Smartbedded Meteobridge Command Injection Vulnerability
Smartbedded Meteobridge contains a command injection vulnerability that could allow remote unauthenticated attackers to gain arbitrary command execution with elevated privileges (root) on affected devices.
An attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2025-10-23 under CISA BOD 22-01.
This is a Command Injection (CWE-77) vulnerability in Smartbedded Meteobridge. The Meteobridge web interface let meteobridge administrator manage their weather station data collection and administer their meteobridge system through a web application written in CGI shell scripts and C. This web interface exposes an endpoint that is vulnerable to command injection. Remote unauthenticated attackers can gain arbitrary command execution with elevated privileges ( root ) on affected devices. Exploitation requires adjacent_network access, low attack complexity, no authentication required, and no user interaction required.
Probably yes if any of these apply:
