Good morning friends. Not all vulnerabilities are unauthenticated, sometimes we require credentials to exploit a vulnerability like the WordPress ajax loadmore Php upload exploit we saw in one of  previous howtos. But how do we get these credentials. Metasploit has an auxiliary module for WordPress user enumeration. Let’s see how this exploit works.

Start Metasploit and load the wordpress user enumeration exploit as shown below. Type command “show options” to see the options we can specify. We can see a variety of options. All the options are self explanatory but let us see some of the options.

The “BLANK_PASSWORDS” option if set will check if any of the users are without any password. The “VERBOSE”option will display more clearly what the module is doing. The “USERNAME” and “PASSWORD” option will check for single username and password respectively. The “USER_AS_PASS” option will check whether the username itself is being used as password. The USER_FILE and PASS_FILE are used to specify file for usernames and passwords to enumerate respectively. The VALIDATE_USERS option will first validate if user exists on the target even before trying to crack his password.

The “USER_PASS” file option allows us to specify the same file for username and password as shown below. Here I have specified a wordlist consisting of most common passwords as the USER_PASS file. When we execute the module, we can see that it will first validate all the usernames.

wpuserenum3 wpuserenum4

What if we know the username? The first question is how will we know the username. Just go through one of our previous howto : WordPress vulnerability assessment  with WPSCAN. The tool gave use a hint that username is “root”. Now we will set the username as root, specify a common password dictionary as password file as shown below.

wpuserenum5

When I run the script, it confirms that the username is valid and tries all words in the dictionary as password one by one.

wpuserenum6

After some time we can see that we successfully cracked the password for user “root” as “123456”.

HOW TO STAY SAFE:

Never use not only common passwords but also common usernames for your websites. Still most of the people tend to use common usernames like admin, administrator etc. and common passwords.

 

 

WordPress is one of the most popular CMS available for websites. It can be used to create a beautiful website, blog, or app. As its developers say, “WordPress is both free and priceless at the same time”. Its latest release to time, 4.5 has been downloaded 40,446,377 times till editing of this howto. But being popular in field of hacking has its own disadvantages. The latest version suffers from oEmbed Denial of Service (DoS), Password Change via Stolen Cookie and Redirect Bypass vulnerabilities.

Similarly every version of WordPress has some vulnerability or other. But how do we find out which version of WordPress is the site running. Metasploit has an auxiliary module for WordPress version detection. Let’s see how it works.

Start Metasploit and load the module. Type command “show options” to see the options we required for this module.

wpversion1

Multiple IP addresses can be set as shown below. I am trying five targets.

wpversion2

After assigning IP addresses, type command “run” to execute the exploit. The first target is my own. As you can see, our two of our targets responded with their version. But what about others? Maybe a firewall is blocking our request or maybe our targeturi is wrong. Please try this scan with targeturi set to “/” and also “/wordpress” for better results.

wpversion3

By the way, version 4.1 suffers from a arbitrary file upload vulnerability.

Good Evening friends. This howto is a direct sequel to our previous howto  WordPress vulnerability assessment with WPscan, so I suggest you go through that howto first and look out for the easter eggs. This howto is based on one of the vulnerabilities we found in our previous howto. To those newbies, who don’t know what is revolution slider,  it is a popular plugin used by many wordpress websites. Well, I am sure you have heard about Panama papers leak. Yeah, I’m talking about the leak of 11.5m files from the database of the world’s fourth biggest offshore law firm, Mossack Fonseca. It has been identified that Mossack Fonseca was using a vulnerable version of WordPress revslider plugin which resulted in the hack. All versions of the plugin from 2.1.7 to 3.0.95 are vulnerable to the attack.

This exploit was made public last year but still there are many wordpress websites using the vulnerable plugin( as with the case of Mossack fonseca ). Now let us see how this exploit works in Metasploit. Start Metasploit and search for our exploit as shown below.

revslider1

Load the exploit as shown below.

revslider2

Set the required options as shown below.

revslider3

Set the required payload. Here for illustration I am setting the famous meterpreter payload.

revslider4

You can also check if your target is vulnerable by using “check” command as shown below.( But we already know our target is vulnerable).

revslider5

You can execute the exploit by typing “exploit”. If all went well, you will get the meterpreter shell on victim system.

Hope that was helpful.

Good Evening friends. Hope you’re fine. After focusing on Joomla for some time, with this howto I have decided to focus on another popular CMS, that is WordPress. This howto is a pre-prequel to one of my articles on how to hack wordpress right here. This howto will have two other sequels and watch out for some easter eggs in this howto. ( Mind my talk about sequels,prequels and easter eggs, but did I tell you I am a big Marvel fan). Ok, ok, ok. Now let’s begin. The tool we will use here is called WPscan. WPScan is a black box WordPress vulnerability scanner that can be used to scan remote WordPress installations to find security issues and also for enumeration. It is by default installed in Kali Linux Sana. Now open a terminal and update our tool by typing command as shown below.

wpscan1

To scan a wordpress website, you have to give the url as shown below. For this howto, I am using a local installation of wordpress as target.  Assign the target as shown below. The scan will start as shown below.

wpscan2

Here are the screenshots of result of this scan. . As you can see we have  13 vulnerabilities in the present installation and the vulnerabilities are given below.

wpscan3

wpscan4

wpscan5

One of the easiest ways to hack a wordpress site is to exploit the plugins installed in the target as most of the wordpress vulnerabilities nowadays exist in the plugins installed on it. So it is very important to enumerate the plugins installed on our wordpress target. We can enumerate the plugins using the “enumerate” option as shown below.

wpscan6

The scan result will be as shown below.( And there you have the first easter egg). So totally we found four plugins. The first one is Ajax Load More Plugin. As the red exclamation mark shows, it is vulnerable and we have seen how to exploit this vulnerability in the sequel I told you about. If you haven’t gone through it, it’s here.

wpscan7

The second plugin is the vulnerable version of Akismet.

wpscan8

wpscan9

The third vulnerable plugin is the WordPress Slider revolution plugin. We will see more about this in our next howto.

wpscan10a

 

 

Another important aspect to find vulnerabilities in the wordpress is its theme.  Now let’s enumerate the theme as shown below. The vulnerabilities present in the theme are given below.

wpscan12

wpscan13

After that let’s enumerate the users in our remote target as shown below.

wpscan14

We can see that the only username in our target. That’s WPscan for you. Hope it was helpful to you and wait for the sequels.
