Overview of the assignment

The assignment is worth 30% of your total unit mark.

Your goal in this assignment is to do security/penetration testing of a mini web application to identify web application and SQL injection vulnerabilities in it, using the techniques covered in our Web and database security lectures. Then, the goal is to demonstrate how to exploit the vulnerabilities discovered to break the app’s security. Finally, you will reflect on the invited lecture from Week 12 and on applying your unit knowledge in a daily life situation.

In Task 1 of the assignment (weight: 10% of your unit mark), you will demonstrate your understanding of XSS security vulnerabilities by testing the web application such vulnerabilities and assessing whether any vulnerabilities you find can potentially be exploited by an attacker.

In Task 2 of the assignment (weight: 4% of your unit mark), you will demonstrate your understanding   of client-side penetration testing techniques to attempt to bypass the web application’s mechanism for enforcing access control to private documents to authorised users.

Task 3 of the assignment (weight 6% of your unit mark) requires you to demonstrate your skills in testing for SQL injection vulnerabilities in a part of the web application that makes queries to an SQL database, and exploit any vulnerabilities you discover to breach gain unauthorised access to the database.

Task 4 of the assignment (weight 10% of your unit mark) requires you to write your reflection of the invited lecture in Week 12 and personal experience in relation to Cyber Security

You can download the Asg3 VM file from the link in the Moodle Asg3 Submission Page:

-    for Windows or Mac devices with Intel CPUs (.ova file), or

-    for Mac M1/M2 devices with VMWare Fusion player (.zip file), or

-    for Mac M1/M2 devices with UTM player (.qcow2 file), see Ed #222 Once you run the VM, log in with the following credential:

VM login name: student VM password: student

Your task is to perform the following security tests on this web application. You should perform these tests using the Firefox or burpsuite built-in web browser installed in your VM, and the burpsuite tool installed in the given VM.

Task 1 (10% of unit marks): Committee Member Security Test

Visit the homepage for the web application at the URL (http://alicefansclub.org/index.php) using your web browser. If all is well, the browser should display a page that looks as in Fig. 1.

Fig.1 Login Pag

This web app allows committee members of Alice Fans Club to access their personal documents.

In this part, your aim is to do security testing of the committee member part of the web application, from the point of view of an attacker trying to reveal the secret committee information. To help you with this, you are given the login credentials of one of the registered committee members (however, note that an outsider attacker may or may not know credentials other than provided):

Username: Alice Password: alice  City: Sydney

After clicking the “submit” button with the above credential, the browser should display a welcome page, as shown in Fig. 2.

Fig. 2. Welcome page

Then, after entering the event details e.g May 2024 and Sydney into the boxes and then clicking the “submit” button, you should see the show poster as shown in Fig. 3.

Fig. 3. Secret report of observation. Complete the following tasks:

● Task 1A (3 mark) Based on the application behavior. for login and welcome pages above:

o Based on the behaviour of the web application pages above with an honest user, list potential points on the home  and greeting pages where a reflected XSS input injection vulnerability may potentially exist. (No actual XSS attack is required in this task).

o Explain why the points you listed are potential XSS vulnerability points.

● Task  1B (7  mark) Experiment with the home page login and welcome and member report pages in Figs. 1-3, and examine the behavior. of these pages to different inputs. In particular:

o For each of the potential XSS vulnerability points listed in Task A.1, perform tests to see if XSS vulnerabilities actually exist at these points.

o   Assume you set up a web application server, craft a malicious script. that could allow the attacker to receive the target user’s session cookie by launching an XSS attack on one of the chosen vulnerability points.

o In the report,

.    Describe and explain your testing approach

.    Draw a table of test  results and your interpretation/conclusions on why or why not such XSS vulnerability exists (note: you only need to test if script injection is possible, no social engineering considerations are required).

.    Screenshot  of script.  and the feasibility of receiving cookies at the attacker’s application server. (note: you only need to show the script and evidence for its execution to steal the cookie,  no social engineering attack feasibility/demo is required)

.    Explain how to mitigate the vulnerabilities.

Task 2 (4% of unit marks): Personal Information Security Test

In this part, your aim is to do security testing of the fans’ personal information part of the web app. For this, you are given one of fans’ name and password, namely:

Member Name: Grace Member ID Number: 3

Member password: Ro4mvSemq45xfepvaEr24

Use Grace’s member ID number and Member password to log in to the Personal Private Information login page shown in Fig. 4.

Fig. 4. Personal Private Information login page. Complete the following tasks:

Grace has two private documents stored in his account with document IDs 1 and 2. Your goal in this task is to test the application against attacks by Grace (Member ID: 3) who is curious to learn about another member Camy’s (Member ID: 4) private information.

o Can Grace gain unauthorised access to Camy’s personal private data?

.    If you think it is possible, explain the vulnerability you found and how Grace can exploit it, and show any private data of Camy you managed to expose by the attack.

.    If you think it is not possible, explain why.

.    In  any case, explain  the tests you did, the results, and your interpretation of them.

Hints: experiment with the personal private information part of the web app to see how it behaves with different inputs from Grace. Use the burpsuite tool (see week 10 applied session) to help with your experiments and try out potential attacks.

Task 3 (6% of unit marks): Attack on the database

In this part, your aim is to test for potential database SQL injection vulnerabilities in the committee’s personal profile page. To do so, click the “here” link at the bottom of the “Welcome” page (see Fig. 5) after logging in as the user Alice as explained in Task A.

Fig. 5. Member welcome page with link to committee personal profile at bottom.

Alice’s personal profile search page should appear as in Fig.6.

Fig. 6. Member personal profile search page.

When you type in a username in the textbox under “ Please enter a username:” in the search page, the personal details of the member user (title, salary and phone no.) will be shown in the website.

For example, if you submit the form with username = “Alice”, the information will be as shown in Fig. 7.

Fig. 7. Search results for username “Alice ”.

Complete the following tasks:

Task 3A (4 marks)

In this task, you should test for SQL injection vulnerabilities via user input of the query to achieve the following tasks. You should include your injection inputs and the screen captures of results in your presentation.

3A.(i) Test to:

● Find out whether the username input box in the Fig. 7 page has an SQL injection vulnerability. What kind of SQL statement do you think is being used by the web application (Insert, Update, Select or other)?

● Try to craft a malicious input for the username input box to list information on all the users.

3A.(ii) Make use of the username textbox to find:

● all tables in the database

● among the possible tables, the name of the database table which likely contains user personal private information e.g. the user names, salary, and password

● list the corresponding names of fields (columns) in the database table you named above, and the values of three of the private information fields for all the users in the table

Task 3B (3 marks)

In the bottom half of the member personal profile search page (see Fig. 6), user Alice can update her phone no. by entering a new phone no. Your subtasks are:

3B.(i) What kind of SQL statement is being used in this box? Attempt to make use of the fields found in Task 3A to test for and exploit an SQL injection vulnerability in the phone update textbox to update some information other than phone no.

3B.(ii) Include your SQL injection malicious input and screen captures before and after the changes by using a member profile search page query, and explain your interpretation of the test results.

3B.(iii) How to prevent this type of attack?

Hints: Refer to the SQL statement quick reference to look for a likely SQL statement for subtask 3B.(i) and the statement syntax to help you craft your malicious input for subtask 3B.(ii).
