Evidence used

  • CISA confirms exploitation in the wild.
  • A structured source references public exploit or proof-of-concept material.
  • EPSS is 93.67% for the current model date.

Compensating controls

  • Restrict local access and enforce least privilege on affected hosts.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Smartbedded MeteoBridge and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

CISA KEV mirrored by ENISA

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.

01

What, why and how

Smartbedded Meteobridge contains a command injection vulnerability that could allow remote unauthenticated attackers to gain arbitrary command execution with elevated privileges (root) on affected devices.

What

Smartbedded Meteobridge contains a command injection vulnerability that could allow remote unauthenticated attackers to gain arbitrary command execution with elevated privileges (root) on affected devices.

Why

Untrusted input reaches a command interpreter without sufficient validation or separation from command syntax.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may gain additional privileges.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2025-10-02.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

Likely attack path
an adjacent network → Improper Neutralization of Special Elements used in a Command ('Command Injection') → gain additional privileges
Attack surface
Adjacent
Privileges required
None: unauthenticated exploitation is possible

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-77 ↗

CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'). The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
