CVE-2020-2041: Palo Alto Networks PAN-OS

High severity, CVSS 7.5. EPSS: 2.1% chance of exploitation in the next 30 days.

An insecure configuration of the appweb daemon of Palo Alto Networks PAN-OS 8.1 allows a remote unauthenticated user to send a specifically crafted request to the device that causes the appweb service to crash. Repeated attempts to send this request result in denial of service to all PAN-OS services by restarting the device and putting it into maintenance mode. This issue impacts all versions of PAN-OS 8.0, and PAN-OS 8.1 versions earlier than 8.1.16.

Affected products

• Palo Alto Networks PAN-OS: from 8.0.0, up to and including 8.0.20; from 8.1.0, before 8.1.16 (fixed in 8.1.16)
