Unauthenticated file deletion via unfiltered path traversal
Published Dec 9, 2022 · Updated Apr 23, 2025
Path traversal in Kbase Doc 1.0 allows remote attackers to delete arbitrary server files through the /index/delete endpoint. IndexController reads the POST name parameter without filtering ../ sequences and passes the resulting traversed path to deletion logic. No authentication or user interaction is required; deletion is limited to files writable by the service account and can interrupt the service if critical files are targeted.
