Older Windows PC's no longer see networked drives w/ R7000 when using firmware v1.0.11.216 or newer
I noticed that there were some serious security vulnerabilities with the R7000 router, in particular:
CVE-2022-48196
CVE-2022-37235
CVE-2022-37234,
for which a cyber attacker can use a technique termed "pre-authentication buffer overflow" to access your router, run code on your computer, and engage in identity theft. Is this a simple task and how prevalent has this been?
This vulnerability affects R7000 firmwares v1.0.11.134_10.2.119 and older. There have since been two firmware releases which addressed this buffer overflow vulnerability, namely
v1.0.11.216_10.2.122
v1.0.12.216_10.2.122.
If I apply either of these two firmware patches, I am no longer able to access shared drives on older networked Windows computers, nor access the router's network attached storage share folder (NAS). I primary use Ubuntu, which hasn't had an issue accessing the router's network attached storage, however my older computers, like Windows XP, which I sometimes need to use, can no longer see the router's NAS. I might briefly attach the ethernet cable on an XP machine to pull files from the NAS.
How do I get either, v1.0.11.216_10.2.122 or v1.0.12.216_10.2.122 to network share with older Windows computers? These older Windows computers, on the other hand, can still access the internet with updated browsers, e.g. Thorium, MyPal, etc, however they cannot view the NAS. Is there some setting I am missing in the router setup? Is this limitation in the newer firmware's by design? If I revert back to v1.0.11.134_10.2.119, there is no issue.
Thanks for your help!

I posted the same question in another forum and someone mentioned that Netgear probably disabled SMB v1 on the latest Netgear firmwares, however it might be possible to re-enable SMB v1 through the firmware's config files. Does anyone know how to do this?
Alternately, could Netgear please re-release the firmware with SMB v1 re-enabled, or at least make it a toggle switch to the end user in the UI? Thanks.
the R7000 is a 12 year old router. It was released in 2013. Its been on the end of life bulletin for a while. So you aren't going to see much development/changes with it.
Your best option? The r7000 was one of the devices that could run 3rd party firmware like ddwrt/tomato. they still get updates/development and in certain cases, work extremely well. Might be an option if you're wanting to continue to use an ancient router.
The latest firmware for the R7000 was released just a few months ago, so unless another critical vulnerability is discovered, I'd imagine the router has some time left on it.
I don't think a new router will resolve the issue with older computers not being able to access the NAS. I would imagine that all new Netgear routers now have SMB v1 disabled, thus buying new won't resolve my issue.
At some point, I may look into a 3rd party firmware, but there exists the risk of ruining the router entirely.
