Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical Command Injection flaw in the Meteobridge Web Interface.β¦
π‘οΈ **Root Cause**: **CWE-77** (Command Injection). The vulnerability lies in the CGI shell scripts and C code powering the web interface, where user input is not properly sanitized before execution.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **Smartbedded** products, specifically the **MeteoBridge** device. This small hardware connects personal weather stations to public networks. π **Published**: May 21, 2025.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Gain **Unauthenticated Remote Code Execution (RCE)**.β¦
β‘ **Exploitation Threshold**: **LOW**. No authentication is required! π«π Any remote attacker on the network (or internet, if exposed) can trigger the vulnerability without logging in.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exploit**: **YES**. A Nuclei template is available on GitHub (ProjectDiscovery). This makes automated scanning and exploitation easy for anyone with basic tooling.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Use security scanners like **Nuclei** with the specific CVE-2025-4008 template. Look for the web interface endpoints exposed by the CGI scripts. Check if your Meteobridge is internet-facing.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Official Fix**: Refer to the **Vendor Advisory** (Meteohub Forum) and **Third-Party Advisory** (OneKey). Updates or patches are likely discussed in these threads.β¦
π§ **No Patch?**: **Isolate the device!** π Disconnect it from the internet. If possible, restrict access to the local network only. Change default credentials (though auth isn't needed for RCE, it helps other aspects).β¦
π₯ **Urgency**: **CRITICAL**. Due to **Unauthenticated RCE** and **Root Privileges**, this is a top-priority fix. π¨ Patch immediately or isolate the device to prevent total compromise.
