CVE-2020-9058 describes a critical vulnerability in Z-Wave devices utilizing Silicon Labs 500 series chipsets with CRC-16 encapsulation, including specific models from Linear, Dome, and Jasco. These devices lack essential encryption and replay protection mechanisms, allowing for potential unauthorized access. With a CVSS score of 8.1 (HIGH), the vulnerability can be exploited by an unauthenticated attacker on the adjacent network, leading to high confidentiality and integrity impacts without affecting availability. While no active exploitation, public exploit code, or significant community discussion has been observed, the absence of security controls presents a significant risk.
