Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
On an F5OS system, if the root user had previously configured the system to allow login via SSH key-based authentication, and then enabled Appliance Mode; access via SSH key-based authentication is still allowed. For an attacker to exploit this vulnerability they must obtain the root user's SSH private key.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
