CVE-2022-36569Network attack vector

Authenticated memory corruption via oversized deviceList input

Published Aug 31, 2022 · Updated Aug 3, 2024

Stack-based buffer overflow in Tenda AC9 firmware 15.03.05.19 allows remote authenticated users to corrupt memory through deviceList. The /goform/setMacFilterCfg handler accepts an oversized deviceList value and writes beyond a stack buffer's bounds. Low-privileged management access and network reachability are required; the public record does not establish whether exploitation ends in a crash or controlled code execution.
