Cisco Security Advisory
Cisco Elastic Services Controller Service Portal Authentication Bypass
Vulnerability
Critical
Advisory ID: cisco-sa-20180221-esc
First Published: 2018 February 21 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvg29809
CVE-2018-0121
CWE-287
CVSS Score: Base 9.8
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:X/RL:X/RC:X
Summary
o A vulnerability in the authentication functionality of the web-based
service portal of Cisco Elastic Services Controller Software could allow an
unauthenticated, remote attacker to bypass authentication and execute
arbitrary actions with administrator privileges on an affected system.
The vulnerability is due to improper security restrictions that are imposed
by the web-based service portal of the affected software. An attacker could
exploit this vulnerability by submitting an empty password value to an
affected portal when prompted to enter an administrative password for the
portal. A successful exploit could allow the attacker to bypass
authentication and gain administrator privileges for the web-based service
portal of the affected software.
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:

cisco-sa-20180221-esc
Affected Products
o Vulnerable Products
This vulnerability affects Cisco Elastic Services Controller Software
Release 3.0.0.
To determine which Cisco Elastic Services Controller (ESC) Software release
is running on a system, administrators can use the esc_version command in
the ESC CLI and then refer to the output in the version field. The
following example shows the output of the command for a system that is
running Cisco ESC Software Release 4.0.0:
[admin@esc-4-0-0-80-uut ~]$ esc_version
version : 4.0.0
release : 80
yang.model.version : 152
repo : ssh://esc-repo
branch : master
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by this
vulnerability.
Cisco has confirmed that this vulnerability does not affect Cisco Elastic
Services Controller Software releases prior to Release 3.0.0.
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
This vulnerability is fixed in Cisco Elastic Services Controller Software
Releases 3.1.0 and later. Customers should upgrade to the latest software
release by visiting the Software Center on Cisco.com and navigating to
Products > Cloud and Systems Management > Service Management and
Orchestration > Elastic Services Controller.

CVE-2018-0130
CWE-264
CVSS Score: Base 7.3
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:X/RL:X/RC:X
Summary
o A vulnerability in the use of JSON web tokens by the web-based service
portal of Cisco Elastic Services Controller Software could allow an
unauthenticated, remote attacker to gain administrative access to an
affected system.
The vulnerability is due to the presence of static default credentials for
the web-based service portal of the affected software. An attacker could
exploit this vulnerability by extracting the credentials from an image of
the affected software and using those credentials to generate a valid
administrative session token for the web-based service portal of any other
installation of the affected software. A successful exploit could allow the
attacker to gain administrative access to the web-based service portal of
an affected system.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
