Cisco Policy Suite Release 14.0.0 is also affected, as it includes vulnerable code, but RADIUS authentication is not officially supported in Cisco Policy Suite Releases 14.0.0 and later. See the Fixed Software [\"#Fixed\"] section of this security advisory for additional information about the affected software versions.\r\n\r\nTo determine which software version is running on the application, administrators can issue the about.sh command from the CLI. In the following example, the device is running software release 12.1.0:\r\n# about.sh\r\nCisco Policy Suite - Copyright (c) 2015.

RADIUS authentication is not enabled by default. Administrators can use the Policy Builder GUI to verify if RADIUS authentication is configured for a domain by accessing the Services tab and selecting the appropriate domain under the Domains tab. On the General tab, administrators can check if USuM Authorization is selected and the User Id Field and Password Field are populated with RADIUS Username and RADIUS Password respectively.",

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:\r\nhttps://www.cisco.com/c/en/us/products/end-user-license-agreement.html [\"https://www.cisco.com/c/en/us/products/end-user-license-agreement.html\"]\r\n\r\nAdditionally, 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.\r\n\r\nWhen 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 [\"https://www.cisco.com/go/psirt\"], to determine exposure and a complete upgrade solution.\r\n\r\nIn 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.\r\n\r\nCustomers Without Service Contracts\r\n\r\nCustomers 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:\r\nhttps://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html [\"https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html\"]\r\n\r\nCustomers 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.\r\n\r\nFixed Releases\r\n\r\nIn the following table, the left column lists major releases of Cisco Policy Suite software. The right column indicates whether a major release is affected by the vulnerability described in this advisory and the first minor release that includes the fix for this vulnerability.\r\n\r\nCustomers should upgrade to an appropriate release as indicated in the following table:\r\n                            Cisco Policy Suite Major Release                          First Fixed Release for This Vulnerability                               Prior 12.x\r\n             Vulnerable.
