Insufficient input validation vulnerability in NETGEAR R7300

Insufficient input validation vulnerability in the LAN Setup feature of NETGEAR R7300 router allows authenticated administrators connected to the local network to perform unauthorized actions on the router.This issue was identified through testing in a controlled research environment using a simulated version of the router's software and has not been confirmed on physical production devices.
