Namely, the attacker must already have the ability to influence backend responses—such as injecting malicious headers like Content-Type or Content-Encoding—which typically implies a compromised or poorly controlled upstream service. In properly configured systems, frontend servers like Apache sanitize or strictly validate backend output, limiting exposure.

This can be done by commenting out the `LoadModule xml2enc_module modules/mod_xml2enc.so` directive in the Apache HTTP Server configuration. A service restart is required for the change to take effect.\n\n```bash\n# Edit the Apache configuration file, e.g., /etc/httpd/conf.modules.d/00-base.conf\n# Comment out the line:\n# LoadModule xml2enc_module modules/mod_xml2enc.so\n\n# Reload the httpd service\nsudo systemctl reload httpd\n```\n\n*Note: Disabling `mod_xml2enc` will cause any configurations relying heavily on `mod_proxy_html` or raw HTML/XML encoding conversions to function incorrectly or fail. Red Hat strongly recommends upgrading to a patched version of `httpd` as soon as it becomes available for your specific RHEL channel.*", "product_ids" : [
