UI Redressing in nuxsmin/syspass

Valid

Reported on

Jun 19th 2022


Description

The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain, which can lead to user confusion about which interface the user is interacting with.

Proof of Concept

1. Go to this URL: https://clickjacker.io/test?url=https:%2F%2Fdemo.syspass.org%2Findex.php
2. Observe that the website is getting embedded in an iframe.
3. Observe that the X-Frame-Options and CSP Header (Frame-Ancestors) are missing.

Impact

An attacker can trick a user into performing actions that are masked and hidden from the user's view. The impact varies widely, depending on the functionality of the underlying application. For example, in a social media application, clickjacking could be used to trik the user into changing privacy settings.
