A recent exploit I became aware of results from php code that allowed global variables and URL injection to access the system. A friend's server became a spam bot for the attacker. Even though the mail server did not allow relaying, they were able to send it from the local host and got around that restriction.. Any path is a possible weakness, and one weakness leads to others. If the door is not there (package not installed) it cannot be opened.
