EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

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.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every smartbedded meteobridge firmware deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. 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.

  3. Workarounds

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2025-4008 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2025-4008. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
