  • →Attack uses HTTP POST method targeting the URI /goform/WifiWpsStart with a URI size of exactly 20 bytes.
  • →The overflow is triggered via the 'index' parameter in the POST body; look for 'index=' (encoded as 'index|3d|') followed by 100 or more non-ampersand characters.
  • →Traffic is expected in plaintext (not TLS); deploy detection at perimeter and internal network boundaries.
  • →The vulnerability is a stack-based buffer overflow triggered remotely by manipulating the 'index' argument of formWifiWpsStart. ↗
  • ·The Snort/Suricata rule (sid:2064111) covers multiple CVEs simultaneously (CVE-2025-45429, CVE-2024-2896, CVE-2024-2811, CVE-2024-2706); tune or split as needed to isolate CVE-2024-2706 detections.
