Server Misconfigurations

Debugging Enabled

Some servers have debugging mode, which allows attackers to view errors, execute code, debug code, etc.

An indication of enabled debugging mode is that you might see a header like XDEBUG. Every debug library is different, but to connect to XDEBUG, you should open an xdebug listener (chromium has one), and send a GET request to the server like /?XDEBUG_SESSION_START=somesessionnameitdoesntmatter. Note that the server will connect to you, not the other way around.

This allows you to change server-side code, and you can get RCE.
