CVE-2018-0426

CRITICAL 9.8EPSS 6.37%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (6.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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 validation of directory traversal character sequences within the web-based management interface. An attacker could exploit this vulnerability by sending malicious requests to the targeted device. A successful exploit could allow the attacker to gain access to arbitrary files on the affected device, resulting in the disclosure of sensitive information.
