CWE-200

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.

    There are no workarounds that address this vulnerability.
