## Overview

An OS Command Injection vulnerability in TP-Link Archer BE230 v1.2(vpn modules) and BE3600 v1 allows adjacent 

authenticated 

attacker 

execute arbitrary code. Successful exploitation could allow an attacker to gain full administrative control of the device, resulting in severe compromise of configuration integrity, network security, and service availability.

This CVE covers one of multiple distinct OS command injection issues identified across separate code paths. Although similar in nature, each instance is tracked under a unique CVE ID.

This issue affects Archer BE230 v1.2 < 1.2.4 Build 20251218 rel.70420.

## Affected

- `archer_be230_firmware < 1.2.4`

## Remediation

Upgrade past the affected range:

- `archer_be230_firmware 1.2.4`
