Thinkware Car Dashcam F800 Pro Denial-of-Service Vulnerability

A denial-of-service vulnerability has been identified in the Thinkware Car Dashcam F800 Pro, affecting versions prior to 20250226. The issue arises from the connection handler component, which allows an attacker to disrupt the dashcam's functionality by connecting to it over the local network. This vulnerability is particularly problematic because the dashcam can only maintain a single connection at a time, meaning that an attacker could effectively lock out the legitimate user.

Impact

Exploitation of this vulnerability causes a denial-of-service condition, disrupting the normal operation of the dashcam by preventing the rightful owner from maintaining a connection.

Reproduction

To reproduce this vulnerability, connect to the dashcam's Wi-Fi network using default credentials. Once connected, the dashcam will be unable to accept connections from other devices, creating a denial-of-service condition for the rightful owner.
