From SQL injection to shell: PostgreSQL edition

be sure to read the prequel if you haven't done anything like that before: https://www.pentesterlab.com/from_sqli_to_shell.html

If I use sql parameters in my queries, am I still vulnerable to SQL injection? What about using a (sane) ORM?

Basically, is it only php apps that hand-build queries that are vulnerable to SQL injection?

Any app that hand-builds queries. PHP has nothing to do with this. Just happens to be the vehicle. The problem is simply insecure patterns.

What if I have no PHP?)
