Authenticated command execution via input validation flaw
Published Jan 13, 2021 · Updated Nov 12, 2024
Improper input validation in Cisco Small Business RV Series Router Firmware allows remote authenticated attackers to execute code or restart devices. The web-based management interface processes crafted HTTP request parameters without adequate validation, enabling command execution as root or a device reload. Valid administrator credentials are required; Cisco reports no software update and no known public or malicious exploitation.
