Cisco Secure ACS 3.x Password??

Overview:

Cisco Secure ACS is a central administration platform for
Cisco network devices. It controls authentication and
authorization for enrolled devices. Administrative
passwords for locally-defined users are stored in such a
way they can be obtained from the Windows registry. If
remote registry access is enabled, this can be done over
the network.

Details:

Cisco Secure ACS 3.x for Windows stores passwords for
administrative users in the registry. The passwords are
encrypted using the Crypto API Microsoft Base Cryptographic
Provider v1.0. Along with the passwords, ACS also stores
the key used to encrypt the information. This information
can easily be obtained locally by a Windows administrator,
and if remote registry access is enabled, it can be
obtained over the network. With this, the clear-text
passwords can be recovered by decrypting the information
in the registry with the supplied key. Access to these
passwords provides access to all Cisco devices controlled
by the ACS server.
