RBS750 vs PSV-2020-0432
That latest 2021/01/21 Security bulletin states the RBS750 is susceptable to the hack if firmware is equal to or lower than
- RBS40V running firmware versions prior to 2.6.2.4
- RBS750 running firmware versions prior to 3.2.17.12
- RBS850 running firmware versions prior to 3.2.17.12
- ...
Yet, the latest firmware found in the "Update" logs is
Check for new version from the Internet. [Check] Status: Model Name Device Name Current FW Status Router CBR750 CBR750 V3.2.16.18 No New Firmware Available Satellite RBS750 Orbi.. V3.2.16.22 No New Firmware Available
And what is worse, is that in grabbing this information I just found out my 'upgrade' to the CBR750 firmware showed failed days AFTER is succeeded (yes, I even posted a grab of the update page and posted it in another thread days ago). But then, wait for it, the router is having DNS issues, and even it's internal check for updates is failing... lmao.
So back to the fact the advisory that lists firmware that is later than what the updater finds - this seems to be routine for Netgear - as it just happened on my CBR40, too.
So the latest available to me is:
https://www.netgear.com/support/product/CBK752.aspx#download
- Current Versions
- CBR750 (Orbi Cable Router) Firmware Version 3.2.16.18
- RBS750 (Orbi Satellite) Firmware Version 3.2.16.6
It seems after some digging there are TWO RBS750 models. Not exactly a smart naming convention Netgear. One is for the RBR750/RBS750 pair, and a different model for the CBR750/RBS750 pair. Whoever is writing these security bulletins should probably be told this fact.

- RBS750 running firmware versions prior to 3.2.17.12. Not equal too.
The RBS750 model is used with the CBK750 and the RBR750 kits. There the same RBS models
Then why are there THREE 'latest firmware' releases? And which one is really the latest?
My RBS750 satellite has V3.2.16.22 installed and reports this is the latest available.
The Orbi CBK752 page shows a latest RBS750 (Orbi Satellite) Firmware Version 3.2.16.6 (older than installed?).
The Security notice says the RBS750 is vulnerable if the RBS750 is running firmware versions prior to 3.2.17.12.
So where do I get V3.2.17.12 ???
And - if I download the version you link for the standalone RBS750, the update fails because the file is for the wrong version of RBS750. I must use the CBK752 download page to get the correct version for my RBS750 from

I'm thinking Netgear has no web master to maintain order, and teams change pages willy-nilly... lol.
ps: if I log into the RBS750 via the CBR750 and try using the system firmware updater, it fails: if I direct connect to the RBS750 with a cable, it will accept the 3.2.17.12 version found above. So even their mesh updater is broken.
pps: Now, I wonder when they plan to update the CBR750 to fix the vulnerability. It has the same basics as the RBR750, only with a cable modem stuck on the WAN side of the router.
