CVE-2022-46912Network attack vector

Code execution via crafted firmware image upload

Published Dec 20, 2022 · Updated Apr 16, 2025

Firmware update flaw in TP-Link TL-WR841N and TL-WR841ND V7 3.13.9 and earlier allows attackers to execute code via a crafted image. The updater accepts an attacker-crafted firmware image, but the public disclosure does not identify the failed validation step or malformed field. Exploitation requires user interaction during the network upload; successful processing grants device-level code execution or interrupts service.
