CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:X/RL:X/RC:X CVE-2017-12337 CWE-287 Download CVRF Download PDF Email Summary



The vulnerability occurs when a refresh upgrade or Prime Collaboration Deployment (PCD) migration is performed on an affected device. When a refresh upgrade or PCD migration is completed successfully, an engineering flag remains enabled and could allow root access to the device with a known password.



If the vulnerable device is subsequently upgraded using the standard upgrade method to an Engineering Special Release, service update, or a new major release of the affected product, this vulnerability is remediated by that action.



Note: Engineering Special Releases that are installed as COP files, as opposed to the standard upgrade method, do not remediate this vulnerability.



An attacker who can access an affected device over SFTP while it is in a vulnerable state could gain root access to the device. This access could allow the attacker to compromise the affected system completely.



Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

There are no workarounds that address this vulnerability.This advisory is available at the following link: Affected Products Vulnerable Products

Cisco Unified Communications Manager (UCM) Cisco Unified Communication Manager Session Management Edition (SME) Cisco Emergency Responder Cisco Unity Connection Cisco Unified Communications Manager IM and Presence Service (IM&P; earlier releases were known as Cisco Unified Presence) Cisco Prime License Manager Cisco Hosted Collaboration Mediation Fulfillment Cisco Unified Contact Center Express (UCCx) Cisco SocialMiner Cisco Unified Intelligence Center (UIC) Cisco Finesse Cisco MediaSense The PCD migration method affects only Cisco UCM, SME, and IM&P.

Determining the Upgrade or Migration Method The Cisco VOS-based products identified in the preceding vulnerable products list are affected by this vulnerability if they were refresh upgraded or migrated by using the PCD methods. Note that a VOS-based product must go through a refresh upgrade if the underlying operating system is also being upgraded to a new major release.



If the VOS-based product was standard upgraded to an Engineering Special, service update, or a new major release of the affected product that does not require major upgrades to the underlying operating system, this vulnerability will be remediated by that standard upgrade action.



Refresh Upgrade Method Verification



To verify whether the product has been exposed to the vulnerability by the refresh upgrade method, issue the following command at the CLI to view the system-history.log file:

admin: file view install system-history.log

The following example shows a refresh upgrade entry in the system-history.log file:

02/28/2013 14:56:05 | root: Upgrade (refresh) 10.0.0.97016-27 Success

The following example shows a standard upgrade entry in the system-history.log file:

10/13/2017 18:56:07 | root: Upgrade 12.0.1.20000-3 Success

PCD Migration Method Verification



To verify whether the product has been exposed to this vulnerability by the PCD migration method, issue the following command at the CLI to view the install.log file:

admin: file view install install.log

The following example shows a PCD migration log entry in the install.log file:

10/16/2017 13:59:13 post_install|Starting post_install processing - VOS_INSTALL_CONTEXT = M1|

The following example shows a normal fresh install log entry in the install.log file:

08/15/2011 08:56:03 post_install|Starting post_install processing - VOS_INSTALL_CONTEXT = install|

Underlying Operating System Upgraded to a New Major Release



A VOS-based product will undergo a refresh upgrade if the underlying operating system is also upgraded to a new major release.



The following examples show major operating system releases that are associated with major affected product releases:



Cisco UCM, Cisco Unity Connection, and Cisco Unified Presence Server/Cisco IM&P Major Release Operating System Major Release 8.6 RHEL 5 Update 5 9.x RHEL 5 Update 7 10.x RHEL 6 Update 2 11.x RHEL 6 Update 5 12.x CentOS 6 Update 6

Because an upgrade from RHEL 6 to CentOS 6 is not considered a major operating system release change, product updates between these operating system releases will use the standard upgrade method.



Prime Collaboration Deployment Cluster Migration



Prime Collaboration Deployment is a free application that is designed to assist in the management of various Cisco Unified Communications applications. The PCD migrate cluster task is supported only for the following Cisco products and to only certain cluster migration destination versions.

UCM destination version 10.x, 11.0(1), 11.5(x), 12.0(1) IM&P destination version 10.x, 11.0(1), 11.5(x), 12.0(1)

Refer to the product documentation for information about specific upgrade and migration methods. Determining the Current Software Release for the Cisco Unified Platform The following Cisco products run on the Cisco Unified platform:

Unified Communications Manager Unified Communications Manager Session Management Edition Emergency Responder Unity Connection Unified Communications Manager IM and Presence Service Prime License Manager Hosted Collaboration Mediation Fulfillment

To determine which Cisco VOS-based product software release is running on the Cisco Unified platform, an administrator can issue the show version active command at the CLI.



In the following example, the software release is 11.5.1.10000-86.

ciscocm: show version active Active Master Version: 11.5.1.10000-86

An administrator can use the user interface to determine which Cisco VOS-based product software release is running:

Log in to the web-based interface Click the Help menu Click About to view the system software release

Determining the Current Software Release for the Cisco Contact Center Platform The following Cisco products run on the Cisco Contact Center platform: Unified Contact Center Express SocialMiner Unified Intelligence Center Finesse MediaSense

To determine which Cisco VOS-based product software release is running on the Contact Center platform, an administrator can issue the show version active command at the CLI.



In the following example, the software release is 11.5.1.10000-86.

admin: show version active Active Master Version: 11.5.1.10000-86

An administrator can use the user interface to determine which Cisco Contact Center platform–based product software release is running:

Log in to the Contact Center Express server Go to the Cisco Unified Communications operating system administration window Choose Show > Software

Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.



When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the



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.



Customers Without Service Contracts Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC:
