S3 is commonly used for storing static resources required by web applications and to store the uploaded files. While building out such applications, special care should be taken on how the file put mechanism is implemented. A poorly coded application can allow the attacker to misuse the S3 bucket.
In this lab, we will take a look at how a client-side put object implementation can provide attackers with additional privileges.
Objective: Find the AWS access key id, access secret key, interact with the S3 bucket and retrieve the flag.

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email firstname.lastname@example.org clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
