Palo Alto GlobalProtect App Windows 6.x < 6.2.8-h3 / 6.3.x < 6.3.3-h2 Improper Certificate Validation (CVE-2025-2183)

high Nessus Plugin ID 252960

Synopsis

A VPN client installed on remote host is affected by an improper certificate validation vulnerability.

Description

The version of Palo Alto GlobalProtect App installed on the remote Windows host is 6.x prior to 6.2.8-h3 or 6.3.x prior to 6.3.3-h2. It is, therefore, affected by an improper certificate validation vulnerability:

 - An insufficient certificate validation issue in the Palo Alto Networks GlobalProtect app enables attackers to connect the GlobalProtect app to arbitrary servers. This can enable a local non-administrative operating system user or an attacker on the same subnet to install malicious root certificates on the endpoint and subsequently install malicious software signed by the malicious root certificates on that endpoint.

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-h3, or 6.3.3-h2 or later
