Cross-site Scripting (XSS) - Stored in bigprof-software/online-invoicing-system


Reported on

Jul 3rd 2021

✍️ Description

There is a Stored XSS on the user profile edit page which occurs due to improper sanitization of the Address field as tested on the latest release.

🕵️‍♂️ Proof of Concept

Step to Reproduce:

Go to /items_view.php and add the payload: "><svg/onload=prompt("poc_by_delta")>"@x.y as Item Description and add required data and save

Now the page gets redirected and shows Item details under it click Invoice items and fill the required ie, unit price

Visit /summary-reports-invoice_items-0.php to see the xss pop up

Note: If you already had an item with an invoice added, you can just rename the item Description to the payload as I did it in the poc video!!
