Summary
=======
Cisco Security Monitoring, Analysis and Response System (CS-MARS)
software contains vulnerabilities related to third-party software and
the command line interface (CLI).
* CS-MARS ships with an Oracle database. The database contains
several default Oracle accounts which have well-known passwords. If
access to the database is obtained, the default accounts may be
used to access sensitive information contained in the database.
* CS-MARS ships with the JBoss web application server. A component of
the JBoss installation may allow a remote, unauthenticated user to
execute arbitrary shell commands with the privileges of the CS-MARS
administrator.
* The CS-MARS CLI contains several vulnerabilities which may allow
authenticated administrators to execute arbitrary shell commands
with root privileges.
All vulnerabilities addressed in this advisory have been corrected in
CS-MARS software version 4.2.1.
Cisco has made free software available to address these vulnerabilities
for affected customers. There are no workarounds.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20060719-mars.shtml.
Affected Products
=================
Vulnerable Products
+------------------
CS-MARS software versions prior to 4.2.1 are affected by
vulnerabilities addressed in this advisory.
To verify the version of CS-MARS software, use a SSH client to login
into the system administration command line interface with the pnadmin
account and execute the version command.
prompt$ ssh pnadmin at 10.0.0.1
pnadmin at 10.0.0.1's password:

Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected these
vulnerabilities.
Details
=======
Cisco Security Monitoring, Analysis and Response System (CS-MARS) is a
security system that receives event logs from various network devices,
correlates and analyzes the received data for security problems and
reports the findings. In addition, CS-MARS can perform automated tasks
to mitigate security problems.
* CS-MARS utilizes an Oracle database to store sensitive network
event and configuration data. The information contained in the
database potentially includes authentication credentials for
network devices such as firewalls, routers and IPS devices and the
details of network security events. By default, Oracle databases
contain several built-in accounts with well-known passwords. If
access can be gained to the database, the accounts could
potentially be used to compromise the information stored in the
database. The CS-MARS appliance is hardened to prevent local and
remote unauthorized access to the database. As a precaution, the
database accounts have been disabled by Cisco to prevent abuse
should a method to access the database be discovered. The CS-MARS
application does not use the default Oracle database accounts. This
vulnerability is documented by Cisco bug ID CSCsd16256.
* CS-MARS contains an installation of the JBoss web application
server. It may be possible for a remote, unauthenticated user to
create a specially-crafted HTTP request which executes arbitrary
shell commands on the CS-MARS appliance with the privileges of the
CS-MARS administrator via the optional JBoss JMX console. This
vulnerability is documented by Cisco bug ID CSCse47646.
* The CS-MARS CLI is a restricted shell environment which allows
authenticated administrators to perform system maintenance tasks.
The CLI contains several privilege escalation vulnerabilities which
may allow shell commands to be executed on the underlying appliance
operating system with root privileges. These vulnerabilities are
documented by Cisco bug IDs CSCsd29111, CSCsd31371, CSCsd31377,
CSCsd31392 and CSCsd31972.
Impact
======
* Exploitation of the default Oracle accounts vulnerability (CSCsd16256)
may result in the compromise of sensitive information contained in
the CS-MARS database.
* Exploitation of the JBoss command execution vulnerability (CSCse47646)
may allow a remote unauthenticated user to execute arbitrary
shell commands with the privileges of the CS-MARS administrator.
* Exploitation of the CLI command execution vulnerabilities (CSCsd29111,
CSCsd31371, CSCsd31377, CSCsd31392 and CSCsd31972) may allow an
authenticated administrator to execute arbitrary shell commands with
root privileges.
Software Version 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.
CS-MARS versions 4.2.1 and later contain the fixes for all
vulnerabilities referenced in this advisory.
CS-MARS upgrades are incremental. All available updates must be applied
in order to reach the most recent version. The upgrade path is
documented at:
http://www.cisco.com/univercd/cc/td/doc/product/vpn/ciscosec/mars/4_2/rn420.htm#wp1136717
CS-MARS software updates can be obtained at the following site:

Workarounds
===========
There are no workarounds for these vulnerabilities.
Obtaining Fixed Software
========================
Cisco will make free software available to address this vulnerability
for affected customers. This advisory will be updated as fixed software
becomes available. Prior to deploying software, customers should
consult their maintenance provider or check the software for feature
set compatibility and known issues specific to their environment.
Customers may only install and expect support for the feature sets they
have purchased. By installing, downloading, accessing or otherwise
using such software upgrades, customers agree to be bound by the terms
of Cisco's software license terms found at
http://www.cisco.com/public/sw-license-agreement.html , or as otherwise
set forth at Cisco.com Downloads at
http://www.cisco.com/public/sw-center/sw-usingswc.shtml.
Do not contact either "psirt at cisco.com" or "security-alert at cisco.com"
for software upgrades.
Customers with Service Contracts
+-------------------------------
Customers with contracts should obtain upgraded software through their
regular update channels. For most customers, this means that upgrades
should be obtained through the Software Center on Cisco's worldwide
website at http://www.cisco.com .
Customers using Third Party Support Organizations
+------------------------------------------------
Customers whose Cisco products are provided or maintained through prior
or existing agreement with third-party support organizations such as
Cisco Partners, authorized resellers, or service providers should
contact that support organization for guidance and assistance with the
appropriate course of action in regards to this advisory.
The effectiveness of any workaround or fix is dependent on specific
customer situations such as product mix, network topology, traffic
behavior, and organizational mission. Due to the variety of affected
products and releases, customers should consult with their service
provider or support organization to ensure any applied workaround or
fix is the most appropriate for use in the intended network before it
is deployed.
Customers without Service Contracts
+----------------------------------
Customers who purchase direct from Cisco but who do not hold a Cisco
service contract and customers who purchase through third-party vendors
but are unsuccessful at obtaining fixed software through their point of
sale should get their upgrades by contacting the Cisco Technical
Assistance Center (TAC). TAC contacts are as follows.
* +1 800 553 2447 (toll free from within North America)
* +1 408 526 7209 (toll call from anywhere in the world)
* e-mail: tac at cisco.com
Have your product serial number available and give the URL of this
notice as evidence of your entitlement to a free upgrade. Free upgrades
for non-contract customers must be requested through the TAC.
Refer to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
for additional TAC contact information, including special localized
telephone numbers and instructions and e-mail addresses for use in
various languages.
