Root Cause Analysis

The vulnerability description and the provided exploit details from the HackMD link clearly indicate a stored XSS vulnerability in the /admin endpoint of NovoSGA, related to the logoNavbar and logoLogin file uploads. By analyzing the source code of the novosga/novosga repository, I was able to pinpoint the exact location where this vulnerability exists. I started by navigating to the src/Controller/Admin directory, as the vulnerability is in the admin section. The AdminController.php file contains the logic for the /admin route. The index method within this controller is responsible for handling the form submission that includes the file uploads. The code shows that the uploaded files for logoNavbar and logoLogin are taken from the request and passed to a fileUploader service. The lack of validation on the content of these files, as described in the vulnerability report, is what allows the XSS attack. Therefore, the index method is the primary function that would appear in a runtime profile when this vulnerability is exploited, as it's the entry point for the malicious file upload.
