The vulnerability is due to insufficient input validation of certain parameters that are passed to the affected software via the HTTP GET and HTTP POST methods. An attacker who can convince a user to follow an attacker-supplied link could execute arbitrary script or HTML code in the user?s browser in the context of an affected site.

The vulnerability is due to incomplete input validation of the client EAP-TLS certificate. An attacker could exploit this vulnerability by initiating EAP authentication over TLS to the ISE with a crafted EAP-TLS certificate. A successful exploit could allow the attacker to restart the ISE application server, resulting in a DoS condition on the affected system. The ISE application could continue to restart while the client attempts to establish the EAP authentication connection. If an attacker attempted to import the same EAP-TLS certificate to the ISE trust store, it could trigger a DoS condition on the affected system. This exploit vector would require the attacker to have valid administrator credentials. 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-20180516-iseeap Affected Products o Vulnerable Products The vulnerability affects the following Cisco ISE products: o Cisco ISE o Cisco ISE Express o Cisco ISE Virtual Appliance To determine which release of the software is currently running on a device, administrators may use the show version command in the device CLI or navigate to the top-right corner and click Settings (gear icon) > About Identity Service Engine in the Admin portal. The output of the command in the CLI is similar to the following example: ServiceEngine115/admin# show version Cisco Application Deployment Engine OS Release: 2.3 ADE-OS Build Version: 2.3.0.187 ADE-OS System Architecture: x86_64 Copyright (c) 2005-2014 by Cisco Systems, Inc.

Cisco has confirmed that this vulnerability does not affect Cisco ISE Passive Identity Connector. Workarounds o There are no workarounds that address this vulnerability. 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.
