Summary
Multiple vulnerabilities in Cisco Data Center Network Manager (DCNM)
Software could allow a remote attacker to inject arbitrary values into
DCNM configuration parameters, redirect a user to a malicious website,
inject malicious content into a DCNM client interface, or conduct a
cross-site scripting (XSS) attack against a user of the affected
software.
For more information about these vulnerabilities, see the Details
section of this security advisory.
There are no workarounds that address these vulnerabilities.

Affected Products
Vulnerable Products
These vulnerabilities affect all releases of Cisco Data Center Network
Manager (DCNM) Software prior to the first fixed release. For
information about affected software releases, consult the Cisco bug
IDs at the top of this advisory.
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
Five vulnerabilities in Cisco Data Center Network Manager (DCNM)
Software could allow a remote attacker to inject arbitrary values into
DCNM configuration parameters, redirect a user to a malicious website,
inject malicious content into a DCNM client interface, or conduct a
cross-site scripting (XSS) attack against a user of the affected
software.
The vulnerabilities are not dependent on one another; exploitation of
one of the vulnerabilities is not required to exploit another
vulnerability. In addition, a software release that is affected by one
of the vulnerabilities may not be affected by the other
vulnerabilities.
Details about the vulnerabilities are as follows.
Cisco Data Center Network Manager Bypass Client-Side Validation
Parameters Vulnerability
A vulnerability in the web-based management interface of Cisco DCNM
Software could allow an authenticated, remote attacker to inject
arbitrary values into DCNM configuration parameters for an affected
system, which could allow the attacker to execute arbitrary code on
the affected system.
The vulnerability is due to insufficient server-side validation of
user-supplied data in HTTP payloads that are sent to the affected
software. An attacker could exploit this vulnerability by bypassing
server-side protections and injecting arbitrary values into certain
configuration parameters for the affected software. A successful
exploit could allow the attacker to inject arbitrary values into DCNM
configuration parameters and execute arbitrary code on the affected
system.
The CVE ID for this vulnerability is: CVE-2017-12343
The Security Impact Rating (SIR) for this vulnerability is: Medium
Cisco Data Center Network Manager HTTP Header Injection Vulnerability
A vulnerability in the web interface of Cisco DCNM Software could
allow an unauthenticated, remote attacker to redirect a user of the
affected interface to a malicious, attacker-controlled website.
The vulnerability is due to insufficient input validation of values in
HTTP header parameters that are sent to the web interface of the
affected software. An attacker could exploit this vulnerability by
persuading a user to click a malicious link and injecting malicious
HTTP headers into HTTP messages that are sent to or from the affected
software. A successful exploit could allow the attacker to redirect a
user of the affected software to a malicious, attacker-controlled
website.
The CVE ID for this vulnerability is: CVE-2017-12344
The SIR for this vulnerability is: Medium
Cisco Data Center Network Manager Content Spoofing Vulnerability
A vulnerability in the web interface of Cisco DCNM Software could
allow an unauthenticated, remote attacker to inject malicious content
into the content that is displayed by the affected interface.
The vulnerability is due to insufficient input validation of user-
supplied values in HTTP parameters that are sent to the web interface
of the affected software. An attacker could exploit this vulnerability
by injecting malicious HTTP parameter values into HTTP messages that
are sent to the affected software. A successful exploit could allow
the attacker to inject malicious content into the content that is
displayed by the web interface of the affected software, which could
allow the attacker to persuade a user to follow malicious instructions
or click a malicious link.
The CVE ID for this vulnerability is: CVE-2017-12345
The SIR for this vulnerability is: Medium
Cisco Data Center Network Manager Stored Cross-Site Scripting Vulnerability
A vulnerability in the web-based management interface of Cisco DCNM
Software could allow an unauthenticated, remote attacker to conduct a
stored XSS attack against a user of the affected interface, which
could allow the attacker to execute arbitrary script code or access
sensitive browser-based information.
The vulnerability is due to insufficient validation of user-supplied
input by the web-based management interface of the affected software.
An attacker could exploit this vulnerability by persuading a user of
the affected interface to click a malicious link. A successful exploit
could allow the attacker to execute arbitrary script code in the
context of the interface or allow the attacker to access sensitive
browser-based information on the users system.
The CVE ID for this vulnerability is: CVE-2017-12346
The SIR for this vulnerability is: Medium
Cisco Data Center Network Manager Reflected Cross-Site Scripting Vulnerability
A vulnerability in the web-based management interface of Cisco DCNM
Software could allow an unauthenticated, remote attacker to conduct a
reflected XSS attack against a user of the affected interface, which
could allow the attacker to execute arbitrary script code or access
sensitive browser-based information.
The vulnerability is due to insufficient validation of user-supplied
input by the web-based management interface of the affected software.
An attacker could exploit this vulnerability by persuading a user of
the affected interface to click a malicious link. A successful exploit
could allow the attacker to execute arbitrary script code in the
context of the interface or allow the attacker to access sensitive
browser-based information on the users system.
The CVE ID for this vulnerability is: CVE-2017-12347
The SIR for this vulnerability is: Medium
Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
For information about fixed software releases, consult the Cisco bug
IDs at the top of this advisory.
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.
Exploitation and Public Announcements
The Cisco Product Security Incident Response Team (PSIRT) is not aware
of any public announcements or malicious use of the vulnerabilities
that are described in this advisory.
