Executive Summary

Apache TomEE running on JDK 21 or later fails to enforce EJB method authorization checks. This means attackers can call restricted EJB methods without proper permissions.

Detection Guidance

Detecting this vulnerability requires checking the Apache TomEE version and JDK version in use. Compare your installed TomEE version against 10.3.0 or 11.0.0-M2. Verify if JDK 21 or later is running. Commands: java -version for JDK check and grep for TomEE version in logs or startup scripts.

Impact Analysis

An attacker could exploit this to bypass security controls and access sensitive EJB methods, potentially leading to unauthorized data access or system manipulation.

Compliance Impact

This vulnerability could violate compliance requirements that mandate strict access controls, such as GDPR's data protection principles or HIPAA's security rules.

Mitigation Strategies

Upgrade Apache TomEE to version 10.3.0 or 11.0.0-M2 immediately. If upgrading is not possible, downgrade to a JDK version before 21 to prevent the authorization bypass. Ensure all EJB method access controls are reviewed post-upgrade.
