✅ Remediation

For on-premise installations, before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. It is recommended to halt the server by stopping the JBoss Application Server process before installing this update; after installing the update, restart the server by starting the JBoss Application Server process. The References section of this erratum contains a download link (you must log in to download the update). Workaround: The following conditions are needed for an exploit, we recommend avoiding all if possible: * Deserialization from sources you do not control * `enableDefaultTyping()` * `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS` Workaround: This vulnerability relies on jdom (org.jdom) or jdom2 (org.jdom2) being present in the application's ClassPath. Applications using jackson-databind that do not also use jdom or jdom2 are not impacted by this vulnerability. Workaround: The following conditions are needed for an exploit, we recommend avoiding all if possible * Deserialization from sources you do not control * `enableDefaultTyping()` * `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`
