Unfortunately, they don't ask the question of how this thing will be automagically updated each time a vulnerability is fixed, so the program never gets updated. Those programs get a lot of security updates (don't believe me? see http://www.securityfocus.com/bid and query your favorite php program). Look in your /var/log/httpd/error.log and you will probably see several hundred attempts to break into various php scripts. OT, a famous and recent example is the group in Canada who was busted for cracking web contact forms and sending out truly massive amounts of spam. Their technique required the mental acumen of a 5th grader in my estimate, but worked because of an abundance of really poorly written web contact scripts which never got updated. If the cracked script runs with sufficient authority to add a web page, the phishers job becomes trivial. The solution is for maintainers to make sure that they can notify their customers each time a security fix is made. This can be done in the script or by mandatory registration before a download. Yum repositories and the equivalent for other distros should be helpful in solving this problem.
This becomes even worse when you consider hosting sites. The last one I dealt with had everyone on virtual servers that had no capacity to update the packages installed. (Yum was not installed. No patches had been applied. You could actually break the system because they had plesk installed and packages would conflict. A real mess.)
People think that just because someone set it up for them, it is secure. Rarely is that the case.
People are trying to do complex things on the cheap. You are not seeing it done under Windows because doing anything useful is either not cheap or not easy.
Under Linux they can do what they want, but they are too cheap to hire someone who has clues and can do it securely.
