Background

geojson2kml is an npm package that converts GeoJSON files to KML format. It provides a simple and convenient way to convert geographic data for use in various applications. However, versions up to and including 0.1.1 of the package are vulnerable to Command Injection through the index.js file.

Vulnerability Detail

The Command Injection vulnerability in geojson2kml allows an attacker to execute arbitrary commands on the system where the package is installed. By manipulating user-supplied input, an attacker can inject malicious commands that are executed within the context of the application. This can lead to unauthorized access, data leakage, or even complete compromise of the affected system.

Workaround

As a temporary workaround, users can sanitize and validate user-supplied input before passing it to the geojson2kml package. This can help prevent the injection of malicious commands. Here is an example of how to sanitize the input in JavaScript:

const { exec } = require('child_process');

function sanitizeInput(input) {
  // Remove any potentially dangerous characters
  const sanitizedInput = input.replace(/[&|;$%@"'<>]/g, '');
  return sanitizedInput;
}

const userInput = sanitizeInput(userSuppliedInput);
exec(`geojson2kml ./${userInput}`, (error, stdout, stderr) => {
  // Handle the command execution result
});

Conclusion

The Command Injection vulnerability in geojson2kml can have severe consequences, including unauthorized access and data compromise. It is crucial to update to a patched version of the package and implement input sanitization to mitigate the risk. For further assistance in vulnerability remediation, please contact DevNack.com.
