## Affected

- TP-Link Systems Inc. Archer VX1800v v1: fixed in 0.16.0 2.0.0 v6092.0 Build 260521 RC.7927n

## Description

An OS command injection vulnerability exists in the TR-069 / CWMP management interface of Archer VX1800v v1 due to insufficient input validation and sanitization of parameters, allowing crafted input to be executed as system-level commands. Exploitation requires specific conditions such as TR-069 being enabled and ability to influence ACS-delivered commands, compromise or control an ACS server. Successful exploitation may allow arbitrary command execution with root privileges, resulting in complete compromise of the device.

## What to do

- Check your stack: if you ship or depend on TP-Link Systems Inc. Archer VX1800v v1, upgrade to a fixed version (0.16.0 2.0.0 v6092.0 Build 260521 RC.7927n) per the references below.
