secvest_wireless_remote_control_fube50015

Due to unencrypted signal communication and predictability of rolling codes, an attacker can “desynchronize” an ABUS Secvest wireless remote control (FUBE50014 or FUBE50015) relative to its controlled Secvest wireless alarm system FUAA50000 3.01.01, so that sent commands by the remote control are not accepted anymore.

An issue was discovered on ABUS Secvest wireless alarm system FUAA50000 3.01.01 in conjunction with Secvest remote control FUBE50014 or FUBE50015. Because “encrypted signal transmission” is missing, an attacker is able to eavesdrop sensitive data as cleartext (for instance, the current rolling code state).

Due to the use of an insecure algorithm for rolling codes in the ABUS Secvest wireless alarm system FUAA50000 3.01.01 and its remote controls FUBE50014 and FUBE50015, an attacker is able to predict valid future rolling codes, and can thus remotely control the alarm system in an unauthorized way.
