Cisco Application Policy Infrastructure Controller Access Control
2016 February 3 16:00 GMT
Base - 8.5
No workarounds available
Cisco Bug IDs:
A vulnerability in the role-based access control (RBAC) of the Cisco
Application Policy Infrastructure Controller (APIC) could allow an
authenticated remote user to make configuration changes outside of their
configured access privileges.
The vulnerability is due to eligibility logic in the RBAC processing code. An
authenticated user could exploit this vulnerability by sending specially
crafted representational state transfer (REST) requests to the APIC. An
exploit could allow the authenticated user to make configuration changes to
the APIC beyond the configured privilege for their role.
Cisco has released software updates that address this vulnerability.
This advisory is available at the following link:
The following products are known to be affected by this vulnerability when
running affected versions of software:
Cisco Application Policy Infrastructure Controllers when running software
versions prior to 1.0(3h) and 1.1(1j)
Cisco Nexus 9000 Series ACI Mode Switches when running software versions prior
to 11.0(3h) and 11.1(1j)
This vulnerability affects configurations that are using either
signature-based transactions or username/password configurations.
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by this
There are no workarounds that address this vulnerability.
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:
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
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):
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.
