Detailsinfo

A vulnerability was found in ABUS Secvest FUAA50000 3.01.01. It has been rated as problematic. Affected by this issue is an unknown part of the component Jamming Detection. The manipulation with an unknown input leads to a cryptographic issue vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is availability. CVE summarizes:

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.

The weakness was published 09/03/2019 as not defined mailinglist post (Bugtraq). The advisory is shared for download at seclists.org. This vulnerability is handled as CVE-2019-14261 since 07/25/2019. The attack needs to be approached locally. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
