The web-based management interface on Cisco RV110W devices with firmware before 184.108.40.206, RV130W devices with firmware before 220.127.116.11, and RV215W devices with firmware before 18.104.22.168 allows remote attackers to execute arbitrary code as root via a crafted HTTP request, aka Bug ID CSCux82428.
A vulnerability in the web 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 execute arbitrary code as root on a targeted system.
The vulnerability is due to insufficient sanitization of HTTP user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request with custom user data. An exploit could allow the attacker to execute arbitrary code with root-level privileges on the affected system, which could be leveraged to conduct further attacks.
Cisco has released firmware updates that address this vulnerability. Workarounds that address this vulnerability are not available.
