Netgear released firmware for its R6900 Nighthawk AC1900 Router which clears a vulnerability.
The new firmware is the Netgear R6900 Router Firmware 22.214.171.124.
In December, Netgear said 12 of its router models were vulnerable to device hijacking due to a remotely exploitable vulnerability.
The vulnerability allowed the execution of Linux commands if they end up appended to the URL of a page the victim visits. The appended commands execute with root privileges, and through them the attackers can make the device do pretty much anything they want to.
Router models confirmed to suffer from the issue are: R6250, R6400, R6700, R7000, R7100LG, R7300, R7900, R8000, R6900, D6220, D6400, and D7000.
Netgear just issued a firmware release for the R6900.
To apply the fix save and unzip the downloadable archive, establish a wired connection between your R6900 unit and the computer you saved the firmware on, and navigate to the router’s administration page (username and password should end up requested).
While there, it would be a good idea to save all settings that you have changed from the default values, as you might need to re-enter them manually after the upgrade.
Afterward, go to Maintenance > Router Upgrade > Browse, select the newly unzipped .img file, hit “Upload,” and the device will install.
During this process, avoid removing Ethernet/power cables from the devices, closing the web browser, powering down the router/computer, or interrupting the installation in any way, as it will cause device malfunctions.
