The version of Palo Alto Networks PAN-OS running on the remote host is 7.1.x prior to 7.1.26 or 8.0.x prior to 8.1.13 or 8.1.x prior to 8.1.13 or 9.0.x prior to 9.0.6 or 9.1.x prior to 9.1.1. It is, therefore, affected by a vulnerability.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- An improper authorization vulnerability in PAN-OS that
mistakenly uses the permissions of local linux users
instead of the intended SAML permissions of the account
when the username is shared for the purposes of SSO
authentication. This can result in authentication bypass
and unintended resource access for the user. This issue
affects: PAN-OS 7.1 versions earlier than 7.1.26; PAN-OS
8.0 versions earlier than 8.0.21; PAN-OS 8.1 versions
earlier than 8.1.13; PAN-OS 9.0 versions earlier than
9.0.6; PAN-OS 9.1 versions earlier than 9.1.1.
