CVE-2025-4121Network attack vector

Authenticated command execution via cmd_wireless host injection

Published Apr 30, 2025 · Updated Apr 30, 2025

Command injection in NETGEAR JWNR2000v2 1.0.0.11 allows remote authenticated users to execute commands through its web interface. The cmd_wireless function interprets crafted command syntax supplied through its host argument instead of treating the value solely as data. Authenticated access to the router's management interface is required; successful injection executes attacker-supplied command text on the router.
