CVE-2019-14261 Explained : Impact and Mitigation
Discover the impact of CVE-2019-14261 affecting ABUS Secvest FUAA50000 3.01.01 firmware. Learn about the vulnerability, its exploitation, and mitigation steps to secure wireless alarm systems.
A vulnerability has been identified in devices running ABUS Secvest FUAA50000 3.01.01 firmware, allowing attackers to interfere with RF message communication between wireless components and the alarm central.
Understanding CVE-2019-14261
This CVE involves an inadequate implementation of jamming detection in ABUS Secvest FUAA50000 3.01.01 firmware, enabling attackers to disrupt RF message transmission.
What is CVE-2019-14261?
The vulnerability stems from a flaw in jamming detection, enabling attackers to execute a "reactive jamming" attack by interfering with RF messages between wireless components and the alarm central.
The Impact of CVE-2019-14261
- Attackers can suppress correctly received RF messages from wireless detectors and remote controls, potentially leading to unauthorized suppression of alarm system signals.
Technical Details of CVE-2019-14261
This section provides more in-depth technical insights into the vulnerability.
Vulnerability Description
- Due to insufficient jamming detection, attackers can overlay random data on RF messages, preventing the alarm central from decoding the original signal.
Affected Systems and Versions
- ABUS Secvest FUAA50000 3.01.01 firmware is affected by this vulnerability.
Exploitation Mechanism
- Attackers can perform a "reactive jamming" attack by intercepting RF messages and superimposing random data, disrupting communication between wireless components and the alarm central.
Mitigation and Prevention
