An information exposure vulnerability in the Palo Alto Networks GlobalProtect app on macOS enables a local user to learn the configured passcodes for disabling, disconnecting, or uninstalling the GlobalProtect app. After the passcode is known, the user can perform these actions even if the GlobalProtect app configuration would not normally permit them to do so.
Multiple improper certificate validation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enables an attacker to intercept encrypted communications and potentially compromise the endpoint. This can enable a local non-administrative operating system user or an attacker on the same subnet to redirect traffic to an unauthorized server and facilitate the installation of malicious software.
The GlobalProtect app on Linux, Windows, iOS and GlobalProtect UWP app are not affected.
A buffer overflow vulnerability exists in the Palo Alto Networks GlobalProtect™ app that enables a man in the middle attacker to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges. This vulnerability is triggered during the processing of requests and responses exchanged between Portal and Gateway.
The GlobalProtect app on iOS is not affected.
Multiple local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect™ app allow a local user to escalate their privileges to NT AUTHORITY\SYSTEM on Windows and root on macOS and Linux. This enables a non-administrative user to execute arbitrary commands with administrative privileges.
The GlobalProtect app on iOS, Android, Chrome OS and GlobalProtect UWP app are not affected.
DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.
