  • →Exploit targets HTTP POST requests to the exact URI /goform/openNetworkGateway (URI length is exactly 26 bytes); match on this path to scope detection.
  • →The vulnerable parameter is wpapsk_crypto2_4g (URL-encoded as wpapsk_crypto2_4g=); look for this parameter name in the POST body.
  • →Buffer overflow is triggered by supplying 100 or more consecutive non-ampersand characters as the value of wpapsk_crypto2_4g; use the PCRE /^[^&]{100,}(?:&|$)/R anchored to the parameter value.
  • →Attack is plaintext only (tls_state plaintext); detection should be applied at the perimeter and internally on unencrypted HTTP traffic.
  • →The exploit is publicly available and maps to MITRE ATT&CK T1190 (Exploit Public-Facing Application) under tactic TA0001 (Initial Access).
  • ·Affected firmware version is Tenda A15 15.13.07.13; ensure detection is scoped to this device/version to reduce false positives.
  • ·The vulnerable function is fromSetWirelessRepeat inside /goform/openNetworkGateway; the overflow occurs specifically in the wpapsk_crypto2_4g argument, not other parameters on the same endpoint.
