Technical summary

The vulnerability exists in GlobalProtect™ when configured with SAML authentication. An attacker can fixate a session ID, then trick a legitimate user into authenticating through a malicious link. Once authenticated, the attacker possesses a valid session and can impersonate the user to perform unauthorized actions. The attack requires user interaction (clicking a malicious link) but needs no privileges and has low attack complexity. CVSS vector indicates network attack vector, scope change, high confidentiality impact, low integrity impact, and high availability impact.

Defensive priority

CRITICAL

Recommended defensive actions

  • Upgrade Palo Alto Networks Virtual NGFW to version 11.1.8 by contacting customer support for patch and update information
