CVE-2022-47124Network attack vector

Unauthenticated memory corruption via oversized WEP key

Published Dec 30, 2022 · Updated Apr 11, 2025

Out-of-bounds write in Tenda A15 15.13.07.13 allows remote attackers to corrupt memory through a crafted wepkey4 value. The /goform/WifiBasicSet handler accepts an overlong wepkey4 parameter and writes beyond a stack buffer. No authentication or user interaction is required to submit the request, while the public record does not state whether exploitation yields a crash or code execution.
