Summary

  * 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:

    cisco-sa-20181128-plm-sql-inject

Affected Products

  * 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

  * 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

  * 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 Release patch
    ciscocm.CSCvk30822_v1.0.k3.cop.sgn. 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.

    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 installation of this patch.

    install the patch, is available for download from the Software Center on
    Cisco.com by navigating to:
