Maintain or revert caller propagation to the default 'none' setting in the IIOP subsystem configuration:\nRun the following management CLI command:\n`/subsystem=iiop-openjdk:write-attribute(name=caller-propagation,value=none)`\nEnsure that application deployment descriptors (such as jboss-ejb3.xml) do not explicitly override caller propagation to 'supported'.\n\n2. Restrict network reachability:\nBlock external access to the CORBA/IIOP port (default TCP port 3528) using firewall rules, or restrict access strictly to trusted application networks:\n`firewall-cmd --remove-port=3528/tcp --permanent && firewall-cmd --reload`\n\n3. Enforce transport-level security:\nIf caller propagation is required for your architecture, configure the IIOP subsystem to require SSL/TLS with client certificate authentication by setting `server-requires-ssl=\"true\"`, or enforce mandatory authentication via the `as-context` configuration.\n\nCaveats:\nDisabling caller propagation prevents client security identity forwarding across remote IIOP EJB calls, which may impact applications relying on distributed identity propagation. Restricting firewall access will prevent external clients outside authorized networks from connecting to IIOP services.\n\nWarning:\nApplying configuration changes via the JBoss management CLI requires reloading the runtime service (`:reload`), which will temporarily interrupt active client connections." } ], "timeline": [ { "lang": "en", "time": "2026-06-23T02:49:58.722Z", "value": "Reported to Red Hat." }, { "lang": "en", "time": "2026-10-27T00:00:00.000Z", "value": "Made public." } ], "providerMetadata": { "orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-10-29T06:07:33.732Z" }, "x_generator": { "engine": "cvelib 1.8.0" } } } }
