CVE-2025-4057 identifies a security weakness in the ActiveMQ Artemis component of Red Hat's AMQ Broker version 7.13.0.OPR.1.GA. The vulnerability stems from the activemq-artemis-operator's failure to regenerate passwords between separated Custom Resource (CR) dependencies, resulting in persistent reuse of the same credentials across different instances or components. This behavior weakens the security posture by increasing the risk that compromised credentials can be leveraged across multiple resources, thereby undermining confidentiality. The vulnerability requires local access with low privileges (AV:L/PR:L), does not require user interaction (UI:N), and affects confidentiality (C:H) but not integrity or availability. The CVSS 3.1 base score is 5.5, reflecting a medium severity level. No known public exploits exist yet, but the flaw could be exploited in environments where attackers have limited local access, potentially leading to unauthorized data disclosure. The issue is specific to AMQ Broker 7.13.0.OPR.1.GA and related ActiveMQ Artemis operator implementations that manage CR dependencies without proper password regeneration.

The primary impact of this vulnerability is the potential compromise of confidentiality due to weak credential reuse. Attackers with low-level local privileges could exploit the reused passwords to access multiple components or services managed by the activemq-artemis-operator, increasing the attack surface and risk of unauthorized data exposure. Although the vulnerability does not affect integrity or availability, the exposure of sensitive messaging data or credentials could have significant consequences for organizations relying on AMQ Broker for critical messaging infrastructure. This risk is heightened in multi-tenant or shared environments where CR dependencies are separated but share credentials. The lack of password regeneration undermines isolation between components, facilitating lateral movement and data leakage. Organizations worldwide using this specific AMQ Broker version could face targeted attacks, especially in environments where local access controls are weak or where attackers have already gained footholds.

To mitigate CVE-2025-4057, organizations should first apply any available patches or updates from Red Hat that address the password regeneration issue in the activemq-artemis-operator. If patches are not yet available, administrators should manually enforce password regeneration between CR dependencies by scripting or configuration management to ensure unique credentials per resource. Additionally, implement strict local access controls and monitoring to detect unauthorized access attempts. Employ network segmentation to limit lateral movement within messaging infrastructure. Regularly audit and rotate credentials used by ActiveMQ Artemis components. Consider deploying multi-factor authentication where possible and use secrets management tools to handle credentials securely. Finally, monitor logs for unusual authentication patterns that may indicate exploitation attempts.
