CVE-2012-5626Network attack vector

Unauthorized EJB actions via ignored RunAs roles

Published Jan 23, 2020 · Updated Aug 6, 2024

Authorization bypass in affected Red Hat JBoss middleware releases allows remote attackers to execute EJB methods with unintended roles. EJBJACCPolicyModuleDelegate.checkWithPolicy derives current roles from the caller principal even when a run-as principal exists, ignoring roles declared with @RunAs. Reachability requires deployed EJB code that uses @RunAs; successful calls are authorized with caller roles rather than the component's declared run-as identity.
