Description
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.
