CVE-2020-3146: Cisco rv110w wireless-n vpn firewall firmware memory buffer overflow vulnerability

Cisco · Rv110w Wireless N Vpn Firewall Firmware

Multiple vulnerabilities in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, RV130 VPN Router, RV130W Wireless-N Multifunction VPN Router, and RV215W Wireless-N VPN Router could allow an authenticated, remote attacker to execute arbitrary code on an affected device. The vulnerabilities are due to improper validation of user-supplied data in the web-based management interface. An attacker could exploit these vulnerabilities by sending malicious HTTP requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system of the affected device as a high-privilege user.
