GlobalProtect-openconnect versions prior to 2.0.0 (exclusive) are affected by incorrect access control in GPService through DBUS, GUI. The way GlobalProtect-Openconnect is set up enables arbitrary users to start a VPN connection to arbitrary servers. By hosting an openconnect compatible server, the attack can redirect the entire host’s traffic via their own server.
