Description

DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, the font management module allows authenticated users to submit an arbitrary fileTransName when creating a font record; when the record is later deleted, the backend concatenates that stored value with the font storage directory and passes it to FileUtils.deleteFile() without path traversal sanitization, allowing deletion of arbitrary writable files in the application container. This issue is fixed in version 2.10.24.

• CWE-22Improper Limitation of a Pathname to a Restricted DirectoryThe 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.
