Detailsinfo

A vulnerability has been found in Cisco RV110W, RV130W and RV215W (Router Operating System) (affected version unknown) and classified as critical. Affected by this vulnerability is an unknown functionality of the component Web-based Management Interface. The manipulation as part of a Request leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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 cause a denial of service condition or to execute arbitrary code. The vulnerability is due to improper boundary restrictions on user-supplied input in the Guest user feature of the web-based management interface. An attacker could exploit this vulnerability by sending malicious requests to a targeted device, triggering a buffer overflow condition. A successful exploit could allow the attacker to cause the device to stop responding, resulting in a denial of service condition, or could allow the attacker to execute arbitrary code.

The bug was discovered 09/05/2018. The weakness was published 10/05/2018 by Qingtang Zheng as cisco-sa-20180905-rv-routers-o as confirmed advisory (Website).
