The challenges in this chapter are all about files or features that were simply forgotten and are completely unprotected against access.
Challenges covered in this chapter
|Let us redirect you to a donation site that went out of business.|
|Use a deprecated B2B interface that was not properly shut down.|
|Retrieve the language file that never made it into production.|
|Deprive the shop of earnings by downloading the blueprint for one of its products.|
Let us redirect you to one of our crypto currency addresses
One of the sites that the Juice Shop accepted donations from went out of business end of 2017.
- When removing references to those addresses from the code the developers have been a bit sloppy.
- More particular, they have been sloppy in a way that even the Angular Compiler was not able to clean up after them automatically.
- It is of course not sufficient to just visit any of the crypto currency links directly to solve the challenge.
Use a deprecated B2B interface that was not properly shut down
The Juice Shop represents a classic Business-to-Consumer (B2C) application, but it also has some enterprise customers for which it would be inconvenient to order large quantities of juice through the webshop UI. For those customers there is a dedicated B2B interface.
- The old B2B interface was replaced with a more modern version recently.
- When deprecating the old interface, not all of its parts were cleanly removed from the code base.
- Simply using the deprecated interface suffices to solve this challenge. No attack or exploit is necessary.
Retrieve the language file that never made it into production
A project is internationalized when all of the project’s materials and deliverables are consumable by an international audience. This can involve translation of materials into different languages, and the distribution of project deliverables into different countries.1
Following this requirement OWASP sets for all its projects, the Juice Shop's user interface is available in different languages. One extra language is actually available that you will not find in the selection menu.
- First you should find out how the languages are technically changed in the user interface.
- Guessing will most definitely not work in this challenge.
- You should rather choose between the following two ways to beat this
- Apply brute force (and don't give up to quickly) to find it.
- Investigate online what languages are actually available.
Deprive the shop of earnings by downloading the blueprint for one of its products
Why waste money for a product when you can just as well get your hands on its blueprint in order to make it yourself?
- The product you might want to give a closer look is the OWASP Juice Shop Logo (3D-printed)
- For your inconvenience the blueprint was not misplaced into the same place like so many others forgotten files covered in this chapter
If you are running the Juice Shop with a custom theme and product inventory, the product to inspect will be a different one. The tooltip on the Score Board will tell you which one to look into.
