Summary

  o 
    A vulnerability in the Admin portal of Cisco Identity Services Engine
    (ISE) could allow an authenticated, remote attacker to obtain confidential
    information for privileged accounts.

    information. An attacker could exploit this vulnerability by logging into
    the web interface on a vulnerable system. An exploit could allow an
    attacker to obtain confidential information for privileged accounts. This
    information could then be used to impersonate or negatively impact the
    privileged account on the affected system.

    There are no workarounds that address this vulnerability.

Cisco Identity Services Engine Privilege Escalation Vulnerability

Priority:        High

Advisory ID:     cisco-sa-20190123-ise-privilege

First Published: 2019 January 23 16:00 GMT

Version 1.0:     Final

Workarounds:     No workarounds available

Cisco Bug IDs:   CSCvi44041

CVE-2018-15459   

CWE-284

CVSS Score:
6.5  AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N/E:X/RL:X/RC:X

Summary

  o A vulnerability in the administrative web interface of Cisco Identity
    Services Engine (ISE) could allow an authenticated, remote attacker to
    gain additional privileges on an affected device.

    The vulnerability is due to improper controls on certain pages in the web
    interface. An attacker could exploit this vulnerability by authenticating
    to the device with an administrator account and sending a crafted HTTP
    request. A successful exploit could allow the attacker to create
    additional Admin accounts with different user roles. An attacker could
    then use these accounts to perform actions within their scope. The
    attacker would need valid Admin credentials for the device. This
    vulnerability cannot be exploited to add a Super Admin account.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.

Affected Products

  o Vulnerable Products

    This vulnerability affects Cisco Identity Services Engine (ISE). For
    information about which Cisco ISE releases are vulnerable, see the Fixed
    Software section of this advisory.

    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: 3.0
        ADE-OS Build Version: 3.0.3.030

    Products Confirmed Not Vulnerable

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

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.

    Fixed Releases

    Customers with a device that is running an affected release are advised to
    upgrade to an appropriate release as indicated in the following table:

CVE-2018-15455   

CWE-79

CVSS Score:
6.1  AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X

Summary

  o A vulnerability in the logging component of Cisco Identity Services Engine
    could allow an unauthenticated, remote attacker to conduct cross-site
    scripting attacks.

    The vulnerability is due to the improper validation of requests stored in
    the system's logging database. An attacker could exploit this
    vulnerability by sending malicious requests to the targeted system. An
    exploit could allow the attacker to conduct cross-site scripting attacks
    when an administrator views the logs in the Admin Portal.

    There are no workarounds that address this vulnerability.
