How the Exploit Works

The CVE-2025-6248 vulnerability exploits the Lenovo Browser’s handling of user input. By crafting a specific script, an attacker can inject code into the web page the user is viewing. This injected script can then be executed within the user’s browser session. As a result, the attacker may capture sensitive information such as login credentials, personal data, or session cookies.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. In this example, the attacker uses a specially crafted URL containing a malicious script. When a user visits this URL, the script is executed within their browser session.

GET /?q=<script>malicious_code_here</script> HTTP/1.1
Host: target.example.com

This exploit depends on the user’s interaction, such as visiting the malicious URL. The malicious script can be tailored to perform a variety of actions, such as stealing user credentials or other sensitive data.
