Compaq Management Software Security Vulnerability (SSRT0758)

*Reference SSRT0758*
PATCHES SUPERSEDED BY THIS ADVISORY:
The software upgrades and patches also fix all previous
Compaq Management Software security vulnerabilities
reported in the following Compaq Security Advisories:
* Compaq Management Software Security Vulnerability - SSRT0715
(March, 2001)
* Compaq Web-enabled Management Software Security Vulnerability
- SSRT0705 (January 2001)
SUMMARY
Compaq Management Software products undergo rigorous quality
assurance processes to ensure that they meet the highest possible
standards for security, reliability and usability. In line with
this commitment, Compaq recently uncovered a potential buffer
overflow security vulnerability in its Web-enabled Management
Software. This vulnerability has the potential to enable unauthorized
users to execute code at an administrator level through the
exploitation of a buffer overflow. Compaq has addressed this
issue with version 5.2 of the Compaq Management Agents and developed
a patch that may be downloaded from the Compaq website (see details
below) to fix existing Agents installations.
Compaq strongly recommends that customers upgrade to
version 5.2 of the Compaq Management Agents or apply
the appropriate patch.
Compaq strongly recommends that web-enabled agents and utilities
be deployed only on private networks and are not used on the open
Internet or on systems outside the bounds of the firewall. The
implementation of sound security practices, which includes disabling
external access to Compaq management ports should help to protect
customers from external malicious attacks. Compaq also recommends
that strong password standards are used and that passwords are
changed regularly.
NOTE: The complete online document is available from
http://www.compaq.com/manage/security and should be
checked frequently for new patch release information.
If a TBD is entered for a product, please contact your
normal Compaq support channel to inquire about a
specific product solution status.
SCOPE OF THE PROBLEM
The web component of Compaq web-enabled management software provides
HTTP services to allow management information to be accessible
through a web browser. Web-enabled management software is provided
for the majority of the operating systems that Compaq supports on
its Intel-based and Alpha-based server and client systems. These
operating systems include Microsoft Windows 9x, Windows NT and
Windows 2000, Novell NetWare, SCO UnixWare 7, Red Hat Linux 6.2
and 7.0, SuSE Linux 7.0 & 7.1, Tru64 Unix and Open VMS. Web-enabled
management software is also supported for Compaq storage products.
This Security Advisory applies to all Compaq Web-enabled Management
Software. A list of affected software versions is available at
http://www.compaq.com/products/servers/management/mgtsw-advisory2.html
(note the url above may wrap unintentionally)
UNAFFECTED SOFTWARE VERSIONS
The web-enabled component of the Compaq Remote Insight Lights-Out
Edition board is NOT affected. Also unaffected are the downloadable
integration modules that Compaq provides to enhance the management
of Compaq platforms from within enterprise management consoles such
as CA Unicenter TNG, Tivoli Enterprise, Tivoli NetView, and HP
OpenView.
WHAT COMPAQ IS DOING
Compaq is currently completing the testing and release of fixes
for the affected software. Compaq Management CD Version 5.2 includes
an update that fixes the buffer overflow security vulnerability issue
in some Compaq Web-enabled Management Software. In addition to
releasing new versions of the software, Compaq will also
release software patches to update existing versions of
the web-enabled management software.
Three patches are now available for download from:
ftp://ftp.compaq.com/pub/softpaq/sp17501-18000/
SoftPaq SP 17926 fixes the problem for affected versions of Compaq
Foundation Agents for Windows Servers, Compaq Survey for Windows,
Compaq Power Manager, Compaq Intelligent Cluster Administrator,
and Compaq Availability Agents. This patch also fixes the problem
for the SNMP and DMI agents installed with Compaq Insight Manager
XE Version 2.0 and 2.1. Compaq recommends applying the patch if
any of the Compaq Management Software mentioned above is
installed.
SoftPaq SP 17927 fixes the problem for affected versions of the
Compaq Foundation Agents for Novell NetWare servers.
SoftPaq SP 17928 fixes the problem for affected versions of the
Compaq Foundation Agents for Linux servers
Compaq Security Advisory SSRT0758 will be updated as needed to
communicate availability and plans for new versions of all
the affected software.
WHAT CUSTOMERS SHOULD DO
Determine which systems are running Compaq web-enabled agents or
utilities. There are three methods suggested.
Method 1
Point a web browser to the system by keying in
http://[IP_ADDRESS]: 2301 or http://[machine_name]:2301.
This will bring up the device home page for any servers running
web-enabled management software, and display a list of the
components.
NOTE: The lists generated by Methods 2 and 3, while helpful, may
not be exhaustive lists of the systems with web-enabled agents and
utilities. The lists will include only those systems that are being
managed either explicitly or because they have been discovered.
Method 2
Systems running Compaq Insight Manager XE, can get a list of systems
running the web-enabled agents by defining a Query to return a list
of systems with web agents.
Login to your Compaq Insight Manager XE system and create a new
Query. Select the "Devices with Web Agent" criteria.
- - - - - Select all of the available products on the Criteria
Configuration
screen.
- - - - - Save the Query and execute it.
The list of devices will be all those with web agents.
Method 3
Systems running Compaq Insight Manager Windows 32 console, can get a
list of systems running the web agents by starting Compaq Insight
Manager and selecting the "Web Device List" button on the toolbar.
This will display a list of systems being managed by Compaq
Insight Manager and additionally will have underlined as
hyperlinks the systems on which the web agents are present
and enabled. To print out a list of only the web devices,
select the "Web Devices" hyperlink in the left column and
only web devices will be shown. Print this page from your
browser.
If for any reason the software cannot be updated or the patch
applied, Compaq recommends that the web-enabled components
of Compaq Management Software be temporarily disabled;
by following the procedures outlined at the end of this
advisory.
Compaq has always advised that web-enabled agents and utilities be
deployed only in private networks and not used on the Internet or on
systems outside the bounds of a firewall. Verify that you have
disallowed access to non-essential IP ports on your firewall or proxy
protecting the corporate network from the Internet. The disabling of
such ports, which include port 2301 (Device Management Port) and port
280 (Compaq Insight Manager XE port), is part of a sound security
policy for your network.
HOW DO I OBTAIN THE UPDATED COMPAQ MANAGEMENT SOFTWARE OR PATCH?
Updated software will be made available on the web through the system
software download site
(
http://www.compaq.com/support/files/server/us/index.html) and will
also be proactively delivered directly to customers who have
installed Compaq ActiveUpdate. ). Compaq recommends registering for
the ActiveUpdate service, which is available at the following
URL:
http://www.compaq.com/activeupdate.
