vulnerable regardless if a previous patch has been applied due to this security advisory. Customers
running any Cisco Unified CDM Platform Software release should
request the hotfix patch called "ssh_keys_cleanup" through the normal support
channel. The hotfix addresses only the Cisco Unified Communications Domain Manager Default SSH Key Vulnerability.
Cisco Unified Communications Domain Manager BVSMWeb Unauthorized Data Manipulation Vulnerability
This vulnerability affects all Cisco Unified CDM Application Software versions prior to 10
Determining the Running Software Version
The software version for both Cisco Unified CDM Application Software and Platform Software can be determined by accessing the Administration GUI and navigating the About menu options on the top left corner of the page.
Products Confirmed Not Vulnerable
Cisco Unified Communications Manager (Cisco Unified CM) is not affected by these vulnerabilities.
No other Cisco products are currently known to be affected by these vulnerabilities.
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.
CUCDM 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 web framework of the
Cisco Unified Communications Domain Manager Application Software could allow an
authenticated, remote attacker to elevate privileges and gain
administrative access to the affected system.
The vulnerability
is due to improper implementation of authentication and authorization
controls of the Administration GUI. An attacker could exploit this
vulnerability by submitting a crafted URL to change the administrative credentials of a user.
The attacker needs to be authenticated to the system or convince a valid user of the Administration GUI to click a
malicious link.
This vulnerability is documented in Cisco bug ID CSCun49862 (registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2014-2197.
A vulnerability in the implementation of the framework that allows access to
support representatives of the Cisco
Unified Communications Domain Manager Platform Software could allow an unauthenticated,
remote attacker to connect to the affected system with the privileges of
the root user.
The vulnerability is due to the presence of
a default SSH private key, which is stored in an insecure way on the system. An attacker could exploit this vulnerability by obtaining the SSH
private key. For example, the attacker might reverse engineer the binary file of the operating system.
This will allow the attacker to connect by using the support account to the
system without requiring any form of authentication. An exploit could allow the attacker to gain access to the system with the privileges of the root user.
This vulnerability is documented in Cisco bug ID CSCud41130 (registered customers only) and has been assigned CVE ID CVE-2014-2198.
Note: Due to an error in the fix, all Cisco Unified CDM Platform Software releases are
vulnerable regardless if a previous patch has been applied due to this security advisory. Customers
running any Cisco Unified CDM Platform Software release should
request the hotfix patch called "ssh_keys_cleanup" through the normal support
channel. The hotfix addresses only the Cisco Unified Communications Domain Manager Default SSH Key Vulnerability.
The error in the fix is documented in Cisco bug ID CSCuq99452 (registered customers only).
Cisco Unified Communications Domain Manager BVSMWeb Unauthorized Data Manipulation Vulnerability
A vulnerability in the web framework of Cisco Unified Communications Domain Manager Application Software could allow an unauthenticated, remote attacker to access and modify BVSMWeb portal user information such as settings in the personal phone directory, speed dials, Single Number Reach, and call forward settings.
The vulnerability is due to improper implementation of authentication and authorization controls when accessing some web pages of the BVSMWeb portal. An attacker could exploit this vulnerability by submitting a crafted URL to the affected system.
This vulnerability is documented in Cisco bug ID CSCum77041 (registered customers only) and has been assigned CVE ID CVE-2014-3300
Workarounds
There are no workarounds that mitigate the vulnerabilities in this security advisory.
Customers that are affected by the Cisco Unified Communications Domain Manager BVSMWeb Unauthorized Data Manipulation Vulnerability should use the functionality offered by the Cisco Unified Communication Manager and the Cisco Unified CDM Self-Care portal instead of the Cisco Unified CDM BVSMWeb portal to provide services.
When considering software upgrades, customers are advised to consult the Cisco Security Advisories, Responses, and Notices 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.
The Cisco Unified Communications Domain Manager Privilege Escalation Vulnerability is resolved in Cisco Unified CDM Application Software usm-8.1.4-ubuntu10_04.tar.gz and later.
The Cisco Unified Communications Domain Manager Default SSH Key Vulnerability is resolved in Cisco Unified CDM Platform Software hotfix patch called "ssh_keys_cleanup" .
Note: Due to an error in the fix, all Cisco Unified CDM Platform Software releases are
vulnerable regardless if a previous patch has been applied due to this security advisory. Customers
running any Cisco Unified CDM Platform Software release should
request the hotfix patch called "ssh_keys_cleanup" through the normal support
channel. The hotfix addresses only the Cisco Unified Communications Domain Manager Default SSH Key Vulnerability.
Cisco Unified Communications Domain Manager BVSMWeb Unauthorized Data Manipulation Vulnerability
Currently, there is no Cisco Unified CDM version that addresses the Cisco Unified Communications Domain Manager BVSMWeb Unauthorized Data Manipulation Vulnerability. Cisco Unified CDM Application Software version 10 and later does not implement the BVSMWeb service interface and it is not affected by this vulnerability. Cisco Unified CDM version 10 is expected to be available in September 2014. Customers that are concerned about this vulnerability should apply the mitigation detailed in the "Workarounds" section of this advisory until a fixed software release is available.
