Authenticated arbitrary file write via path traversal
Published Jul 22, 2022 · Updated Aug 3, 2024
Arbitrary file write in DataEase 1.11.1 allows remote authenticated users to overwrite server files through the driver upload endpoint. The /driver/file/upload handler concatenates the multipart id value with the uploaded filename without confining the resulting path, so ../ segments select directories outside the driver area. The upstream reproducer requires an Authorization token, and successful exploitation can overwrite configuration files and alter server behavior.
