Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/firewalld, Red Hat/openshift/ose-rhel-coreos-8.
  2. 2Review the reported fix. Source-reported workaround: To mitigate this issue, ensure that the firewalld desktop policy is not active on systems where local unprivileged user access is a concern. If firewalld is not required, it can be disabled. Disabling firewalld may impact network services that rely on it. To disable firewalld: sudo systemctl stop firewalld sudo systemctl disable firewalld A system restart or service reload may be required for changes to take full effect.

Upstream source description

A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.
