FIT3173 Software Security Assignment-2 (S1 2025)

Total Marks 100

Please see Moodle for the due date.

1 Overview

The primary learning objective of this assignment is to provide you with firsthand experience in exploiting

SQL Injection, Cross-site Scripting and Cross-site Request Forgery vulnerabilities. Additionally, it aims

to deepen your understanding of these vulnerabilities. This assessment does not require a specific virtual

machine (VM) and can be executed on any operating system. You can utilize the same setup as the Lab07

and Lab08.

2 Submission

For this assignment, you need to submit two files using a single submission link on Moodle:

? A PDF file with relevant screenshots, and

? a singlevideo filecontaining the recording of you carrying out all tasks.

Typeset your report into .pdf format (make sure it can be opened with Adobe Reader) and name it as the

format:[Your Name]-[Student ID]-FIT3173-Assignment.pdf.

All payloads, if required, should be embedded in your report. In addition, if a demonstration video is

required, you should record your screen demonstration with your voice explanation. You can use this free

tool to make the video:https://monash-panopto.aarnet.edu.au/ ; other tools, such as Zoom, are also fine.

Important notes and penalties:

? A part of the submitted video (at a corner) must clearly show your face at all times. Penalties may

apply when that’s not the case.

? Video demonstration should be a live exploitation of the vulnerabilities.

? Late submissions incur a 5-point deduction per day. For example, if you submit 2 days and 1 hour

late, that incurs 15-point deduction. Submissions more than 7 days late will receive a zero mark.

? If you require extension or special consideration, refer tohttps://www.monash.edu/students/

admin/assessments/extensions-special-consideration. No teaching team mem-

ber is allowed to give you extension or special consideration, so please do not reach out to a teaching

team member about this. Follow the guidelines in the aforementioned link.

? The maximum allowed duration for the recorded video is 15 mins in total. Therefore, only the first

15:00 mins of your submitted video will be marked. Any exceeding video components will be ignored.

? If your device does not have a camera (or for whatever reason you can’t use your device), you can

borrow a device from Monash Connect or Library. It’s your responsibility to plan ahead for this.

Monash Connect or Library not having available devices for loan at a particular point in time is not a

valid excuse.

? You can create multiple video parts at different times, and combine and submit a single video at the

end. Make sure that the final video is clear and understandable.

1

? You can do (online) research in advance, take notes and make use of them during your video recording.

You may also prepare exploit scripts in advance. But you cannot simply copy-paste commands to carry

out the tasks without any explanations. Explanations (of what the code does) while completing the

tasks are particularly important.

? Zero tolerance on plagiarism and academic integrity violations: If you are found cheating, penalties

will apply, e.g., a zero grade for the unit. The demonstration video is also used to detect/avoid plagia-

rism. University policies can be found athttps://www.monash.edu/students/academic/

policies/academic-integrity.

3 Web Application Vulnerabilities

Q1: Complete three labs fromPortSwigger Labs, one from SQL Injection, one from Cross-Site

Scripting, and one from Cross-Site Request Forgery section. Please select labs designated as PRAC-

TITIONER or EXPERT; APPRENTICE labs will not be accepted. You are permitted to utilize the

solutions and demonstrations available on the PortSwigger website for assistance. However, please

do not copy walkthroughs from the PortSwigger website. You will approach the labs as a penetration

tester, simulating a real-world scenario where you exploit each target as if you were doing it for the

first time. Your solution should include the logical steps that lead to the exploitation, which may not

be covered in the walkthroughs on the PortSwigger website.[60 Marks]

Record a video and write a report to answer the following questions for each lab. At the beginning

of each lab recording, please state your name, student ID, and the name of the lab you are solving;

no marks can be awarded without this information.

1. How did you identify the vulnerability? (5 Marks)

2. Which payload was chosen for exploitation and why? (5 Marks)

3. What an attacker could achieve using the vulnerability? (5 Marks)

4. How the vulnerability can be mitigated? (theoretically, no demonstration is required) (5 Marks)

The video submission must demonstrate solving the lab, addressing the questions outlined above. In

case time runs short during the video, you may use the report to address any unanswered questions,

making references to relevant sections of the video. However, it is important that the video includes,

at a minimum, a demonstration of the lab. The report does not need to be in detail, it should briefly

address the mentioned questions, i.e. it can contain one or two-line answer for each question, pay-

loads and important screenshots (if necessary). The marks mentioned above are for the videos and

report combined.The word limit for each sub-question is 200 words, i.e. maximum 800 words

are allowed for Q1 per lab.

Q2: Download theQ2.htmlfile from Moodle. Assume you are browsingmonash.edu, and

it is hypothetically vulnerable to various web attacks (although it is not).While navigating

monash.edu, assume you open another tab in the same browser, and visitattacker.com(as-

suming attacker convinced you to do that). You click theSubmitbutton on theattacker.com

webpage, which containsQ2.html, initiating attacks onmonash.edu. ExamineQ2.html(you

can open the file in the browser and intercept the request in BurpSuite if desired) and respond to the

following questions.No video is required for this question. The word limit for each sub-question

is 200 words, i.e. maximum 600 words are allowed for Q2. [20 Marks]

1. Which vulnerability/vulnerabilitiesattacker.comis trying to exploit onmonash.edu?

(please explain the scenario outlining how this exploitation could occur) (10 Marks)

2. If successful, what is the consequence of the attack(s)? (5 Marks)

3. What mitigation(s) would you suggest formonash.eduto counter attack(s) launched by

attacker.com? (5 Marks)

Note: The parameter values in the HTML file are URL encoded.

Q3: Assume you visitmonash.eduand it tries to talk tolms.monash.edu, the browser issues

an OPTIONS method tolms.monash.eduand gets a response, below is the HTTP request and

its response:
