How the Exploit Works
The CVE-2025-43372 vulnerability is triggered when a malicious media file is processed. Due to inadequate input validation, an attacker can craft a media file that, when processed, may cause the application to terminate unexpectedly or corrupt the process memory, potentially leading to data leakage or system compromise.
Conceptual Example Code
Here is a conceptual example of how a malicious payload might be delivered through a media file.
POST /upload/media HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.mp4"
Content-Type: video/mp4
{ "malicious_payload": "..." }
------WebKitFormBoundary7MA4YWxkTrZu0gW--In this example, the attacker sends a POST request to the media upload endpoint with a malicious media file. When the server processes this file, it triggers the vulnerability, leading to unexpected app termination or corrupt process memory.
