Palo Alto Networks GlobalProtect vulnerabilities

A race condition in the Palo Alto Networks GlobalProtect client on macOS allows a locally authenticated low-privileged attacker to escalate privileges to root. The GlobalProtect app on Linux, Windows, iOS, Android, and Chrome OS is not affected.

An information exposure vulnerability in the Palo Alto Networks GlobalProtect app on macOS allows a local user to learn the configured passcodes for disabling, disconnecting, or uninstalling the app. After obtaining the passcode, the user can perform these actions even if the configuration would not normally permit it.

Multiple local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect app allow a local user to escalate privileges to NT AUTHORITY\SYSTEM on Windows and root on macOS and Linux.

A buffer overflow vulnerability in the Palo Alto Networks GlobalProtect app allows a man-in-the-middle attacker to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges. The vulnerability is triggered during the processing of requests and responses exchanged between Portal and Gateway.

Multiple improper certificate validation vulnerabilities in the Palo Alto Networks GlobalProtect app allow an attacker to intercept encrypted communications and potentially compromise the endpoint. A local non-administrative OS user or an attacker on the same subnet can redirect traffic to an unauthorized server and facilitate malicious software installation. The GlobalProtect app on Linux, Windows, iOS, and GlobalProtect UWP are not affected.
