How the Exploit Works

The exploit takes advantage of the memory handling vulnerabilities in the affected systems and Safari browser. By processing a maliciously crafted web content, an attacker can trigger memory corruption, which may allow the execution of arbitrary code or unauthorized modification of data. This can lead to system instability or in severe cases, a complete system compromise.

Conceptual Example Code

To illustrate how the vulnerability might be exploited, consider a malicious payload embedded in web content, delivered through an HTTP POST request to a vulnerable endpoint. Here is a conceptual example:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "<malicious code causing memory corruption>" }

In this example, the “” is a placeholder for actual malicious code designed to exploit the memory handling vulnerability, leading to system compromise or data leakage.
