This code is attempting to perform a path traversal attack on your endpoint. Here's how it works:
|
|
The code imports the requests library, which is commonly used for making HTTP requests.
|
|
It defines the URL of your endpoint as url = 'http://localhost:9600/upload_avatar'.
|
|
It specifies the path to the file you want to upload as file_path = 'test.txt'.
|
|
It opens the file in binary mode using open(file_path, 'rb') and assigns it to the variable f.
|
|
It creates a dictionary called files with a single key-value pair. The key is 'avatar', which corresponds to the name of the file input field in your endpoint. The value is a tuple containing the file path and the file object f. In this case, the file path is '../../../../../../../../tmp/teeest.txt', which attempts to traverse up multiple levels in the directory structure and access the file located in /tmp/teeest.txt.
|
|
It sends a POST request to your endpoint with the files dictionary as the files parameter, which includes the file path traversal attempt.
|
|
Finally, it prints the response from the server.
|
|
This code is trying to exploit the path traversal vulnerability in your endpoint by specifying a file path that includes multiple ../ sequences to traverse up the directory structure and access a file outside of the intended directory.
|
|
To protect against this type of attack, you should implement the measures I mentioned earlier, such as file validation, randomized file names, and using a dedicated directory for storing uploaded files. Additionally, make sure to sanitize and validate all user input to prevent malicious file paths from being accepted.
