Overview

AI description

Automated description summarized from trusted sources.

CVE-2024-0012 is an authentication bypass vulnerability found in the Palo Alto Networks PAN-OS software. This flaw allows an unauthenticated attacker with network access to the management web interface to gain administrator privileges. This access enables the attacker to perform administrative actions, manipulate the device's configuration, or potentially exploit other vulnerabilities that require authentication, such as CVE-2024-9474. The vulnerability affects PAN-OS versions 10.2, 11.0, 11.1, and 11.2 running on PA-Series, VM-Series, CN-Series firewalls, and Panorama (both virtual and M-Series appliances). Cloud NGFW and Prisma Access are not affected. The vulnerability exists within the management interface application, which uses PHP. A specific HTTP request with a Palo Alto Networks-related authentication header set to "off" can bypass the typical authentication process. This manipulated request is sent to the Nginx reverse proxy server, which forwards it without processing, granting the attacker unauthorized access.

Description: An authentication bypass in Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to gain PAN-OS administrator privileges to perform administrative actions, tamper with the configuration, or exploit other authenticated privilege escalation vulnerabilities like CVE-2024-9474 https://security.paloaltonetworks.com/CVE-2024-9474 . The risk of this issue is greatly reduced if you secure access to the management web interface by restricting access to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 . This issue is applicable only to PAN-OS 10.2, PAN-OS 11.0, PAN-OS 11.1, and PAN-OS 11.2 software. Cloud NGFW and Prisma Access are not impacted by this vulnerability.

Insights

Analysis from the Intruder Security Team

Published Nov 19, 2024

The vulnerabilities CVE-2024-0012 and CVE-2024-9474 can be combined to allow for an unauthenticated attacker to gain command line access to the vulnerable device. Compromising a vulnerable device would allow an attacker to gain access to internal networks as these devices are designed to sit on the edge of networks.

The vulnerability is due to a misconfigured Nginx instance and a command injection vulnerability, both of which are exploitable in the devices default state. Watchtowr have released a technical blog post detailing the vulnerability and its exploitation.

Palo Alto have released patches and hotfixes for the PAN-OS vulnerabilities, details are available here and here.
