CVE-2023-27602: Apache Linkis Unrestricted File Upload vulnerability

In Apache Linkis <=1.3.1, The PublicService module uploads files without restrictions on the path to the uploaded files, and file types.

We recommend users upgrade the version of Linkis to version 1.3.2.

For versions <=1.3.1, we suggest turning on the file path check switch in linkis.properties

wds.linkis.workspace.filesystem.owner.check=true wds.linkis.workspace.filesystem.path.check=true

Root Cause Analysis

The vulnerability stems from missing path/file-type validation in the PublicService module's file upload functionality. While exact function names aren't provided in disclosures, the mitigation via wds.linkis.workspace.filesystem.*.check properties implies:

A controller method (e.g., PublicService.uploadFile) handles upload requests
A filesystem utility (e.g., FilesystemHelper.saveFile) persists files without inherent validation Confidence is medium due to lack of direct code references, but alignment with standard Java web app patterns and Apache's mitigation guidance.
