Summary
Palo Alto Networks PAN-OS contains an authentication bypass vulnerability in its management web interface. This vulnerability allows an unauthenticated attacker with network access to the management web interface to bypass the authentication normally required and invoke certain PHP scripts.
Description
An authentication bypass in the Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to bypass the authentication otherwise required by the PAN-OS management web interface and invoke certain PHP scripts. While invoking these PHP scripts does not enable remote code execution, it can negatively impact integrity and confidentiality of PAN-OS. You can greatly reduce the risk of this issue by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practices deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .
