Summary
o Multiple vulnerabilities in the REST and SOAP API endpoints of Cisco Data
Center Network Manager (DCNM) could allow an authenticated, remote attacker
to execute arbitrary SQL commands on an affected device. To exploit these
vulnerabilities, an attacker would need administrative privileges on the
DCNM application.
For more information about these vulnerabilities, see the Details section
of this advisory.
Note: The severity of these vulnerabilities is aggravated by the
vulnerabilities described in the Cisco Data Center Network Manager
Authentication Bypass Vulnerabilities advisory, published simultaneously
with this one.
Cisco has released software updates that address these vulnerabilities.
There are no workarounds that address these vulnerabilities.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/
cisco-sa-20200102-dcnm-sql-inject
Affected Products
o Vulnerable Products
These vulnerabilities affect Cisco DCNM software releases earlier than
Release 11.3(1) for Microsoft Windows, Linux, and virtual appliance
platforms.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by these vulnerabilities.
Details
o Two vulnerabilities in the REST and SOAP API endpoints of Cisco DCNM could
allow an authenticated, remote attacker to execute arbitrary SQL commands
on an affected device.
The vulnerabilities are not dependent on one another; exploitation of one
of the vulnerabilities is not required to exploit the other vulnerability.
In addition, a software release that is affected by one of the
vulnerabilities may not be affected by the other vulnerability.
Details about the vulnerabilities are as follows.
Vulnerability Details
Cisco Data Center Network Manager REST API SQL Injection Vulnerability
A vulnerability in the REST API of Cisco DCNM could allow an authenticated,
remote attacker with administrative privileges to execute arbitrary SQL
commands on an affected device.
The vulnerability is due to insufficient validation of user-supplied input
to the API. An attacker could exploit this vulnerability by sending a
crafted request to the API. A successful exploit could allow the attacker
to view information that they are not authorized to view, make changes to
the system that they are not authorized to make, or execute commands within
the underlying operating system that may affect the availability of the
device.
CVE ID: CVE-2019-15984
Cisco Data Center Network Manager SOAP API SQL Injection Vulnerability
A vulnerability in the SOAP API of Cisco DCNM could allow an authenticated,
remote attacker with administrative privileges to execute arbitrary SQL
commands on an affected device.
The vulnerability is due to insufficient validation of user-supplied input
to the API. An attacker could exploit this vulnerability by sending a
crafted request to the API. A successful exploit could allow the attacker
to view information that they are not authorized to view, make changes to
the system that they are not authorized to make, or execute commands within
the underlying operating system that may affect the availability of the
device.
CVE ID: CVE-2019-15985
Workarounds
o There are no workarounds that address these vulnerabilities.
Fixed Software
o Cisco has released free software updates that address the vulnerabilities
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
Cisco fixed these vulnerabilities in Cisco DCNM Software releases 11.3(1)
and later.
To download the software from the Software Center on Cisco.com, do the
following:
1. Click Browse All .
2. Choose Cloud and Systems Management > Data Center Infrastructure
Management > Data Center Network Manager .
3. Choose a release from the left pane of the Data Center Network Manager
page.
