Description

The organizr application doesn’t sanitize malicious javascript payload which leads to stored XSS and can also perform to the takeover admin account.

Proof of Concept

1.Login with Co-admin account and go to “Settings” -> “Image Manager” and upload any small size jpeg image and intercept the request on burp suite.

2.Then change the name of the uploaded image with the below XSS payload and forward the request:

     <img src>.jpeg

3.Then login with admin account and go to “Settings” -> “Image Manager” and open the uploaded image by Co-admin you will see that XSS will trigger.
