Описание
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.
Меры по смягчению последствий
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.
