CVE-2016-1388
CWE-20
Summary
A vulnerability in the web interface of Cisco Network Analysis Modules could
allow an unauthenticated, remote attacker to execute arbitrary commands on the
underlying operating system of the affected device with the privileges of the
web server.
The vulnerability is due to a failure to properly sanitize user input prior to
executing an external command derived from the input. An attacker could
exploit the vulnerability by submitting a crafted HTTP request to the affected
device. A successful exploit could allow the attacker to execute arbitrary
commands or code on the underlying operating system with the reduced
privileges of the web server.
This advisory is available at the following link:

vulnerability.
Workarounds
There are no workarounds that address this vulnerability.
Fixed Software
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:
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html

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 consult the Cisco
Security Advisories and Responses archive at http://www.cisco.com/go/psirt and
review subsequent advisories to determine exposure and a complete upgrade
solution.
In all cases, customers should ensure that the devices to upgrade 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 Technical Assistance Center (TAC):
http://www.cisco.com/en/US/support/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 should upgrade to an appropriate release as indicated in this
section. To help ensure a complete upgrade solution, consider that this
advisory is part of a collection that includes the following advisories:

CWE-20
A vulnerability in the web interface of Cisco Prime Network Analysis Module
(NAM) and Cisco Prime Virtual Network Analysis Module (vNAM) could allow an
authenticated, remote attacker to execute arbitrary commands or code on the
host operating system with the privileges of the web server.
The vulnerability is due to insufficient sanitization of user-supplied input
before the input is used in subsequent operations. An attacker could exploit
this vulnerability by submitting a crafted HTTP request to an affected system.
A successful exploit could allow the attacker to execute arbitrary commands or
code on the host operating system with the reduced privileges of the web
server.

CVE-2016-1370
Summary
A vulnerability in the IPv6 packet decode function of the Cisco Network
Analysis Module (NAM) could allow an unauthenticated, remote attacker to cause
a denial of service (DoS) condition.
The vulnerability is due to an improper calculation of the IPv6 payload length
of certain IPv6 packets. An attacker could exploit this vulnerability by
sending crafted IPv6 packets on the network where the NAM is collecting and
monitoring traffic. An exploit could allow the attacker to cause a DoS
condition and the NAM could cease to collect and monitor traffic for a short
time.
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:

Vulnerable Products
Cisco Prime NAM software versions prior to release 6.2(1-b).
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by this
vulnerability.
Indicators of Compromise
Exploitation of this vulnerability could cause gaps in traffic monitoring
along with a crash of the mond process. The crash of the mond process can be
indicated by the following error logs:
mond is not responding
