CVE-2016-1406
CWE-264
Summary
A vulnerability in the application programming interface (API) web interface
of the Cisco Prime Infrastructure and Cisco Evolved Programmable Network
Manager could allow an authenticated, remote attacker to perform privilege
escalation on the affected device. The attacker can escalate privileges to the
root level in most cases.
The vulnerability is due to incorrect role-based access control (RBAC)
evaluation when a low-privileged user requests a web page or service that
should be restricted. An attacker could exploit this vulnerability by
performing reconnaissance attacks to the application web pages and services to
identify potential devices of interest. The attacker could then craft an HTTP
request with a crafted JavaScript Object Notation (JSON) payload to request
the targeted sensitive data. An exploit could allow the attacker to perform
privilege escalation on the applications to the root level and access
unauthorized data.
Cisco has released software updates that address this vulnerability.
Workarounds that address this vulnerability are not available.
