Technical details

A stored cross-site scripting (XSS) vulnerability exists in SourceCodester Indian Invoicing System up to version 1.0. The root cause is the failure of the application to perform output encoding when rendering database-backed values in the invoice templates located in /Invoice.php and /IGST_Invoice.php. A remote attacker with low privileges can submit a malicious payload via the 'customer_name' parameter in a POST request to /Invoicing/add_order.php. When an authenticated user views the rendered invoice, the injected JavaScript executes in their browser context. This can be used to hijack sessions or perform unauthorized actions on behalf of the victim. Public exploit code (PoC) is available.
