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!!
