CVE-2025-4122Network attack vector

Authenticated command injection via crafted host argument

Published Apr 30, 2025 · Updated Apr 30, 2025

Command injection in NETGEAR JWNR2000v2 1.0.0.11 allows remote authenticated users to execute commands via a crafted host argument. In sub_435E04, the host value reaches command processing without neutralization of command syntax, so injected input is interpreted as an operating-system command. Access requires credentials for the router management interface, and successful exploitation executes injected commands on the router.
