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.
