Networkmanager-fortisslvpn: networkmanager-fortisslvpn: local privilege escalation to root via crlf injection in vpn profile credentials

Description

A flaw was found in NetworkManager-fortisslvpn, the FortiSSLVPN plugin for NetworkManager. The nm-fortisslvpn-service improperly handles carriage-return/line-feed (CR/LF) characters in VPN connection profile credentials. A local unprivileged user can exploit this by crafting a malicious VPN profile to inject additional configuration directives. This can lead to arbitrary code execution with root privileges when the crafted VPN connection is activated.
