Administrator command execution via invalid NTP settings
Published Oct 13, 2026 · Updated Oct 13, 2026
Command injection in NETGEAR router NTP settings allows remote authenticated users to execute commands from the local network. CBR40, R7000, R7000P, and RAX40 insufficiently validate time-server setting input; NETGEAR has not disclosed the underlying function or command-construction operation. Exploitation requires router administrator credentials and local-network access, and the reported consequence is unauthorized router modification without confidentiality or availability impact.
