Cisco Application Policy Infrastructure Controller Access Control Vulnerability

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.
