Full list of NETGEAR router vulnerabilities revealed - is your device on the list?

09 Feb 2018

Many NETGEAR routers were subject to vulnerabilities that allowed attackers to take control of the devices through a password recovery feature.

Trustwave Spiderlabs researcher Martin Rakhmanov discovered the vulnerabilities last year. After a period of responsible disclosure and patching, he has revealed the five vulnerabilities:

1: Password recovery and file access on some routers and modem routers (PSV-2017-0677)

This vulnerability allows an attacker to read any file on the device as well as accessing administrative credentials by manipulating a password recovery feature.

This vulnerability affects 17 different Netgear products.

  • R6100 running firmware versions 1.0.1.12 and earlier

3: Authentication bypass on some router and modem routers (PSV-2017-1208)

Allows any attacker to bypass the need to authenticate. This vulnerability affects 17 different Netgear products.

  • D6220, running firmware versions prior to 1.0.0.26
  • D6400, running firmware versions prior to 1.0.0.60
  • D8500, running firmware versions prior to 1.0.3.29
  • R6250, running firmware versions prior to 1.0.4.12

4: Chained attack for command injection on some routers and modem routers (PSV-2017-1209)

By combining these vulnerabilities together any user connected to the router can run OS commands as root on the device without providing any credentials.

This vulnerability affects 17 different Netgear products.

  • D6220, running firmware versions prior to 1.0.0.26
  • D6400, running firmware versions prior to 1.0.0.60
  • D8500, running firmware versions prior to 1.0.3.29
  • R6250, running firmware versions prior to 1.0.4.12
  • R6400, running firmware versions prior to 1.01.24
  • R6400v2, running firmware versions prior to 1.0.2.30
  • R6700, running firmware versions prior to 1.0.1.22
  • R6900, running firmware versions prior to 1.0.1.22

5: Command injection vulnerability on D7000, EX6200v2, and some routers (PSV-2017-2181)

Setting a specific "device_name" parameter allows any user to execute any command if they use WPS to join the network.

This vulnerability affects six different Netgear products.

  • R6100 running firmware versions prior to 1.0.1.14
  • R7500 running firmware versions prior to 1.0.0.110
