✅ Remediation

Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. The References section of this erratum contains a download link (you must log in to download the update). Workaround: This flaw may be mitigated by temporarily disabling routes that allows arbitrary writes and executions (camel-exec and camel-file) Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: To mitigate this issue, restrict outbound network access for applications that utilize Apache Neethi's PolicyReference API, especially if they process untrusted input that could influence the URI used for fetching remote policies. Implement firewall rules or network policies to limit the protocols and IP addresses to which the application can connect. This may impact application functionality if legitimate remote policy fetching is required.
