Advisory ID: cisco-sa-20060719-marsRevision 1.0
For Public Release 2006 July 19 16:00 UTC (GMT)
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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20060719-mars.
This section provides details on affected 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 an SSH client to login
into the system administration command line interface with the
pnadmin account and execute the version
command.
prompt$ ssh pnadmin@10.0.0.1
pnadmin@10.0.0.1's password:

No other Cisco products are currently known to be affected these
vulnerabilities.
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
(
registered customers only)
.
-
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
(
registered customers only)
.
-
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
(
registered customers only)
,
CSCsd31371
(
registered customers only)
,
CSCsd31377
(

,
CSCsd31392
(

and
CSCsd31972
(

.
This section describes the impact of these vulnerabilities.
-
Exploitation of the default Oracle accounts vulnerability (CSCsd16256
(
registered customers only)
) may result in the compromise of
sensitive information contained in the CS-MARS database.
-
Exploitation of the JBoss command execution vulnerability (CSCse47646
(
registered customers only)
) 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
(
registered customers only)
,
CSCsd31371
(
registered customers only)
,
CSCsd31377
(
registered customers only)
,
CSCsd31392
(
registered customers only)
and
CSCsd31972
(
registered customers only)
) may allow an authenticated administrator
to execute arbitrary shell commands with root privileges.
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
