Hello Brett!

LFI is interesting vulnerability (including in PHP web applications) and
there are known many methods of their exploitation. And Gynvael Coldwind
have added one more method.

Both Gynvael's and yours papers are interesting. With your work you showed
that phpinfo scripts are dangerous not just because of Information Leakage
and XSS (in PHP < 4.4.1, 4.4.3-4.4.6), but also as vector of exploitation of
LFI holes (if there are such ones at web site). Good work.

Best wishes & regards,

Whitepaper explaining how PHPInfo can be used to assist with the
exploitation of LFI vulnerabilities on PHP when combined with the
file upload handling feature that is enabled by default.
