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
CVSSÂ 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

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.
