Ask Slashdot: What To Do When Finding a Security Breach On Shared Hosting?

An anonymous reader writes "A few months ago I stumbled across an interesting security hole with my webhost. I was able to access any file on the server, including those of other users. When I called the company, they immediately contacted the server team and said they would fix the problem that day. Since all you need when calling them is your username, and I was able to list out all 500 usernames on the server, this was rather a large security breach. To their credit, they did patch the server. It wasn't a perfect fix, but close enough that moving to a new web host was moved down on my list of priorities. Jump a head to this week: they experienced server issues, and I asked to be moved to a different server. Once it was done, the first thing I did was run my test script, and I was able to list out everyone's files again. The hosting company only applied the patch to old server. I'm now moving off this web host all together. However, I do fear for the thousands of customers that have no clue about this security issue. With about 10 minutes of coding, someone could search for the SQL connection string and grab the username/password required to access their hosting account. What's the best way to handle this type of situation?"
