Complex products such as PAN firewalls include protections that make this process difficult regardless of the vulnerability. 'As is the case with many closed-source products, simply setting up an environment in which to develop an exploit is challenging. This process allowed us to identify the components an attacker would have to exploit in order to compromise the device,' Portnoy explained.

We then devoted resources into assessing the attack surface of the firewall itself in a lab environment. Randori believes the best way to identify potential points of attack is to assess the attack surface. 'Once an attacker has control over the firewall, they will have visibility into the internal network and can proceed to move laterally. Palo Alto has released an update that patches CVE-2021-3064 after being notified about the issue in September.Īaron Portnoy, principal scientist at Randori, told ZDNet that the original catalyst for their research into Palo Alto Networks firewalls was identifying its presence on customer perimeters. It is used by a number of Fortune 500 companies and other global enterprises. The issue affects multiple versions of PAN-OS 8.1 prior to 8.1.17, and Randori said it found numerous vulnerable instances exposed on internet-facing assets, in excess of 70,000 assets.

The zero-day - which has a severity rating of 9.8 - allows for unauthenticated, remote code execution on vulnerable installations of the product.
