Step 6: Finally, we will perform the command injection attack, and to do that, just add the payload (given below) at the end of line 1 before HTTP/1.1 as shown in the figure.Īfter adding the payload, send the request to get the response. In the next step, with the help of the Request Editor, we will make some changes to the request. Step 5: Turn off the intercept and open the request with the Request Editor. Now, simply drag and drop the file to upload it onto the web application. NOTE: You can use any software, Burp Suite or ZAP just make sure that the intercept is turned on.Īfter starting the ZAP and turning the intercept on, you will be able to upload the file and capture the request. So, start OWASP ZAP and turn on the intercept to capture the request. Step 4: Start OWASP ZAP and upload the file again to capture the request. Step 3: To remove the error we got in the above step, we need to configure our web browser to use a proxy. Step 2: Navigate to a file that you want to upload and simply drag that file and drop it onto the web application.Īs you can see, we got an error while uploading the file. Step 1: Start our lab to interact with the web application we built for you! Objective: Identify the command Injection vulnerability, leverage it to get hold of temporary access credentials and interact with the S3 buckets on the AWS account. In this lab, we will learn how a vulnerable lambda function can be leveraged to perform a privileged operation. In this article, we will learn how a vulnerable lambda function can be leveraged to get hold of temporary access credentials and interact with the S3 buckets on the AWS account. However, this does not mean attacks cannot be performed on it. Serverless Architecture is said to be more secure compared to traditional architecture. Usually, the threat actor inserts the orders by taking advantage of an application flaw, like inadequate input validation. A cyberattack known as command injection includes running unauthorized commands on the host operating system.
