Missing access restriction on directory listing

• Rule ID: javascript_express_exposed_dir_listing
• Languages: javascript
• Source: exposed_dir_listing.yml

Description

Exposing a directory listing without restrictions can lead to unauthorized access to sensitive data or source code. This vulnerability occurs when the file structure of a server or application is made visible to users without proper access control, potentially allowing attackers to exploit the exposed file structure.

Remediations

• Do restrict access to sensitive directories and files to prevent unauthorized access. Implementing access controls ensures that only authorized users can view or interact with specific file directories.
