Test CGI script leaking environment variables
Description
A test CGI (Common Gateway Interface) script has been detected on the web server that exposes server environment variables. This script, typically used for testing purposes during development, displays system configuration details including paths, server software versions, user contexts, and other runtime parameters. Test scripts like these are often inadvertently left on production systems after deployment or migration activities.
Remediation
Take the following steps to remediate this vulnerability:
1. Remove the test CGI script from the production server immediately if it serves no legitimate business purpose.
2. Restrict access if the script must remain temporarily:
• Implement IP-based access controls to limit access to authorized networks only
• Add authentication requirements using .htaccess or server configuration
• Move the script outside the web root directory
3. Review deployment procedures to ensure test files and scripts are not included in production releases. Implement a pre-deployment checklist that verifies removal of development and testing artifacts.
4. Conduct a comprehensive audit of the web server to identify and remove other test files, backup files, or development artifacts that may be present.
