Where my infosec homies at??
They were issuing a single SSL cert to all of their clients. This cert was encrypting CC data.
That SSL cert lived on an FTP server.
The password was something like Spring2019!
We stored clients images on an SFTP server. I was a web dev. I didn't have access to the SFTP server. I had to tell a team what dirs to put assets in so my clients websites could display images.
... Tell me youve seen worse, and I'll continue to up the ante.
Current company I'm at I was reporting a slow Virtual server. It looked like one of the monitoring scripts was stuck in the loop and slowing the machine to a crawl.
Call up cyber, they proceed to tell me it's drive issue. The google DRIVERS Download the first thing they see an ad for some virus. The machine ended up needing to be completely reimaged.
Some days mannThey were issuing a single SSL cert to all of their clients.
How does this even work? Doesn’t the domain admin send their own CSR? Even if your company was serving as that admin, a single cert only works for the domain to which it’s assigned, so how could it be reused for multiple clients?
I think it was a self signed SSL.
Not all SSLs are domain specific. There's wildcard domains (used for subdomains or related domains), and self signed domains, and probably more.
Think like... A liquor store in the middle of nowhere that transmits CC data via internet. They have a SSL. They don't necessarily even have a registered domain.
Self-signed certs are not viable for general use because they’ll generate a browser warning that “Joes Liquor Co is not a trusted Certificate Authority” that will scare off 99% of users. And wildcard certs still need at least one specific domain, e.g.
*.joesliquor.com. The only way I can imagine this working is if the vendor was handing out separate servers onclient.vendor.comand giving each of them the same SSL cert for*.vendor.com.We would do the implementations. It would include Tomcat, IIS, and an out of date version of Internet Explorer. Beyond that, I'm not sure how they were getting by the warnings. All I can tell you is we were issuing one SSL certificate to multiple clients, and that SSL cert lived on our FTP server which had a very weak password.
I'm not sure I've seen worse, but I still want to see what's worse than what you've posted
Oh I can keep going, baby. We just scratched the surface.
Ever heard of ProgressABL?
