1) Insufficient Control of Network Message Volume (CVE-ID: CVE-2022-0028)

CWE-ID: CWE-406 - Insufficient Control of Network Message Volume (Network Amplification)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:A/U:Green


The vulnerability allows a remote attacker to perform DoS attack.

The vulnerability exists due to a misconfiguration of the PAN-OS URL filtering policy. A remote attacker can conduct reflected and amplified TCP denial-of-service (RDoS) attacks against other other system using the affected device as the source of the attack.

Successful exploitation of the vulnerability requires that the firewall configuration has a URL filtering profile with one or more blocked categories assigned to a security rule with a source zone that has an external facing network interface.
