Security Vulnerabilities Strike 50 Models of Netgear Routers

Saturday, Mar 7th, 2020 (7:31 am) - Score 5,307

Once again a mass of almost 50 different models of broadband wireless router(s), WiFi range extenders and gateways from Netgear, including some of their more recent kit (mostly affecting those within the D6000, R6000, R7000, R8000, PR2000, R9000 and XR500 families), have been hit by a string of new security vulnerabilities.

The security risk from these flaws tends to range in severity and the company has already released firmware updates so that customers can patch them ASAP. The first one (PSV-2019-0076) relates to a critical ‘Unauthenticated Remote Code Execution‘ bug on their R7800 router (firmware versions prior to

On top of that the same R7800 model, as well as a mass of other Netgear routers in the D6000, R6000, R7000, R8000, R9000 and XR500 families, are also affected by a ‘Post-Authentication Command Injection‘ (PSV-2018-0352) flaw. The danger level for this one is rated as ‘high’, rather than ‘critical’, for its severity and should also be patched ASAP.

Sadly we’re not finished yet. A ‘Pre-Authentication Command Injection‘ (PSV-2019-0051) flaw was found to affect several models of Netgear router within the R6000 and R7000 families (rated ‘high’ for severity), while a less serious ‘Authentication Bypass‘ (PSV-2018-0570) vulnerability (rated as ‘medium’ for severity) was found to impact various other router and gateway models in the same families, plus a PR2000 and JR6150.

Long story short, if you have any one of the models listed below (credits to Toms Guide) then hop along to the Netgear website and get the latest March 2020 firmware releases. Otherwise you risk your kit and network being broken into by amateur hackers or automated spammers intent upon stealing data, hijacking your computers or all sorts of other malicious things.

      No reason to panic. As far as I can tell these vulnerabilities were mostly patched ages ago. E.g. only XR500s running firmware versions prior to are affected. That firmware is dated 9 July 2018.

      Agree with Chris – just checked my router (d6400) and already running the needed firmware that was release last year.

    I picked good timing to move the R9000 that was on WAN detail back to access point detail behind a router/firewall.

      If you’ve got a R9000 (or R7800) then I highly recommend using Voxel’s firmware for better performance (these vulnerabilities were fixed yonks ago in Voxel’s fw). Upon request he can also add features which are missing from stock fw.
