Yay, another PHP bashing paper. *cool* Sarcasm aside, this is all the more reason why one should validate/filter user input. The paper's details are new to me, however, as a web developer I can confidently say that my filename-management-related routines are completely safe against this attack. Why? Because special characters such as those mentioned in the paper (which by the way, aren't valid filename characters), are replaced be a legal and safe alternative (such as a dash or underscore).
We can blame PHP's magic. Then again you can blame C and C++'s pointer magic is the biggest security bug ever. Or you can blame the human factor behind the end, defective, product. Either-case, interesting study. My only complaint? Keep uninformed opinion to yourself next time though, it only dirties you arguments. Cheers, Chris.
