| I'm having trouble understanding how some less popular cms/guestbooks/forums authors code without having a single SQL injection yet a large amount of the most popular apps are filled with them. Even after previous versions of their app contained similar exploits. I'm sure everyone here knows how simple it is to santize user input, but a paradox still exists. |

I am not 100% agree. It's easy to use single quotes/sanityze all user submitted input/etc, but only in case of the light-weight software. If you look at source code of the much more sophisthicated pieces of software, like phpbb/vbulletin/ibb, then you can see, that 100% bughunt is impossible. Just too complicated working logic and execution flow, too many possible coincidents. So there is the point, where anti-hacking filters are handy - anti-sql-injection,anti-xss, etc. Because they are the next protecting layer, when potential attacker get's the way through sql/xss holes. I can imagine one more protection layer - NIDS - Network Intrusion Detection System, like Snort, with sql injection/xss/know exploits/worm attacks/etc pattern database. |

itis quite easy but if its not a huge CMS , which as every developer or user could modify n include the module n has many feature
there still "HUMAN ERROR" behind this 
nothing perfect, btw not all programmer aware about security  |
