Denial-of-Service 2023 Practice Questions and Answers
with complete solution
During the penetration testing of the MyBank public website, Marin discovered a
credit/interest calculator running on server side, which calculates a credit return plan.
The application accepts the following parameters:
amount=100000&duration=10&scale=month
Assuming that parameter amount is the amount of credit, the user is calculating the
interest and credit return plan (in this case for 100,000 USD), parameter duration is the
timeframe the credit will be paid off, and scale defines how often the credit rate will be
paid (year, month, day, ...). How can Marin proceed with testing weather this web
application is vulnerable to DoS?
Change the parameter duration to a large number and change scale value to "day" and
resend the packet few times to observe the delay.
Change the parameter duration to a small number and leave scale value on "month"
and resend the packet few times to observe the delay.
Leave the parameter duration as is and change the scale value to "year" and resend the
packet few times to observe the delay.
Change the parameter duration to a small number and change scale value to "day" and
resend the packet few times to observe the delay.
Change the parameter duration to a large number and change scale value to "day" and
resend the packet few times to observe the delay.
