Palo Alto Networks PAN-OS 8.1.x < 8.1.21 / 9.0.x < 9.1.11 / 9.1.x < 9.1.11 / 10.0.x < 10.0.7 Vulnerability

medium Nessus Plugin ID 158760


The remote PAN-OS host is affected by a vulnerability


The version of Palo Alto Networks PAN-OS running on the remote host is 8.1.x prior to 8.1.21 or 9.0.x prior to 9.1.11 or 9.1.x prior to 9.1.11 or 10.0.x prior to 10.0.7. It is, therefore, affected by a vulnerability.

- 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to PAN-OS 8.1.21 / 9.1.11 / 9.1.11 / 10.0.7 or later
