Summary
o Update (2018-December-20): The updated patch
ciscocm.CSCvk30822_v2.0.k3.cop.sgn that avoids the functional issues
identified with the v1.0 patch has been posted to Cisco.com. See the Fixed
Releases section for details.
Update (2018-December-10): Installing the
ciscocm.CSCvk30822_v1.0.k3.cop.sgn patch may cause functional issues.
Workarounds are available for some of these issues. Rolling back this patch
as described in the Fixed Releases section will correct these functional
issues, but the device will be affected by this vulnerability again when
the patch is not in place. See the Fixed Releases section for details.
A vulnerability in the web framework code of Cisco Prime License Manager
(PLM) could allow an unauthenticated, remote attacker to execute arbitrary
SQL queries.
The vulnerability is due to a lack of proper validation of user-supplied
input in SQL queries. An attacker could exploit this vulnerability by
sending crafted HTTP POST requests that contain malicious SQL statements to
an affected application. A successful exploit could allow the attacker to
modify and delete arbitrary data in the PLM database or gain shell access
with the privileges of the postgres user.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181128-plm-sql-inject
Affected Products
o Vulnerable Products
This vulnerability affects Cisco Prime License Manager Releases 11.0.1 and
later. Both standalone deployments of Cisco Prime License Manager and
coresident deployments, where Cisco Prime License Manager is installed
automatically as part of the installation of Cisco Unified Communications
Manager and Cisco Unity Connection, are affected.
To identify which release of Cisco Prime License Manager is running,
administrators can log in to the Cisco Prime License Manager GUI and click
About in the top-right corner of the screen. The following example shows
the Version string that is reported by a Cisco Prime License Manager
instance that is running the 11.5.1 release:
Version: 11.5.1.10000-5
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Cisco Unified Communications Manager and Cisco Unity Connection Releases
12.0 and later have been confirmed to be not affected by this vulnerability
as Cisco Prime License Manager is no longer included in these releases.
Workarounds
o There are no workarounds that address this vulnerability.
Customers with coresident deployments of Cisco Prime License Manager as
part of Cisco Unified Communications Manager or Cisco Unity Connection who
do not use PLM can disable the feature to close the attack vector as
follows:
1. Log in to the Cisco Unified Communications Manager or Cisco Unity
Connection CLI as admin user.
2. Run the command license management system remove.
3. Confirm with y.
4. Wait for the operation to complete; afterwards, the system will reboot
automatically.
Note: This procedure needs to be executed on all nodes in a cluster. It
will persist across upgrades.
Fixed Software
o Cisco has released free software updates that address the vulnerability
described in this advisory. Customers may only install and expect support
for software versions and feature sets for which they have purchased a
license. By installing, downloading, accessing, or otherwise using such
software upgrades, customers agree to follow the terms of the Cisco
software license:
https://www.cisco.com/c/en/us/products/end-user-license-agreement.html
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
Cisco Security Advisories and Alerts page, 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.
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:
https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html
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.
Fixed Releases
This vulnerability is fixed in Cisco Prime License Manager patch
ciscocm.CSCvk30822_v2.0.k3.cop.sgn (the v1.0 release of this patch should
no longer be used due to functional issues caused by that version of the
patch). The same COP file can be used with standalone deployments of Cisco
Prime License Manager as well as with coresident deployments as part of
Cisco Unified Communications Manager and Cisco Unity Connection and with
all affected versions. Installation instructions are available in a
corresponding Readme document.
Note: This patch can be installed on Cisco Prime License Manager, Cisco
Unified Communications Manager, and Cisco Unity Connection 11.5(1) only.
Customers running an earlier release will need to upgrade to 11.5(1) prior
to installing this patch.
Functional Issues Identified in the v1.0 Patch File
Installing the ciscocm.CSCvk30822_v1.0.k3.cop.sgn patch on standalone or
coresident PLM will resolve the vulnerability described in this advisory,
but this action will disable the following features:
o Install/upgrade functionality in the PLM GUI
o Backup and Restore functionality in the PLM GUI
Workarounds for the Functional Issues
Standalone PLM
o Install/upgrade can be accomplished by using the CLI.
o There is no workaround for the Backup and Restore functionality.
Coresident PLM
o Install/upgrade can be accomplished by using the CUCM/CUC GUI.
o Backup and Restore functionality continues to be available in the CUCM/
CUC GUI.
Upgrading from the v1.0 Patch to the v2.0 Patch
Customers who have previously installed the
ciscocm.CSCvk30822_v1.0.k3.cop.sgn patch should upgrade to the
ciscocm.CSCvk30822_v2.0.k3.cop.sgn patch to remediate the functional
issues. Installing the v2.0 patch will first rollback the v1.0 patch and
then install the v2.0 patch:
o Download the ciscocm.CSCvk30822_v2.0.k3.cop.sgn file from the locations
indicated in the Patch and Patch Rollback File Download section of this
advisory.
o Install that downloaded file by using the CLI (for a standalone PLM) or
by using the CUCM/CUC GUI (for a coresident PLM).
