And it also begs the question, "Why do you want to put everything on the Public Internet?" Hard-coded key vulnerability in Logix PLCs has severity score of 10 out of 10
10 out 10 is a hard score to get. 9.8 out of 10, sure. Steve Gibson of Security Now said it is like the Olympics. It is hard to get that score of 10.
Hardware that is widely used to control equipment in factories and other industrial settings can be remotely commandeered by exploiting a newly disclosed vulnerability that has a severity score of 10 out of 10.
The vulnerability is found in programmable logic controllers from Rockwell Automation that are marketed under the Logix brand. These devices, which range from the size of a small toaster to a large bread box or even bigger, help control equipment and processes on assembly lines and in other manufacturing environments.
This is really bad. EVERY Rockwell Automation's Logix PLC has the same, now publicly known, hard-coded password. Why? Because executives don't want to spend money on security. And besides who is ever going to figure this out? You engineers always want to spend money on something.
Today programmable logic controllers are everywhere you have a process you want to control. The types of places you might find a PLC: manufacturing lines, pharmaceutical plants, power plants, water treatment plants. I wouldn't be surprised to discover they are in cars and accessible via the diagnostic port.
