC exploit code is a local lab/test IP and is NOT a malicious infrastructure indicator; do not use it as a network-level IOC.
  • ·The PHPSESSID cookie value 'xxx' in the PoC is a placeholder; real exploitation will use a valid authenticated session token. Detection should focus on the endpoint and payload, not the session value.
  • ·All three affected endpoints (licenseUpload.php, licenseServerUpdate.php, bbmdUpdate.php) require an authenticated session, meaning exploitation presupposes valid credentials or session hijacking.
