Auth bypass in Cisco Rv132w

CVE-2018-0127

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. Cisco Bug IDs: CSCvg92739, CSCvh60172.
