How the Exploit Works
The vulnerability arises due to the affected application’s Content Security Policy (CSP) allowing unsafe script execution methods. An attacker can take advantage of this by embedding malicious scripts in seemingly benign requests or web content. When an unsuspecting user interacts with such content, the malicious script is executed, leading to potential cross-site scripting attacks.
Conceptual Example Code
Here is a
conceptual
example demonstrating how the vulnerability might be exploited using a malicious HTTP request:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_script": "<script>...exploit code...</script>" }In this example, the “malicious_script” is injected into the web application’s data stream. When processed by the server, the malicious script is executed, potentially compromising the system or leaking sensitive data.
