url/goform/P2pListFilter↗

→Detect unauthenticated POST requests to /goform/fromP2pListFilter (or /goform/P2pListFilter) on Tenda FH451 routers with an oversized 'list' parameter (>3500 bytes) in the POST body, indicative of stack-based buffer overflow exploitation. ↗
→The exploit targets the 'page' argument (also observed as 'list' in the PoC POST body) of the fromP2pListFilter function. Monitor for abnormally large values in POST parameters to this endpoint. ↗
→After sending overflow payloads, the exploit confirms DoS by checking if the router stops responding to ICMP ping. Correlate router unresponsiveness with prior POST requests to /goform/fromP2pListFilter. ↗

·The vulnerability affects only Tenda FH451 firmware version 1.0.0.9. Detections should be scoped to this specific device/firmware version to reduce false positives. ↗
·The endpoint /goform/fromP2pListFilter is unprotected and requires no authentication, meaning exploit attempts will not be preceded by any login activity — authentication-based detection will not catch this attack. ↗
