# mbCONNECT24 / myREX24V2: OS command injection in backend backup restore (fixed in 2.21.0)

Link for people: https://infrastack.ai/live/CVE-2026-60039 (this .md is for agents)

A high-privileged remote user of the mbCONNECT24/mymbCONNECT24 (MB connect line) or myREX24V2/myREX24V2.virtual (Helmholz) backend can inject OS commands through the backup restore function, leading to code execution (CWE-78). Vendor CVSS 3.1 is 7.2; fixed in 2.21.0.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:mbCONNECT24 affected < 2.21.0 fixed 2.21.0
- vendor:mymbCONNECT24 affected < 2.21.0 fixed 2.21.0
- vendor:myREX24V2 affected < 2.21.0 fixed 2.21.0
- vendor:myREX24V2.virtual affected < 2.21.0 fixed 2.21.0

## How to check

Check the firmware/software version of your mbCONNECT24, mymbCONNECT24, myREX24V2 or myREX24V2.virtual instance (admin backend). Anything below 2.21.0 is affected per the vendor advisories.

## Fix

Update the instance to version 2.21.0 (per VDE-2026-079 and VDE-2026-141).

## From the sources

A high privileged remote attacker can perform a code injection in the backends backup restore function leading to code execution. This can result in a total loss of confidentiality, integrity and availability.
