Summary

A vulnerability in the web-based management interface of Cisco Identity Services Engine could allow an authenticated, remote attacker to inject arbitrary commands on the underlying operating system. This vulnerability is due to improper validation of user input within requests as part of the web-based management interface. An attacker could exploit this vulnerability by manipulating requests to the web-based management interface to contain operating system commands.
