On August 31, 2017 a vulnerability was made public that affected an estimated 140,000 AT&T U-verse installed routers. Five flaws were found in common consumer Arris routers used by AT&T customers and other internet providers around the world. The flaws were detailed in a blog post by Joseph Hutchins, who described some of the them as being as a result of "pure carelessness."
The report said Arris NVG589 and NVG599 modems with the latest 9.2.2 firmware are affected. With the lingering threat to thousands, I have decided to create this website to help people test their routers for the remote SSH vulnerability.
Your router at address 220.127.116.11 is currently not vulnerble to the AT&T/Arris Remote SSH Vulnerability
