Affected scope and exposure questions

The current feed maps Apache Software Foundation/org.apache.openejb:openejb-core (generic), Apache Software Foundation/org.apache.tomee:openejb-core (generic). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
PackageAffected rangeFixed version
Apache Software Foundation/org.apache.openejb:openejb-coregeneric>=4.5.1 <=4.7.5Not reported
Apache Software Foundation/org.apache.tomee:openejb-coregeneric>=7.0.0-M1 <10.0.0-M1 || >=10.0.0-M1 <10.3.0 || >=11.0.0-M1 <11.0.0-M210.3.0, 11.0.0-M2

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Apache Software Foundation/org.apache.openejb:openejb-core, Apache Software Foundation/org.apache.tomee:openejb-core.
  2. 2Review the reported fix. Update Apache Software Foundation/org.apache.tomee:openejb-core to 10.3.0 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

  • Source referencelists.apache.org
Upstream source description

The internal system EJBs used for remote deployment and configuration did not enforce their administrative role check when the server ran with the default profile. A remote unauthenticated attacker able to reach the remote EJB endpoint could deploy arbitrary applications and execute code. Only installations that enabled the system applications and a remote EJB endpoint are exposed. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
