CWE-200


Summary

A vulnerability in the web interface of Cisco RV132W ADSL2+ Wireless-N VPN
Routers and Cisco RV134W VDSL2 Wireless-AC VPN Routers could allow an
unauthenticated, remote attacker to view configuration parameters for an
affected device, which could lead to the disclosure of confidential information.

The vulnerability is due to the absence of user authentication requirements for
certain pages that are part of the web interface and contain confidential
information for an affected device. An attacker could exploit this vulnerability
by sending a crafted HTTP request to an affected device and examining the HTTP
response to the request. A successful exploit could allow the attacker to view
configuration parameters, including the administrator password, for the affected
device.

There are no workarounds that address this vulnerability.
