Description
|
|
|
|
The plugin was affected by an IDOR issue, allowing students to see other student answers and grades
|
|
|
|
Proof of Concept
|
|
|
|
- Add 2 users with Student role for the scenario .
|
|
- Create A course With a quiz ( I picked True or Flase question for my quiz)
|
|
- Set Enrol on Free ( for the ease of scenario )
|
|
- Enrol into the Course with Student B and submit your answer to the Course .
|
|
|
|
The plugin will give a token like :
|
|
https://soft-dream.myliftersite.com/quiz/%d8%ac%d9%85%d8%b9-quiz/?attempt_key=wYK
|
|
To Check your answer was true or false.
|
|
|
|
Now Login as a Student A and Enroll in the Course. You can just use
|
|
the URL https://soft-dream.myliftersite.com/quiz/%d8%ac%d9%85%d8%b9-quiz/?attempt_key=wYK
