An unauthenticated remote attacker can get read access to files in the "/tmp" directory due to missing authentication.

The devices contain two hard coded user accounts with hardcoded passwords that allow an unauthenticated remote attacker for full control of the affected devices.

An unauthenticated remote attacker can execute OS commands via UDP on the device due to missing authentication.

An unauthenticated local attacker can decrypt the devices config file and therefore compromise the device due to a weak implementation of the encryption used.

An unauthenticated remote attacker can perform a brute-force attack on the credentials of the remote service portal with a high chance of success, resulting in connection lost.

An unauthenticated local attacker can gain admin privileges by deploying a config file due to improper input validation.

In Red Lion Europe mbCONNECT24 and mymbCONNECT24 and Helmholz myREX24 and myREX24.virtual up to and including 2.14.2 an improperly implemented access validation allows an authenticated, low privileged attacker to gain read access to limited, non-critical device information in his account he should not have access to.

Exposure of Sensitive Information to an unauthorized actor vulnerability in MB Connect Lines mbCONNECT24, mymbCONNECT24 and Helmholz' myREX24 and myREX24.virtual in versions <=2.13.3 allow an authorized remote attacker with low privileges to view a limited amount of another accounts contact information.

An Authorization Bypass vulnerability was found in MB Connect Lines mbCONNECT24, mymbCONNECT24 and Helmholz' myREX24 and myREX24.virtual version <= 2.13.3. An authenticated remote user with low privileges can change the password of any user in the same account. This allows to take over the admin user and therefore fully compromise the account.

A remote, unauthenticated attacker can enumerate valid users by sending specific requests to the webservice of MB connect line mymbCONNECT24, mbCONNECT24 and Helmholz myREX24 and myREX24.virtual in all versions through v2.11.2.
