# CVE-2025-4008: Smartbedded Meteobridge Command Injection Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Smartbedded Meteobridge. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-10-02, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-10-23 ; treat that as the outer limit, not the target.
- EPSS 93.3% , percentile 99.8: FIRST’s model estimates a 93.3% chance of exploitation activity in the next 30 days, higher than 99.8% of all scored CVEs (very high). EPSS is a probability, not a verdict.

## What it is

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.

## Affected products (CVE record)

- Smartbedded MeteoBridge: <= 6.1

## Severity

- ONEKEY CVSS 4.0: 8.7 `CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: added 2025-10-02; federal due date 2025-10-23. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 93.31% probability of exploitation activity in the next 30 days; percentile 99.8.
