Summary

• A vulnerability in the web-based management interface of Cisco Prime Service Catalog Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.

  The vulnerability is due to insufficient CSRF protection mechanisms on the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user.

  Cisco has released software updates that address this vulnerability. There are workarounds that address this vulnerability.

Affected Products

• Vulnerable Products

  This vulnerability applies to all Cisco Prime Service Catalog Software releases prior to 12.1 Cumulative patch version 10.

  Products Confirmed Not Vulnerable

  Only products listed in the Vulnerable Products section of this advisory are known to be affected by this vulnerability.

Details

• More information can be found in "Understanding Cross-Site Request Forgery Threat Vectors" at https://sec.cloudapps.cisco.com/security/center/viewAMBAlert.x?alertId=28726.

Workarounds

• A workaround is only available for software releases after 11.1.1 Cumulative patch version 11. For those, extra CSRF protection mechanisms can be enabled by adding the line session.token.validation=1 to the RequestCenter.war/WEB-INF/classes/config/newscale.properties configuration file.

  There is no workaround available prior to software release 11.1.1 Cumulative patch version 11.

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 Service Catalog Release 12.1 Cumulative patch version 10 and later releases.
