CVE-2022-46914Network attack vector

Code execution via crafted firmware image upload

Published Dec 20, 2022 · Updated Apr 16, 2025

Improper firmware validation in TP-Link TL-WA801N and TL-WA801ND V1 3.12.16 and earlier allows attackers to execute arbitrary code. The update process accepts a crafted firmware image, but published sources do not identify the failed validation check or code locus. The published record requires user interaction but no prior privileges; successful exploitation can replace device code or interrupt service.
