CVE-2025-4057 is a vulnerability identified in Red Hat's AMQ Broker 7.13.0.OPR.1.GA, which is based on ActiveMQ Artemis. The core issue is that the password generated by the activemq-artemis-operator does not regenerate between separated Custom Resource (CR) dependencies. This means that when multiple CR dependencies are deployed or updated, the operator reuses the same password instead of generating a new, unique one. This behavior results in weak credential reuse across deployments, increasing the risk of credential compromise. The vulnerability has a CVSS 3.1 base score of 5.5 (medium severity), with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). The flaw primarily threatens confidentiality because an attacker with limited local privileges could potentially access sensitive information by exploiting the reused weak credentials. No known exploits are currently reported in the wild, and no official patches have been released at the time of disclosure. The vulnerability is particularly relevant in environments where multiple CR dependencies are deployed without manual password rotation or additional security controls. Since AMQ Broker is widely used in enterprise messaging systems, this vulnerability could expose sensitive messaging data if exploited.

For European organizations, the impact of CVE-2025-4057 centers on the potential unauthorized disclosure of sensitive messaging data due to reused weak credentials in AMQ Broker deployments. Organizations relying on ActiveMQ Artemis for critical messaging infrastructure could face confidentiality breaches if attackers gain local access or limited privileges on systems running the vulnerable operator. This could lead to exposure of internal communications, business data, or credentials that facilitate further lateral movement within networks. While the vulnerability does not directly affect data integrity or service availability, the confidentiality compromise could have regulatory implications under GDPR, especially if personal or sensitive data is transmitted via the messaging system. The medium severity rating suggests that while exploitation is feasible, it requires some level of local access, limiting remote exploitation risks. However, in complex cloud-native or containerized environments where operators manage multiple CR dependencies, the risk of credential reuse could be amplified. European organizations with mature security operations and credential management practices may mitigate the impact, but those with less stringent controls could be more vulnerable.

To mitigate CVE-2025-4057, European organizations should implement the following specific measures: 1) Manually rotate passwords generated by the activemq-artemis-operator between deployments or updates of CR dependencies to avoid credential reuse. 2) Restrict access to the activemq-artemis-operator and the underlying systems to trusted administrators only, minimizing the risk of local privilege exploitation. 3) Monitor and audit operator activity and credential usage to detect anomalous access patterns or reuse of credentials. 4) Employ network segmentation and least privilege principles to limit the scope of any potential compromise stemming from reused credentials. 5) Stay informed on Red Hat advisories and apply patches or updates promptly once available. 6) Consider integrating secrets management solutions that enforce unique, ephemeral credentials for each deployment or CR dependency. 7) Conduct regular security assessments and penetration tests focusing on operator-managed components to identify and remediate weaknesses. These targeted actions go beyond generic advice by focusing on the specific credential reuse mechanism and operational practices around the activemq-artemis-operator.
