Title
Firewalld: firewalld: local unprivileged user can modify firewall state due to d-bus setter mis-authorization
Summary
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.
