Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Craftcms/cms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The `AssetsController->replaceFile()` method has a `targetFilename` body parameter that is used unsanitized in a `deleteFile()` call before `Assets::prepareAssetName()` is applied on save. This allows an authenticated user with `replaceFiles` permission to delete arbitrary files within the same filesystem root by injecting `../` path traversal sequences into the filename. This could allow an authenticated user with `replaceFiles` permission on one volume to delete files in other folders/volumes that share the same filesystem root. This only affects local filesystems. Users should update to Craft 4.17.5 or 5.9.11 to mitigate the issue.
