Unauthenticated adjacent-network code execution
Published Nov 11, 2025 · Updated Nov 11, 2025
Improper input validation in NETGEAR DGN2200v4 firmware 1.0.0.126 and earlier allows remote attackers to execute code from the local network. NETGEAR has not published the affected component, accepted input, or validation operation that enables code execution. Exploitation requires direct network access to the router; the published assessment reports no required authentication or user interaction.
