Description

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.

 - 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.
