DHCP can add routes to a client’s routing table via the classless static route option (121).

GlobalProtect Agent 4.1.0 for Windows and GlobalProtect Agent 4.1.10 and earlier for macOS may allow a local authenticated attacker who has compromised the end-user account and gained the ability to inspect memory, to access authentication and/or session tokens and replay them to spoof the VPN session and gain access as the user.
