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 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
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.
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:
Note: This procedure needs to be executed on all nodes in a cluster. It will persist across upgrades.
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 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.
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:
Workarounds for the Functional Issues
Standalone PLMUpgrading 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:
