high Nessus Plugin ID 370478

Synopsis

A VPN client installed on the remote macOS host is affected by a local privilege escalation vulnerability.

Description

The version of Palo Alto GlobalProtect App installed on the remote macOS host is 6.2.x prior to 6.2.8-h15, or 6.3.x prior to 6.3.3-h16. It is, therefore, affected by a local privilege escalation vulnerability:

 - A local privilege escalation vulnerability in the Palo Alto Networks GlobalProtect app enables a local user to escalate their privileges to root on macOS. This enables a non-administrative user to execute arbitrary commands with administrative privileges. (CVE-2026-0315)

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

Solution

Upgrade to Palo Alto GlobalProtect App version 6.2.8-h15, 6.3.3-h16 or later.
