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@10.0.0.1 pnadmin@10.0.0.1's password: Last login: Tue Jun 20 16:22:34 2006 from 10.0.0.2 CS MARS - Mitigation and Response System ? for list of commands [pnadmin]$ version 4.1.5 (2198)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 ( 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 ( registered customers only) , CSCsd31392 ( registered customers only) and CSCsd31972 ( registered customers only) . Impact 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. 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: /en/US/products/ps6241/prod_release_note09186a008066e320.html#wp1136717 CS-MARS software updates can be obtained at the following site: http://www.cisco.com/pcgi-bin/tablebuild.pl/cs-mars?psrtdcat20e2 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@cisco.com" or "security-alert@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@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.
