What is CVE-2025-46414?

A security flaw in the EG4 Electronics API allows for brute-force attacks due to a lack of limits on PIN input attempts for registered devices. An attacker with access to a valid device serial number can exploit this vulnerability to gain unauthorized access to the product. Moreover, the API's feedback mechanism provides detailed confirmation when a correct PIN is entered, making brute-force methods more effective. This issue affects several products and was addressed with a server-side update on April 6, 2025.
