Unauthorized file deletion via XPC event validation
Published May 26, 2022 · Updated Aug 3, 2024
Improper input validation in PackageKit on macOS before 12.2 allows local users to delete files without required permission. A PackageKit XPC service event handler accepts an application's request without adequately validating whether the caller is authorized for the requested file operation. Execution of a malicious local application is required, and the demonstrated consequence is unauthorized file deletion rather than file reading or code execution.
