NetUSB Security Defect Influences Countless Routers, See If Yours On The List

A company specializing in advising on details security has published a report into a vulnerability discovered within an element called NetUSB, an exclusive technology found within millions of house routers all over the world. NetUSB is established by a Taiwanese business called KCodes and is basically offered as a method of allowing PCs and Macs to connect to USB devices over a network. The bug within the innovation, if made use of, might essentially permit malicious people to jeopardize any device running the driver.


NetUSB is a specifically essential part of the innovation substance found within home routers due to its capability to provide “USB over IP.”Any USB device, such as a printer, external disk drive, or a flash drive, can be plugged directly into a router or access point including the KCode software application and is right away provided through the network using a Linux kernel driver. In its most basic type it essentially makes use of the client side of the software application readily available for Windows and OS X to mimic the experience of having a device plugged in locally using USB.

According to the review by SEC Consult, the concern within the software application depends on the motorist on the router-side of the formula, and is essentially a reasonably simple buffer overflow problem that is not just a classic throwback to the 1990s however is more worrying in that we actually don’t see these kinds of concerns these days. As part of the communication procedure between the client and the server, the client side sends out the name of the computer system to the software on the server side.

The concerning part is that if the name of the sent out device is longer than 64 bytes then it produces a buffer overflow, a concern that SEC Get in touch with says can be made use of by harmful people to crash the router utilizing a rejection of service attack, or perhaps worse, execute remote code.


The security company likewise discovered that the impacted NetUSB drivers are set up in a variety of extremely popular routers, including those made by D-Link, Netgear, TP-Linkand ZyXEL. Whether the issue exists in all of these routers is another matter as some nay not in fact have the impacted drivers running. Still, it makes the Web of Things look like a horrible idea, right?

The complete list of impacted routers is as follows:
