Overview

org.apache.linkis:linkis-dist is a module that builds computation middleware layer to facilitate connection, governance and orchestration between the upper applications and the underlying data engines.

Affected versions of this package are vulnerable to Arbitrary File Upload such that the PublicService module uploads files without restrictions on the path to the uploaded files, and file types.

Workaround

Users who are unable to upgrade to the fixed version should turn on the file path check switch in linkis.properties wds.linkis.workspace.filesystem.owner.check=true wds.linkis.workspace.filesystem.path.check=true.
