CVE-2022-0022 PAN-OS: Use of a Weak Cryptographic Algorithm for Stored Password Hashes

Medium 4.1 Published 9 Mar 2022 Updated 16 Sep 2024

Weak password hashing in PAN-OS allows attackers with config access to crack admin and user passwords, leading to account takeover.

Exploited in the wild: Not known
Login needed: An administrator
Attackable: Local or same network only
Victim action needed: Not needed
Fix: None listed

What is CVE-2022-0022?

CVE-2022-0022 is a medium-severity vulnerability in Paloaltonetworks Pan-Os, published on 9 Mar 2022. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

Usage of a weak cryptographic algorithm in Palo Alto Networks PAN-OS software where the password hashes of administrator and local user accounts are not created with a sufficient level of computational effort, which allows for password cracking attacks on accounts in normal (non-FIPS-CC) operational mode. An attacker must have access to the account password hashes to take advantage of this weakness and can acquire those hashes if they are able to gain access to the PAN-OS software configuration. Fixed versions of PAN-OS software use a secure cryptographic algorithm for account password hashes. This issue does not impact Prisma Access firewalls. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.21; All versions of PAN-OS 9.0; PAN-OS 9.1 versions earlier than PAN-OS 9.1.11; PAN-OS 10.0 versions earlier than PAN-OS 10.0.7.

Weakness: CWE-916
