CVE-2024-0012

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.

What to do

• Recommended mitigation—The vast majority of firewalls already follow Palo Alto Networks and industry best practices. However, if you haven’t already, we strongly recommend that you secure access to your management interface according to our best practice deployment guidelines. Specifically, you should restrict access to the management interface to only trusted internal IP addresses to prevent external access from the internet. Additionally, if you have a Threat Prevention subscription, you can block these attacks using Threat IDs 95746, 95747, 95752, 95753, 95759, and 95763 (available in Applications and Threats content version 8915-9075 and later). For these Threat IDs to protect against attacks for this vulnerability, * Ensure that all the listed Threat IDs are set to block mode, * Route incoming traffic for the MGT port through a DP port https://docs.paloaltonetworks.com/best-practices/10-1/administrative-access-best-practices/administrative-access-best-practices/deploy-administrative-access-best-practices#id59206398-3dab-4b2f-9b4b-7ea500d036ba , e.g., enabling management profile on a DP interface for management access, * Replace the Certificate for Inbound Traffic Management https://docs.paloaltonetworks.com/best-practices/10-1/administrative-access-best-practices/administrative-access-best-practices/deploy-administrative-access-best-practices#id112f7714-8995-4496-bbf9-781e63dec71c , * Decrypt inbound traffic to the management interface so the firewall can inspect it htCNA workaround statement
• Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Additionally, management interface for affected devices should not be exposed to untrusted networks, including the internet.CISA KEV required action
