CVE-2016-1290
CWE-264
Summary
A vulnerability in the web application programming interface (API) of Cisco
Prime Infrastructure and Cisco Evolved Programmable Network Manager (EPNM)
could allow an authenticated, remote attacker to gain elevated privileges.
The vulnerability is due to improper role-based access control (RBAC) when an
unexpected HTTP URL request is received that does not match an expected
pattern filter. An attacker could exploit this vulnerability by sending a
crafted HTTP request with a modified URL to bypass RBAC settings. An exploit
could allow the attacker to gain elevated privileges for the application and
gain unauthorized access to data.
Cisco has released software updates that address this vulnerability.
Workarounds are not available.

Affected Products
Vulnerable Products
Cisco Prime Infrastructure
Cisco Prime Infrastructure software versions 1.2 and later are vulnerable. To
determine the version of software that is running on the device,
administrators can issue the show version command from the command-line
interface (CLI). The following output is from an affected device running Cisco
Prime Infrastructure software version 1.4.0.45:
NCS1-2-1-12/admin# show version
Cisco Application Deployment Engine OS Release: 2.0

Cisco Evolved Programmable Network Manager
Cisco EPNM software version 1.2 is vulnerable.
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by this
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.
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 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 the
applicable table in this section. To help ensure a complete upgrade solution,
consider that this advisory is part of a collection that includes the
following advisories:

CVE-2016-1291
CWE-20
Summary
A vulnerability in the web interface of Cisco Prime Infrastructure and Cisco
Evolved Programmable Network Manager (EPNM) could allow an unauthenticated,
remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to insufficient sanitization of HTTP user-supplied
input. An attacker could exploit this vulnerability by sending an HTTP POST
with crafted deserialized user data. An exploit could allow the attacker to
execute arbitrary code with root-level privileges on the affected system,
which could be used to conduct further attacks.
Cisco has released software updates that address this vulnerability.
Workarounds are not available.
