I'm sure that I'm adding the exact numer of "../" because I was able to
retrive phpinfo.php and there I have the DOCUMENT_ROOT server variable...
It's under user Apache...but anyway...it is accessing the files for reading,
and all users have priviledges to access the passwd file for reading...
thanks,
Andy

Have you tried http://www.example.com/static.php?page=/etc/passwd
?????
Also, the issue you may be hitting is that the website root may be in a
deeper directory that you think, therefore you may need to do more
../../../../
It's worth giving a thought to the fact that Apache/PHP may/should be
running as an underprivilaged user and therefore shouldn't have the ability
to traverse that far.

Hi,
Working on a Web app testing...I have found that the uses the
so-vulnerable method of including files requested by php parameters:
www.example.com/static.php?page=hello.htm
(htm files are in /templates dir)
A the page in the parameter is requested statically, I did a
www.example.com/static.php?page=../static.php and I got that page source
code.
Therefore, I tried doing a
www.example.com/static.php?page=../../../../../../etc/passwd
but I get an error saying that file doesn't exist.
I user the same source code in my server, and I could retrieve the
file...what can be happening? I don't think it is under a chroot jail...
I'm working with Apache 2.0.48 and PHP 4.3.4
and the real server has Apache 2.0.52 an PHP 4.3.9....
Thanks in advance,
Andy
