Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker to gain full control over the management features of OpenMQ by logging in as an administrator using the default username and password, which are often left unchanged. The attacker only needs access to the service port, making it easy for them to exploit this weakness if the default credentials are not updated.

Technical Description

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