Software Versions and Fixes
===========================
When considering software upgrades, also consult
http://www.cisco.com/go/psirt and any subsequent advisories to
determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance.
This vulnerability is fixed in software release 1.0.4.MR2, which will
be available on September 30th, 2011.
Cisco ISE release 1.0.4.MR2 will be made available in two formats:
* as an ISO image containing a complete installation image, which
can be used for a new install or for completely reimaging an
existing installation.
* as an application bundle that can be used to upgrade an existing
Cisco ISE release 1.0 (1.0.3.377) or Cisco ISE release 1.0MR
(1.0.4.558) installation to Cisco ISE release 1.0.4.MR2.
Those files can be downloaded from the Software Center on Cisco.com
by visiting http://www.cisco.com/cisco/software/navigator.html
The files will be accessible using the following path:
Products > Security > Identity Management > Cisco Identity Services
Engine > Cisco Identity Services Engine Software 1.0 > Identity
Services Engine System Software-1.0 MR
On installation, either as a clean install from the ISO image or
application bundle for upgrading an existing install, Cisco ISE
release 1.0.4.MR2 will:
* remove the existing database default credentials, and
* request the user to provide new database credentials
Workarounds
===========
There is no workaround for this vulnerability.
Additional mitigations that can be deployed on Cisco devices within
the network are available in the Cisco Applied Intelligence companion
document fot this advisory:
