==================================================================== CERT-Renater Note d'Information No. 2015/VULN127 _____________________________________________________________________ DATE : 03/07/2015 HARDWARE PLATFORM(S): / OPERATING SYSTEM(S): Systems running Cisco Unified Communications Domain Manager versions prior to 4.4.5. ====================================================================== http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20150701-cucdm ______________________________________________________________________ Cisco Security Advisory Cisco Unified Communications Domain Manager Default Static Privileged Account Credentials Advisory ID: cisco-sa-20150701-cucdm http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20150701-cucdm Revision 1.0 For Public Release 2015 July 1 16:00 UTC (GMT) Summary A vulnerability in the Cisco Unified Communications Domain Manager Platform Software could allow an unauthenticated, remote attacker to login with the privileges of the root user and take full control of the affected system. The vulnerability occurs because a privileged account has a default and static password. This account is created at installation and cannot be changed or deleted without impacting the functionality of the system. An attacker could exploit this vulnerability by remotely connecting to the affected system via SSH using this account. An exploit could allow the attacker to take full control over the affected system. Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are not available. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20150701-cucdm Affected Products Vulnerable Products Releases prior to 4.4.5 of Cisco Unified Communications Domain Manager Platform Software for Cisco Unified Communications Domain Manager version 8.x are affected by this vulnerability. Cisco Unified Communications Domain Manager version 10.x is not affected by this vulnerability because it does not contain the affected platform software. Products Confirmed Not Vulnerable Cisco Unified Communications Manager (Cisco Unified CM) is not affected by this vulnerability. No other Cisco products are currently known to be affected by this vulnerability. Details Cisco Unified Communications Domain Manager (Cisco Unified CDM) is a service delivery and management platform that provides automation and administrative functions over the Cisco Unified Communications Manager, Cisco Unity Connection, and Cisco Jabber applications, as well as the associated phones and soft clients. Cisco Unified CDM is part of Cisco Hosted Collaboration System (HCS). The Cisco Unified CDM solution includes an application software and a platform software. A vulnerability in the Cisco Unified Communications Domain Manager Platform Software could allow an unauthenticated, remote attacker to login with the privileges of the root user and take full control of the affected system. The vulnerability occurs because a privileged account has a default and static password. This account is created at installation and cannot be changed or deleted without impacting the functionality of the system. An attacker could exploit this vulnerability by remotely connecting to the affected system via SSH using this account. An exploit could allow the attacker to take full control of the affected system. This vulnerability is documented in Cisco bug ID CSCuq45546 (registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2015-4196. Vulnerability Scoring Details Cisco has scored the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response. Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks. Cisco has provided additional information regarding CVSS at the following link: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link: http://intellishield.cisco.com/security/alertmanager/cvss CSCuq45546 - Cisco Unified Communications Domain Manager Default Static Privileged Account Credentials Calculate the environmental score of CSCuq45546 CVSS Base Score - 10.0 Access Access Authentication Confidentiality Integrity Availability Vector Complexity Impact Impact Impact Network Low None Complete Complete Complete CVSS Temporal Score - 8.7 Exploitability Remediation Level Report Confidence High Official-Fix Confirmed Impact Successful exploitation of the vulnerability may allow a remote attacker to log in with a privileged account and take full control of the system. Software Versions and Fixes When considering software upgrades, customers are advised to consult the Cisco Security Advisories, Responses, and Alerts archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. This vulnerability has been resolved in Cisco Unified Communications Domain Manager Platform Software Releases 4.4.5 and later. Customers running Cisco Unified Communications Domain Manager Platform Software Releases 4.4.3 and 4.4.4 can request a hotfix patch through their normal support channels. Workarounds There are no workarounds that mitigate this vulnerability. Obtaining Fixed Software Cisco has released free software updates that address the vulnerability described in this advisory. Prior to deploying software, customers are advised to consult their maintenance providers or check the software for feature set compatibility and known issues that are specific to their environments. Customers may only install and expect support for feature sets they have purchased. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html. Customers with Service Contracts Customers with contracts should obtain upgraded software through their regular update channels. For most customers, upgrades should be obtained through the Software Navigator on Cisco.com at http://www.cisco.com/cisco/software/navigator.html. Customers Using Third-Party Support Organizations Customers with Cisco products that 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 organization for assistance with the appropriate course of action. The effectiveness of any workaround or fix depends on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Because of the variety of affected products and releases, customers should consult their service providers or support organizations to ensure that any applied workaround or fix is the most appropriate in the intended network before it is deployed. Customers Without Service Contracts Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through Cisco Authorized partners, resellers, and distributors (authorized third-party vendors) but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco Technical Assistance Center (TAC): +1 800 553 2447 (toll free from within North America) +1 408 526 7209 (toll call from anywhere in the world) email: tac@cisco.com Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade. Customers without service contracts should request free upgrades through the TAC.
