## 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 Archer VX800v v1 due to insufficient input sanitization of the domain name parameter. An adjacent attacker who can access the relevant HTTP interface can modify the parameter to inject shell metacharacters, resulting in arbitrary code execution with root privileges. Successful exploitation may allow remote code execution and 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.
