This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Windows host is potentially affected by a privilege
elevation vulnerability.

Description :

The remote Windows host is potentially affected by a vulnerability in
the way that Active Directory distributes passwords that are
configured using Group Policy preferences. This could allow a remote
attacker to retrieve and decrypt passwords stored with Group Policy
preferences.

The following group policy preferences extensions are affected :

- Local user and group
- Mapped drives
- Services
- Scheduled tasks (Uplevel)
- Scheduled tasks (Downlevel)
- Immediate tasks (Uplevel)
- Immediate tasks (Downlevel)
- Data sources

Note that this update does not remove any existing Group Policy
Objects (GPOs). GPOs using the mentioned group policy preferences will
need to be updated to not distribute passwords.
