One of my first jobs gave me a task to work on and integrate some stuff they outsourced for dirt cheap. Almost immediately I found what was either a backdoor, or the most glaring security vulnerability I've seen in a while. The application had a way, accessible by anyone who can access the URL (anyone with internet access) to disable a number of security features that were there to prevent certain types of attack.
