A vulnerability was found in mod_proxy_cluster. The issue is that the <Directory> directive should be replaced by the <Location> directive as the former does not restrict IP/host access as `Require ip IP_ADDRESS` would suggest. This means that anyone with access to the host might send MCMP requests that may result in adding/removing/updating nodes for the balancing. However, this host should not be accessible to the public network as it does not serve the general traffic.

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2025:9997 advisory.

    The mod_proxy_cluster module is a plugin for the Apache HTTP Server that provides load-balancer     functionality.

    Security Fix(es):

    * mod_proxy_cluster: mod_proxy_cluster unauthorized MCMP requests (CVE-2024-10306)
