Re: FW: Serious Hole in Comment/Discussion CGI Script

Well I tried the nullbyte/%00 trick and it was a no go. And no the script
does
not parse out metacharacters

But wait a second... No it won't work, because the script doesn't seem to
do "toAscii" conversion. Tried sending a raw zero, ascii 0? If the
operating system the script is used on doesn't allow it in environment, it
should work. Only I suspect most C-based operating systems will choke on
null in environments, so quite likely the bug remains theoretical.

Happy hunting in the bugtracking :)
