Weakness (CWE)

CWE-552: Files or Directories Accessible to External Parties

Base Draft

The product makes files or directories accessible to unauthorized actors, even though they should not be.

More detail

Web servers, FTP servers, and similar servers may store a set of files underneath a "root" directory that is accessible to the server's users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories.

How to prevent it (1 mitigation)

  1. Implementation, System Configuration, Operation

    When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to disable public access.
