Cisco Identity Services Engine Cross-Site Scripting Vulnerability

Severity: Medium
Advisory ID: cisco-sa-20180516-ident-se-xss
First Published: 2018 May 16 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvg86743

CVSS Score:
Base 6.1
CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X
CVE-2018-0327
 

Summary

  * 
    A vulnerability in the web framework of Cisco Identity Services Engine
    (ISE) could allow an unauthenticated, remote attacker to conduct a
    cross-site scripting (XSS) attack against a user of the web interface of an
    affected system.

    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.

    There are no workarounds that address this vulnerability.

Cisco Identity Services Engine EAP TLS Certificate Denial of Service
Vulnerability

Severity: High
Advisory ID: cisco-sa-20180516-iseeap
First Published: 2018 May 16 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCve31857

CVSS Score:
Base 8.6
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:X/RL:X/RC:X

CVE-2018-0277
 
Summary

  * A vulnerability in the Extensible Authentication Protocol-Transport Layer
    Security (EAP-TLS) certificate validation during EAP authentication for the
    Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote
    attacker to cause the ISE application server to restart unexpectedly,
    causing a denial of service (DoS) condition on an affected system.

    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.

Affected Products

  * Vulnerable Products

    The vulnerability affects the following Cisco ISE products:
      + Cisco ISE
      + Cisco ISE Express
      + 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

    Products Confirmed Not Vulnerable

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

    Cisco has confirmed that this vulnerability does not affect Cisco ISE
    Passive Identity Connector.

Workarounds

  * There are no workarounds that address this vulnerability.

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.
