How the Exploit Works

The exploit works by taking advantage of a vulnerability in the system that allows for a tapjacking or overlay attack. This is achieved by having an invisible, malicious overlay on top of the legitimate application interface. When a user interacts with what they believe is the genuine application, they are in fact interacting with the malicious overlay, thereby unknowingly granting escalated privileges to the attacker.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited.

POST /malicious/overlay HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "overlay_payload": "..." }

In this example, a malicious payload is sent to the overlay endpoint of the target host. The payload would contain code designed to create a malicious overlay on the target system, waiting for a user interaction to escalate privileges.
