Description

OpenMQ exposes a TCP-based management service (imqbrokerd) that by default requires<br /> authentication. However, the product ships with a default administrative account (admin/<br /> admin) and does not enforce a mandatory password change on first use. After the first<br /> successful login, the server continues to accept the default password indefinitely without<br /> warning or enforcement.<br /> <br /> <br /> In real-world deployments, this service is often left enabled without changing the default<br /> credentials. As a result, a remote attacker with access to the service port could authenticate<br /> as an administrator and gain full control of the protocol’s administrative features.
