VAR-201106-0024

Vulnerability from variot - Updated: 2025-04-11 22:54

Cisco Media Processing Software before 1.2 on Media Experience Engine (MXE) 5600 devices has a default root password, which makes it easier for context-dependent attackers to obtain access via (1) the local console, (2) an SSH session, or (3) a TELNET session, aka Bug ID CSCto77737. The Cisco MXE 5600 includes a root account for advanced debugging, but is not required for normal operations. The root account is different from the admin and user accounts. If Telnet is enabled, it can also be accessed via Telnet. An attacker can exploit this issue to gain unauthorized administrative access to the affected device. Successful exploits will result in the complete compromise of the affected device. This issue is being tracked by Cisco bug ID CSCto77737. A software upgrade is not required to resolve this vulnerability. Customers can change the root account password by issuing a configuration command on affected engines. The workarounds detailed in this document provide instructions for changing the root account password. To determine the software release that is running on a Cisco MXE unit, log in to the device and issue the show version command-line interface (CLI) command to display the system banner. The following example shows a Cisco MXE 5600 device running software version 1.2.0-34.

No other Cisco products are currently known to be affected by this vulnerability. For instructions on how to set or change the root password, see the Workarounds section of this advisory.

Vulnerability Scoring Details

Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0.

CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response.

Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks.

Cisco has provided an FAQ to answer additional questions regarding CVSS at:

http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html

Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at:

http://intellishield.cisco.com/security/alertmanager/cvss

CSCto77737 ("Default Credentials for root Account on MXE 5600")

CVSS Base Score - 10.0 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete

CVSS Temporal Score - 8.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed

Impact

Successful exploitation of the vulnerability may allow an unauthorized user to modify the software configuration and the operating system settings or gain complete administrative control of the device.

Software Versions 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. The passwd command will accept a null or weak password, but Cisco highly recommends using a long, complex password. To change the password, users will need the default password. To obtain the default password, customers must contact the Cisco TAC. Because entitlement will be verified, please have the product serial number available and refer to this advisory.

Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Intelligence companion document for this advisory:

Obtaining Fixed Software

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/en/US/docs/general/warranty/English/EU1KEN_.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml.

Do not contact 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 agreements 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 +----------------------------------

Cisco will not make free upgrade software available for affected customers to address this vulnerability. The workaround provided in this document describes how to change the passwords in current releases of the software.

The CVSS\nscoring in this Security Advisory is done in accordance with CVSS\nversion 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n\n* CSCto77737 (\"Default Credentials for root Account on MXE 5600\")\n\nCVSS Base Score - 10.0\n    Access Vector -            Network\n    Access Complexity -        Low\n    Authentication -           None\n    Confidentiality Impact -   Complete\n    Integrity Impact -         Complete\n    Availability Impact -      Complete\n\nCVSS Temporal Score - 8.3\n    Exploitability -           Functional\n    Remediation Level -        Official-Fix\n    Report Confidence -        Confirmed\n\n\nImpact\n======\n\nSuccessful exploitation of the vulnerability may allow an\nunauthorized user to modify the software configuration and the\noperating system settings or gain complete administrative control of\nthe device. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult\nhttp://www.cisco.com/go/psirt and any subsequent advisories to determine\nexposure and a complete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. The passwd command will accept a null or weak password, but\nCisco highly recommends using a long, complex password. To change the\npassword, users will need the default password. To obtain the default\npassword, customers must contact the Cisco TAC. Because entitlement\nwill be verified, please have the product serial number available and\nrefer to this advisory. \n\nAdditional mitigations that can be deployed on Cisco devices within\nthe network are available in the Cisco Applied Intelligence companion\ndocument for this advisory:\n\nhttp://www.cisco.com/warp/public/707/cisco-amb-20110601-mxe.shtml\n\nObtaining Fixed Software\n========================\n\nPrior to deploying software, customers should consult their\nmaintenance provider or check the software for feature set\ncompatibility and known issues specific to their environment. \n\nCustomers may only install and expect support for the feature\nsets they have purchased. By installing, downloading, accessing\nor otherwise using such software upgrades, customers agree to be\nbound by the terms of Cisco\u0027s software license terms found at\nhttp://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html,\nor as otherwise set forth at Cisco.com Downloads at\nhttp://www.cisco.com/public/sw-center/sw-usingswc.shtml. \n\nDo not contact psirt@cisco.com or security-alert@cisco.com for\nsoftware upgrades. \n\nCustomers with Service Contracts\n+-------------------------------\n\nCustomers with contracts should obtain upgraded software through\ntheir regular update channels. For most customers, this means that\nupgrades should be obtained through the Software Center on Cisco\u0027s\nworldwide website at http://www.cisco.com. \n\nCustomers using Third Party Support Organizations\n+------------------------------------------------\n\nCustomers whose Cisco products are provided or maintained through\nprior or existing agreements with third-party support organizations,\nsuch as Cisco Partners, authorized resellers, or service providers\nshould contact that support organization for guidance and assistance\nwith the appropriate course of action in regards to this advisory. \n\nThe effectiveness of any workaround or fix is dependent on specific\ncustomer situations, such as product mix, network topology, traffic\nbehavior, and organizational mission. Due to the variety of affected\nproducts and releases, customers should consult with their service\nprovider or support organization to ensure any applied workaround or\nfix is the most appropriate for use in the intended network before it\nis deployed. \n\nCustomers without Service Contracts\n+----------------------------------\n\nCisco will not make free upgrade software available for affected\ncustomers to address this vulnerability. The workaround provided in\nthis document describes how to change the passwords in current\nreleases of the software. \n\nExploitation and Public Announcements\n=====================================\n\nThe Cisco PSIRT is not aware of any public announcements or malicious\nuse of the vulnerability described in this advisory. \n\nThis vulnerability was discovered during internal testing. \n\nStatus of this Notice: FINAL\n============================\n\nTHIS DOCUMENT IS PROVIDED ON AN \"AS IS\" BASIS AND DOES NOT IMPLY ANY\nKIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTIES OF\nMERCHANTABILITY OR FITNESS FOR A PARTICULAR USE.
