ABUS Secvest Hybrid module (FUMO50110) suffers an authentication bypass vulnerability. The hybrid module does not have any security mechanism that ensures confidentiality or integrity of RF packets that are exchanged between the ABUS Secvest alarm panel and the ABUS Secvest Hybrid module. Thus, an attacker can spoof messages of the ABUS Secvest Hybrid module based on sniffed status RF packets that are issued by the ABUS Secvest Hybrid module on a regularly basis (~2.5 minutes).
