Hack the Seattle VM (CTF Challenge)

This is another article for Boot2Root series in CTF challenges. This lab is prepared by HollyGracefull. This is just a preview of the original lab which stimulates the Ecommerce web application which contains common security errors. Current vulnerabilities are listed below :
  • SQL Injection (Error-based)
  • SQL Injection (Blind)
  • Reflected Cross-Site Scripting
  • Stored Cross-Site Scripting
  • Insecure Direct-Object Reference
  • Username Enumeration
  • Path Traversal
  • Exposed phpinfo()
  • Exposed Administrative Interface
  • Weak Admin Credentials
WalkThrough
Firstly, let’s locate our target.
Our target is 192.168.1.8. Let’s scan it with nmap.
nmap –p- -A 192.168.1.8

The only port we found open was 80. Next we fire up the nikto.
nikto –h 192.168.1.8

Through nikto we discovered two directories : /admin/ and /images/. OK! We made its mental note and decided to move forward with opening our target in browser.

Opening it on the browser we found that it was ecommerce site as hinted by the author. We checked every tab but found nothing except in the blog tab.

In the blog tab, when you will hover your mouse arrow over the admin in the phrase ‘Hey Admin!’. It will change from arrow to a hand that indicates that means it will open as it a click on.

When you click on it, it will show a username of admin. Ok! I made a note of it. Let’s now check clothing tab.

There is nothing useful in this tab. As the author hinted that website is vulnerable towards SQL attacks so let’s try one. This time let’s try a different SQL attack using BurpSuite. Capture the cookies of the webpage through BurpSuite.

Copy the cooky string and paste it in a simple text file.

Then start the SQL attack by typing the following command in the terminal of Kali.
sqlmap –r /root/Desktop/sea.txt –dbs
Here,
/root/Desktop/sea.txt is the path of the text file in which we had saved t he cookies.

This command will give us the name of following database.

Out of these databases we will dump the tables of seattle with the following command :
sqlmap –r /root/Desktop/sea.txt –D seattle –tables

And with that we will have all the name of the tables as you can see in the following image.

Next we will dump the columns of the tables with the following command :
sqlmap –r /root/Desktop/sea.txt –D seattle –T tblMembers –columns

The execution of the above command will show the table names as following :

Now in the table names there is a table password. Now we already have the username of the admin and we just want the password. So now we will dump the contents of password table.
sqlmap –r /root/Desktop/sea.txt –D seattle –T tblmembers –C password –dump

And voila! We have the password i.e. Assasin1

Now in the browser, go to my account tab and there you will find a login portal. Give the username and password of the admin and click on Login.

And you will be logged in as the admin.

This CTF does contain any flag. All that required was to have admin access and yooohoooo!! We have that.

Hack the Pentester Lab: from SQL injection to Shell VM

Today we are going to perform penetration testing in another lab, download it from here . Now install the iso image in VM ware and start it. The task given in this lab is to gain access of administration console and upload PHP webshell. Start your Kali Linux then open the terminal and type netdiscover command for scanning network. Here 192.168.0.105 is my target IP which is shown in the screenshot. Then explore this IP in browser When you will open target IP in browser you will get a web page having heading My Awesome Photoblog . On the top of left side it contains some tags: home; test;  ruxcon; 2010; all pictures; admin. Now Click on test . The above URL : http://192.168.1.105/cat.php?id=1 will run query for ID 1 now let try to find out whether the above URL is vulnerable to sql injection or not by adding ‘ at last of URL: http://192.168.1.105/cat.php?id=1 ’ . And I have got a message of sql error. It confirms that this web page is suffering from sql vulnerability. Now ...

Metasploitable 2 vulnerability assessment

A vulnerability assessment is a crucial part in every penetration test and is the process of identifying and assessing vulnerabilities on a target system. In this part of the tutorial we will be assessing the vulnerabilities available on the network side of the Metasploitable 2 virtual machine. We will be assessing the web applications on the Metasploitable 2 machine in a later tutorial. In the previous Metasploit enumeration and fingerprinting tutorial we’ve learned that the Metasploitable 2 machine contains a lot of vulnerabilities. We have collected valuable information about the target system which we will be using to find known vulnerabilities both on- and offline. Exploitation of these vulnerabilities will be demonstrated in the next exploitation tutorial. In this tutorial we will be looking at a few different ways to perform vulnerability analysis. We will be manually searching for exploits, use scanning tools like Nmap with scripts and we will be...

10 Security Vulnerabilities That Broke the World Wide Web in 2016

Information security is a subject in cyber-world which we can’t think away anymore. Data breaches can cost millions when sensitive information is leaked on the Internet. Zero-day exploits pop up for sale every day in deep web forums in return for Bitcoins. However, few exploits are disclosed in public domain once the vulnerability is patched by the vendor. This past year, we had over 6400 common vulnerabilities and exposures which were issued a CVE ID. There were few major bug fixes by the vendors serving backbone of the Internet. Here is the list of top 10 security vulnerabilities which came to light this year. 1. Dirty Cow (CVE-2016-5195) Discovered by Phil Oester,  Dirty Cow , is a kernel vulnerability that allows any unprivileged existing user to escalate its privilege to root. Root is the highest privilege on any UNIX or LINUX system, which has access to all the files. This vulnerability is known as privilege escalation. COW (Change on Write) is a technique used by Linux to re...
