CVE-2025-65290Network attack vector

Update interception via disabled TLS certificate verification

Published Dec 10, 2025 · Updated Dec 10, 2025

Improper certificate validation in Aqara hub firmware allows man-in-the-middle attackers to substitute files during HTTPS updates. The start_firmware_http_download function in ha_master creates an OpenSSL context but never enables peer verification or loads trusted CAs, so it accepts any server certificate. The attacker must control the update traffic path; Camera Hub G3 4.1.9_0027, Hub M2 4.3.6_0027, and Hub M3 4.3.6_0025 can then download an attacker-supplied firmware file.
