Summary
A vulnerability in the web-based management interface of Cisco IOS and
Cisco IOx Software could allow an unauthenticated, remote attacker to view
confidential information that is displayed without authenticating to the
device.
The vulnerability is due to lack of proper input validation of the HTTP URL
being requested. An attacker could exploit this vulnerability by sending a
crafted HTTP request to the targeted device. An exploit could allow the
attacker to view confidential information that should only be visible to
authenticated users to the device. The attacker could use this information
to conduct additional reconnaissance attacks.
