CVE-2024-20470Network attack vector

Root code execution via unvalidated HTTP input

Published Oct 2, 2024 · Updated Oct 2, 2024

Command injection in Cisco Small Business RV Series Router Firmware allows remote authenticated users to execute code as root. The web-based management interface fails to validate user-supplied values in crafted HTTP input before passing them into a root-privileged execution path. Valid administrator credentials and access to the management interface are required; WAN reachability exists only when remote management is enabled.
