CVE-2018-0423

TITLE

plural Cisco RV Product Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-010561

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 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 Cisco RV110W, RV130W, and RV215W are Cisco router products. A buffer overflow vulnerability exists in the management interfaces of many Cisco routers. Cisco RV110W, RV130W, and RV215W Routers are prone to a buffer-overflow vulnerability because they fail to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Failed exploit attempts will result in denial-of-service conditions. This issue being tracked by Cisco Bug ID CSCvj23206, CSCvj42727, and CSCvj42729. Cisco RV110W Wireless-N VPN Firewall is a firewall product
