[guru] [psirt@cisco.com: Cisco Security Advisory: Multiple Vulnerabilities in Cisco Security Monitoring, Analysis and Response System (CS-MARS)]
DATE: Thu, 10 Aug 2006 12:30:43 +0200
Több biztonsági hibát találtak a Cisco Security Monitoring, Analysis and
Response System-ben.
o A CS-MARS Oracle adatbázissal szállított, mely több defult Oracle
accounttal rendelkezik, melyek jelszava jól ismert;
o A CS-MARS tartalmaz JBoss web applikációs szervert is. A JBoss egy
hibájának kihasználásával a távoli nem authentikált támadó tetszőleges
shell kódot futtathat a CS-MARS adminisztrátor jogaival;
o A CS-MARS CLI több hibát tartalmaz, melyek kihasználása az
authentikált adminisztrátor tetszőleges shell parancsot futtathat root
jogokkal.
A javítás elérhető.

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

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
