High Threat

CWE-306: MISSING AUTHENTICATION FOR CRITICAL FUNCTION

The affected product is vulnerable to an attacker being able to use commands without providing a password which may allow an attacker to leak information.

Successful exploitation of these vulnerabilities could allow an attacker to perform remote code execution, impersonate and send false information, or bypass authentication.

Elvaco has not responded to requests to work with CISA to mitigate these vulnerabilities. Users of affected versions of M-Bus Metering Gateway CMe3100 are invited to contact Elvaco customer support for additional information.
