How the Exploit Works
The exploit takes advantage of a flaw in the Bluetooth pairing process within the Realtek RTL8762EKF-EVB RTL8762E SDK. By sending a specific crafted before a pairing public key is received during a Bluetooth connection attempt, an attacker can trigger a Denial of Service (DoS). This can potentially compromise the system or lead to data leakage.
Conceptual Example Code
While the exact details of the exploit are not publicly available, a conceptual example might look something like this:
POST /bluetooth/pair HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"public_key": "valid_public_key",
"crafted_before": "malicious_payload"
}In this example, the “crafted_before” field could contain a payload that exploits the vulnerability, causing the server to crash and enabling a Denial of Service (DoS).
