## Overview

Jooan JA-A12 IP cameras with firmware 009_20171107 and 05.02.31.105 contain a remote code execution vulnerability that allows unauthenticated attackers to run root commands via hard-coded credentials. Attackers send singleCMD=SetDiagMode to /goform/SingleHandlebyCommand with an attacker-chosen authserverip and authcode, making the jooandiag daemon execute their commands through /bin/sh, giving full device control.

## Affected

- `JA-A12 009_20171107`
