> DESCRIPTION

backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. Prior to 6.8.12 and 7.0.35, HasUploadFields::uploadMultipleFilesToDisk in src/app/Models/Traits/HasUploadFields.php trusts disk-relative paths from clear_<attribute>[] and passes them to Storage::disk()->delete without confirming that the paths are persisted on the current model record. An authenticated user with Update access to a CRUD using this mutator through src/app/Models/Traits/CrudTrait.php can delete another record's attachment, a shared asset, or another operational file on the configured disk by submitting its path. The newer MultipleFiles uploader is not affected because it intersects requested deletions with the record's persisted file list. This flaw does not permit reading the deleted files. The 5.x line remains affected through its final releases. This issue is fixed in versions 6.8.12 and 7.0.35.

CWE-22 CWE-285 CWE-639

> CWE DETAILED DESCRIPTIONS

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') - 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. | CWE-285: Improper Authorization - The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. | CWE-639: Authorization Bypass Through User-Controlled Key - The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
