Description
A denial of service vulnerability in Palo Alto Networks PAN-OS software enables an authenticated user with a read-only administrator role to 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.
