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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
