CVE-2018-0425: Cisco Rv110w Firmware: Authentication bypass

CVE-2018-0425 is rated critical with a CVSS v3.0 base score of 9.8 and NVD lists 3 affected products, including Cisco Rv110w Firmware. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

A vulnerability in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router could allow an unauthenticated, remote attacker to gain access to sensitive information. The vulnerability is due to improper access control to files within the web-based management interface. An attacker could exploit this vulnerability by sending malicious requests to a targeted device. A successful exploit could allow the attacker to gain access to sensitive configuration information, including user authentication credentials.
