✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Disabling mod_dav_lock and restarting httpd will mitigate this flaw. 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, ensure that Apache HTTP Server (httpd) is configured to proxy only to trusted backend services. Implement robust network segmentation and access controls to restrict unauthorized access to backend servers. If proxying to potentially untrusted backends is necessary, consider deploying a Web Application Firewall (WAF) or an additional content inspection layer to filter malicious response headers.
