Palo Alto GlobalProtect App 6.0.x < 6.0.15 / 6.2.x < 6.2.8-h13 / 6.3.x < 6.3.3-h14 Multiple Vulnerabilities (Global Un-Protect)

high Nessus Plugin ID 342126

Synopsis

A VPN client installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Palo Alto GlobalProtect App installed on the remote Windows host is 6.0.x prior to 6.0.15, 6.2.x prior to 6.2.8-h13, or 6.3.x prior to 6.3.3-h14. It is, therefore, affected by multiple vulnerabilities collectively known as Global Un-Protect:

 - Local privilege escalation vulnerabilities enable a local user to escalate their privileges to NT AUTHORITY\SYSTEM. (CVE-2026-0299)

 - A buffer overflow vulnerability enables a man-in-the-middle (MitM) attacker or a rogue gateway to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges. (CVE-2026-0297)

 - An improper input validation vulnerability in the Windows Pre-Logon Access Provider (PLAP) component enables a man-in-the-middle (MitM) attacker to execute arbitrary code with SYSTEM privileges. (CVE-2026-0298)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Palo Alto GlobalProtect App version 6.0.15, 6.2.8-h13, 6.3.3-h14 or later.
