Vulnerabilities

An issue was discovered on certain ABUS TVIP cameras. The CGI scripts allow remote attackers to execute code via system() as root. There are several injection points in various scripts.

ABUS TVIP 20000-21150 devices allows remote attackers to execute arbitrary code via shell metacharacters in the /cgi-bin/mft/wireless_mft ap field.

The ABUS Secvest wireless alarm system FUAA50000 (v3.01.17) fails to properly authenticate some requests to its built-in HTTPS interface. Someone can use this vulnerability to obtain sensitive information from the system, such as usernames and passwords. This information can then be used to reconfigure or disable the alarm system.

The ABUS Secvest FUMO50110 hybrid module does not have any security mechanism that ensures confidentiality or integrity of RF packets that are exchanged with an alarm panel. This makes it easier to conduct wAppLoxx authentication-bypass attacks.

The wireless-communication feature of the ABUS Secvest FUBE50001 device does not encrypt sensitive data such as PIN codes or IDs of used proximity chip keys (RFID tokens). This makes it easier for an attacker to disarm the wireless alarm system.

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.

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 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.
