  • →Exploit uses HTTP POST method targeting the /goform/P2pListFilter endpoint with a URI length of exactly 21 bytes. ↗
  • →The overflow is triggered via the 'page' parameter in the POST body, where the value (after '=') is 100 or more characters, optionally followed by '&' or end of body. ↗
  • →Attack is plaintext (non-TLS) and targets networking equipment at the perimeter or internally; monitor for large 'page' parameter values in POST requests to Tenda devices. ↗
  • →Public exploit code is available; reference the GitHub PoC repository for additional indicators. ↗
  • ·The Snort/Suricata rule (sid:2062169) targets only plaintext HTTP traffic; encrypted HTTPS traffic to the device will not be detected by this signature. ↗
  • ·The PCRE threshold of 100+ characters for the 'page' parameter value may need tuning to reduce false positives or catch shorter overflow payloads depending on the actual vulnerable buffer size. ↗
  • ·Affected version is specifically Tenda CH22 1.0.0.1; the rule metadata broadly tags 'Networking_Equipment' — scope detection to confirmed affected firmware versions to avoid alert fatigue. ↗
