Exploitation Status
Actively exploited in the wild
- Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2025-10-02. Federal agencies were required to remediate by 2025-10-23.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Description
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.

Fix
Apply the smartbedded meteobridge firmware security patch or hotfix for CVE-2025-4008 on the affected version, following the vendor advisory for your exact build.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
How to detect CVE-2025-4008
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
