Overview

CVE-2020-2033 is a medium-severity vulnerability. It was published on June 10, 2020 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
