Description

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.
