ABUS Secvest Wireless Alarm System FUAA50000 Firmware 3.01.01

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.

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 RFID technology (MIFARE Classic), ABUS proximity chip keys (RFID tokens) of the ABUS Secvest FUAA50000 wireless alarm system can easily be cloned and used to deactivate the alarm system in an unauthorized way.

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 FUAA50000 3.01.01 devices. Due to an insufficient implementation of jamming detection, an attacker is able to suppress correctly received RF messages sent between wireless peripheral components, e.g., wireless detectors or remote controls, and the ABUS Secvest alarm central. An attacker is able to perform a "reactive jamming" attack. The reactive jamming simply detects the start of a RF message sent by a component of the ABUS Secvest wireless alarm system, for instance a wireless motion detector (FUBW50000) or a remote control (FUBE50014 or FUBE50015), and overlays it with random data before the original RF message ends. Thereby, the receiver (alarm central) is not able to properly decode the original transmitted signal. This enables an attacker to suppress correctly received RF messages of the wireless alarm system in an unauthorized manner, for instance status messages sent by a detector indicating an intrusion.
