AI-suggested
Users should upgrade affected Apache TomEE installations to version 10.3.0 or 11.0.0-M2, which contain fixes for this vulnerability. No other mitigations or temporary workarounds are indicated. The vendor advisory confirms these versions as fixed releases.
Description
Apache TomEE versions prior to 10.3.0 and 11.0.0-M2 contain a vulnerability where internal system EJBs used for remote deployment and configuration do not enforce administrative role checks when running with the default profile. This allows a remote unauthenticated attacker who can access the remote EJB endpoint to deploy arbitrary applications and execute code. Only installations with enabled system applications and remote EJB endpoints are affected. Upgrading to versions 10.3.0 or 11.0.0-M2 resolves the issue.
