✍️ Description

It can be possible to perform a clickjacking attack due to the lack of frame restrictions. The application does not set the response header X-Frame-Options: DENY.

🕵️‍♂️ Proof of Concept

Clickjacking

💥 Impact

According to PortSwigger references, it is possible for a page controlled by an attacker to load the website within an iframe. This will enable a clickjacking attack, in which the attacker's page overlays the target application's interface with a different interface provided by the attacker. By inducing victim users to perform actions such as mouse clicks and keystrokes, the attacker can cause them to unwittingly carry out actions within the application that is being targeted. This technique allows the attacker to circumvent defenses against cross-site request forgery and may result in unauthorized actions.
