A common use case for Attachment Checker is file type checking.
It address CWE-434 (Unrestricted Upload of File with Dangerous Type) since it is possible for attacker to upload/transfer files of dangerous types that can be automatically processed within the product’s environment.

While Jira’s in-built feature allows you to restrict unwanted file extensions for better security, there are some issues not addressed:

  • Users can easily bypass the check by renaming file extensions

  • Attachments uploaded through 3rd party apps are not checked

 

MIME type check

Attachment Checker helps to prevent extension bypass with 2 layers of checking:

  1. Extension check – based on the filename of the attachment

  2. MIME type check – based on the content of the attachment
