Thanks blue_cowdawg for your lengthy answer. There is so much to learn about Unix, servers, permissions, etc.

I've been using CGI::Application::Plugin::Config::Simple to read in my parameters. But tirwhan has me nervous about storing those logins at all.

Data validation ...

Thanks, I'm validating and untainting everything!

File uploads Treat with care.

I've been validating type, size, and then using CGI upload for this. Any other caveats?

Injection attacks...

Using placeholders for everything (I've been a monk long enough to never go without these)

Remote executions Web applications that allow random users to execute things

Do you have an example of this? I don't *think* I'm doing this.
