A Diary of mine was published today on the SANS Internet Storm Center. In this one, we take a look at how many publicly accessible systems are still vulnerable to CVE-2019-19781, AKA Shitrix.

My recent post on the Internet Storm Center website about the surprisingly high number of systems still affected by critical vulnerabilities, which have been patched for a long time, received quite a positive feedback. I have consequently decided to take a look at the issue in a more comprehensive manner and since I didn’t know, which vulnerabilities Shodan was able to detect, I’ve used my TriOp tool to gather data for all of the approximately 190k CVEs ever published. After couple of days the script took to run, I have the results and they are quite interesting…

If you've read any of my posts about open ports on public IP addresses either here or on the SANS Internet Storm Center website, you probably know that I'm interested in how the internet changes over time and I try to gain at least some understanding of it by analyzing data gathered over time from Shodan. Since I'm probably not the only one who finds the changes in numbers of different open ports interesting, I've decided to start publishing quarterly charts for the number of IPs, which have some of the more interesting ports open/services accessible from the internet...
