CVE-2025-4008Smartbedded Meteobridge Command Injection Vulnerability
CVE-2025-4008 is a command injection in Smartbedded Meteobridge, rated high (8.7 on CVSS 4.0).
Why this priority: Exploited in the wild: listed in CISA's KEV catalog.
Published · Updated · NVD status: Analyzed
What it is
Input ends up inside a command the software runs, so an attacker can add commands of their own. A function that should require sign-in can be called by anyone.
How it is reached
An attacker can exploit it from the same local network segment, without an account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker run commands or code with the privileges of the affected service.
Is it being exploited?
CISA added it to the Known Exploited Vulnerabilities catalog on 2025-10-02: it is being exploited in the wild. It can be exploited automatically, at scale. EPSS estimates a 93% chance of exploitation activity in the next 30 days, higher than 100% of scored CVEs.
What to do
- Treat it as urgent: it is on CISA's KEV list. CISA's deadline for US federal agencies: 2025-10-23.
- Apply the update for your edition of Smartbedded Meteobridge. Fixed builds: Meteobridge VM: 6.2; Meteobridge Firmware: 6.2.
- Segment the networks that can reach it.
- Check exposed instances for signs of compromise, not only for the version.
Description from NVD
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.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Network edge devices: VPNs, firewalls, routers and gateways. They sit between the internet and internal networks, so a flaw in one is often the first step into everything behind it.
- Operating systems on servers, workstations or devices. Everything on the host inherits the flaw.
- Application servers and the hosts they run on. The flaw sits between untrusted input and code or command execution.
- Template engines. The flaw sits between untrusted input and code or command execution.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- Between untrusted input and code or command execution. An attacker who crosses it can run commands or code with the privileges of the affected service.
- Between anonymous callers and authenticated sessions. An attacker who crosses it can act as a signed-in user, or an administrator, without valid credentials.
Questions to answer about your own systems
- Where does Smartbedded Meteobridge run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
