# mbCONNECT24, mymbCONNECT24 and myREX24V2 backups use a weak static password, letting an unauthenticated attacker read them

Link for people: https://infrastack.ai/live/CVE-2026-60044 (this .md is for agents)

Backups created by MB connect line mbCONNECT24/mymbCONNECT24 and Helmholz myREX24V2/myREX24V2.virtual use a weak static password. An unauthenticated remote attacker can access their content (CVSS 7.5, confidentiality only). Fixed in 2.21.0. Reported by SySS GmbH; CERT@VDE coordinated.

_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 installed firmware/software version of your mbCONNECT24, mymbCONNECT24, myREX24V2 or myREX24V2.virtual instance; anything below 2.21.0 is affected. Treat existing backup files as readable by anyone who obtains them.

## Fix

Update the instance to version 2.21.0 (vendor remediation in VDE-2026-079 and VDE-2026-141).

Advisory does not say how an attacker obtains the backup, nor how to read the version; no exploitation or PoC seen. how_to_check not marked verified.

## From the sources

The backups created by the application use a weak static password allowing an unauthenticated remote attacker to access their content. This can result in a total loss of confidentiality.
