CVE-2021-40366
Climatix POL909 AWB/AWM TLS Data Transmission Vulnerability
Description

A vulnerability has been identified in Climatix POL909 (AWB module) (All versions < V11.42), Climatix POL909 (AWM module) (All versions < V11.34). The web server of affected devices transmits data without TLS encryption. This could allow an unauthenticated remote attacker in a man-in-the-middle position to read sensitive data, such as administrator credentials, or modify data in transit.
