CVE-2022-25554Public exploitNetwork attack vector

Service interruption via unchecked deviceId copy

Published Mar 9, 2022 · Updated Aug 3, 2024

Buffer overflow in Tenda AX1806 1.0.0.1 allows remote attackers to interrupt router service via a crafted deviceId parameter. The saveParentControlInfo handler copies the HTTP deviceId value with strcpy into a heap-backed destination without enforcing its size. An unauthenticated POST can trigger memory corruption; published reports do not distinguish a crash from a reboot and document no data impact.
