"The version of Palo Alto Networks PAN-OS running on the remote host is 11.1.x prior to 11.1.16-h3, 11.2.x prior to
11.2.16, 12.1.x prior to 12.1.10-h2, or 12.2.x prior to 12.2.4. It is, therefore, affected by a vulnerability.

    A denial of service vulnerability in Palo Alto Networks PAN-OS software enables an authenticated user with
    a read-only administrator roleto cause a denial of service (DoS) condition by sending a specially crafted
    API request.

    The security risk posed by this issue is significantly minimized by restricting access to the management
    web interface 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).

    Cloud NGFW, Panorama, and Prisma Access are not affected by this vulnerability.
