A buffer overflow vulnerability in the XML processing functionality of Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to the management web or dataplane interface to cause a denial of service (DoS) condition on VM-Series firewalls or execute arbitrary code with root privileges on the PA-Series firewalls. The security risk posed by this issue is minimized when the management interface is restricted 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 . Panorama is impacted by this vulnerability.
