Platform-mbean RBAC Bypass in JBoss EAP

Executive Summary

This vulnerability is in the platform-mbean component of JBoss EAP, which manages JVM metrics and configurations. It occurs because the handler for the read-resource operation fails to perform required Role-Based Access Control checks. This allows low-privileged authenticated users, like those with the Monitor role, to view sensitive system properties and JVM configurations that should be restricted.

Detection Guidance

To detect this vulnerability, check JBoss EAP logs for unauthorized read-resource operations on the platform-mbean component. Monitor for access attempts by low-privileged users like the Monitor role viewing sensitive JVM configurations. Use commands like grep to search logs for 'read-resource' operations targeting platform-mbean paths.

Mitigation Strategies

Apply the latest JBoss EAP patches if available. Restrict access to management interfaces by ensuring only authorized roles can perform read-resource operations. Review and update RBAC policies to enforce strict access controls on platform-mbean resources.
