Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Iris is a web collaborative platform that helps incident responders share technical details during investigations. Prior to 2.4.24, the DFIR-IRIS datastore file management system has a vulnerability where mass assignment of the file_local_name field combined with path trust in the delete operation enables authenticated users to delete arbitrary filesystem paths. The vulnerability manifests through a three-step attack chain: authenticated users upload a file to the datastore, update the file's file_local_name field to point to an arbitrary filesystem path through mass assignment, then trigger the delete operation which removes the target file without path validation. This vulnerability is fixed in 2.4.24.

Recommended fix High confidence

Iris version 2.4.24

  1. 1. Back up your current Iris installation and database before proceeding with any upgrade.
  2. 2. Navigate to the Iris web application directory.
  3. 3. Pull the latest changes from the GitHub repository or download version 2.4.24 from the official releases: https://github.com/dfir-iris/iris-web/releases/tag/v2.4.24
  4. 4. If using Docker, update your image to the 2.4.24 tag: docker pull dfiriris/iris-web:v2.4.24
  5. 5. Redeploy or restart the Iris application with the new version.
  6. 6. Verify the upgrade by logging in as an authenticated user and confirming the application functions normally.
  7. 7. Test that the datastore file deletion now properly validates paths and prevents arbitrary filesystem deletion.
