Netgear warns users to patch recently fixed WiFi router bug
Netgear has fixed a high-severity vulnerability affecting multiple WiFi router models and advised customers to update their devices to the latest available firmware as soon as possible.

How to update your router’s firmware
To download and install the latest firmware for your Netgear router, you have to go through the following steps:
- Visit NETGEAR Support.
- Start typing your model number in the search box, then select your model from the drop-down menu as soon as it appears.
- If you do not see a drop-down menu, ensure you entered your model number correctly or select a product category to browse for your product model.
- Click Downloads.
- Under Current Versions, select the first download whose title begins with Firmware Version.
- Click Release Notes.
- Follow the instructions in the firmware release notes to download and install the new firmware.
“The pre-authentication buffer overflow vulnerability remains if you do not complete all recommended steps,” Netgear also warned.
“NETGEAR is not responsible for any consequences that could have been avoided by following the recommendations in this notification.”
A Netgear spokesperson was not immediately available for comment when contacted by BleepingComputer earlier today for more information.
On Wednesday, Netgear urged customers to patch a second vulnerability that can be exploited to trigger a denial of service state in attacks targeting Wireless AC Nighthawk and Wireless AX Nighthawk (WiFi 6) routers.
Earlier this year, Netgear also fixed a bad Orbi firmware update that prevented customers from accessing their devices’ admin consoles.
