CVE-2022-46434Network attack vector

Code execution via crafted firmware image

Published Dec 20, 2022 · Updated Apr 16, 2025

Code execution in TP-Link TL-WA7510N V1 firmware 3.12.6 and earlier allows remote attackers to run code via a crafted firmware image. The firmware update path accepts an attacker-crafted image, but the public record does not disclose which image-validation operation fails. Exploitation requires a user to upload the image; installation executes attacker-controlled code or interrupts service, and the record does not identify whether interruption means a crash, reboot, or other failure.
