Vulnerability:
There is a vulnerability affecting the latest version (v2.1.103.0) of the
Cisco Trust Agent software for MacOS X that can allow an individual with
physical access to an endpoint to bypass authentication and gain
administrative access to the local machine.
Description:
When Cisco Secure Access Control Server is configured to display a message
to the end user following a posture check, the Cisco Trust Agent installed
on a MacOS X machine may display the message over the top of the login
screen when the client is powered up or rebooted. When the message is
displayed, a user can access System Preferences through the Apple Menu as
the root user and make changes to user accounts, including changing
existing passwords.
A malicious user with this access can change an administrator account
password without knowledge of the existing password and then proceed to
login using that account.
