Vulnerabilities could leave thousands of Netgear routers exposed

Trustwave has released findings on new vulnerabilities discovered in 31 models of Netgear routers, adding up to a minimum of 10,000 vulnerable devices, but could be as much as possibly over a million.

These new vulnerabilities allow an attacker to discover, or completely bypass, any password on a Netgear router, giving them complete control of the router, including the ability to change configuration, turn infected routers into botnets or even upload entirely new firmware. This comes on the heels of the December Netgear vulnerabilities, which were “Command Injection” based, showing the increasing severity of the issue in use of these routers.

Commenting on this, Mike Ahmadi, Global Director – Critical Systems Security at Synopsys, said “We have tested many routers and firewalls over the last decade, and have found vulnerabilities numbering in the thousands, using both fuzz testing and software composition analyses. Vendors typically build such devices for the stated functionality, which is to route traffic and block unwanted traffic, when used as intended.

“What many vendors fail to do, however, is adequately assess the inherent security of the devices they sell, thereby flooding the market with vulnerable devices. Some vendors have taken it upon themselves to address the inherent vulnerabilities, but the end user is often left guessing which devices are adequately tested, since there is currently no regulatory requirement to test to a given level of rigor, and any attempt to force such regulations are met with extreme resistance.

“The only way a consumer can determine the level of risk associated with a device is to run their own tests and determine what vulnerabilities are present, and use this information in procurement to force a vendor to fix the issues, or move on to another vendor that is doing a better job addressing such issues, or require a third party security audit, such as the UL CAP program.”
