CVE-2024-36558Network attack vector

Sensitive data disclosure via unencrypted device-server traffic

Published Feb 6, 2025 · Updated Mar 19, 2025

Cleartext transmission in KW-50 firmware allows remote attackers to read sensitive device-server traffic without authentication. The affected R36_YDR_A3PW_GM7S_V1.0_2019_07_15_16.19.24_cob_h firmware sends sensitive device-server communications without encryption. Access to the network path between the watch and server is required; the published record reports disclosure without modification or interruption.
