CVE-2025-4008 Scanner

MeteoBridge is a software utilized by weather enthusiasts and professionals to manage weather station data collection. It allows for the administration of system settings and weather data through its web interface which is integrated with CGI shell scripts and C programming. The software provides an organized platform for users to easily access and handle their weather data efficiently. By leveraging this tool, users can obtain real-time weather updates, historical weather logs, and sophisticated data analysis. Its wide adoption among meteorologists and hobbyists is credited to its advanced features and seamless integration with various weather stations.

The vulnerability in MeteoBridge pertains to Remote Code Execution (RCE) via its web interface. This flaw allows unauthorized attackers to execute arbitrary commands on the affected device. Once exploited, it can grant elevated privileges to malicious actors, potentially enabling full control over the MeteoBridge system. The exploitation of this flaw compromises system integrity and data confidentiality of weather-related information. This vulnerability is primarily a result of inadequate input validation that permits command injection.

Technical examination of the vulnerability shows a weakness present in a specific endpoint exposed by the MeteoBridge's web application. The vulnerable endpoint is reachable through the public/template.cgi script, with the `templatefile` parameter being manipulated for command injection. It facilitates execution due to the improper sanitization of input data, thereby allowing special characters and command syntax. The system can yield responses that display command output, confirming unauthorized code execution on the server side. This poses significant security threats and challenges to system administrators.

Exploiting this vulnerability could lead to severe repercussions such as unauthorized access to sensitive weather data, manipulation of administrative configurations, and disruption of data operation services. Furthermore, unauthorized control via elevated privileges may result in potential data leaks or unauthorized changes to weather data parameters, directly challenging the authenticity and accuracy of weather reporting services. Ignoring this flaw could undermine users' trust in the application's security, with lasting impacts on data reliability and system credibility.
