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.

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.

A privilege escalation vulnerability in the Palo Alto Networks GlobalProtect app on Windows allows a locally authenticated non-administrative Windows user to escalate their privileges to NT AUTHORITY/SYSTEM through the use of the repair functionality offered by the .msi file used to install GlobalProtect.

A privilege escalation (PE) vulnerability in the Palo Alto Networks GlobalProtect app on Windows devices enables a local user to execute programs with elevated privileges.

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.

A local privilege escalation (PE) vulnerability in the Palo Alto Networks GlobalProtect app on Windows enables a local user to execute programs with elevated privileges.

A local file deletion vulnerability in the Palo Alto Networks GlobalProtect app on Windows devices enables a user to delete system files from the endpoint with elevated privileges through a race condition.

A stack-based 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 issue impacts: GlobalProtect app 5.1 versions earlier than GlobalProtect app 5.1.9 on Windows; GlobalProtect app 5.2 versions earlier than GlobalProtect app 5.2.8 on Windows; GlobalProtect app 5.2 versions earlier than GlobalProtect app 5.2.8 on the Universal Windows Platform; GlobalProtect app 5.3 versions earlier than GlobalProtect app 5.3.1 on Linux.

When the pre-logon feature is enabled, a missing certification validation in Palo Alto Networks GlobalProtect app can disclose the pre-logon authentication cookie to a man-in-the-middle attacker on the same local area network segment with the ability to manipulate ARP or to conduct ARP spoofing attacks. This allows the attacker to access the GlobalProtect Server as allowed by configured Security rules for the 'pre-login' user. This access may be limited compared to the network access of regular users. This issue affects: GlobalProtect app 5.0 versions earlier than GlobalProtect app 5.0.10 when the prelogon feature is enabled; GlobalProtect app 5.1 versions earlier than GlobalProtect app 5.1.4 when the prelogon feature is enabled.

A race condition vulnerability Palo Alto Networks GlobalProtect app on Windows allows a local limited Windows user to execute programs with SYSTEM privileges. This issue can be exploited only while performing a GlobalProtect app upgrade. This issue affects: GlobalProtect app 5.0 versions earlier than GlobalProtect app 5.0.10 on Windows; GlobalProtect app 5.1 versions earlier than GlobalProtect app 5.1.4 on Windows.

An unquoted search path vulnerability in the Windows release of Global Protect Agent allows an authenticated local user with file creation privileges on the root of the OS disk (C:\) or to Program Files directory to gain system privileges. This issue affects Palo Alto Networks GlobalProtect Agent 5.0 versions before 5.0.5; 4.1 versions before 4.1.13 on Windows;

A Local Privilege Escalation vulnerability exists in the GlobalProtect Agent for Windows 5.0.3 and earlier, and GlobalProtect Agent for Windows 4.1.12 and earlier, in which the auto-update feature can allow for modification of a GlobalProtect Agent MSI installer package on disk before installation.

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.
