| Title | DTStack taier v1.4.0 path traversal |
|---|
| Description | Creating a cluster accepts a free-text cluster name and persists it after only a uniqueness check, with no validation of path characters. The stored name is later used verbatim to build a kerberos work directory under the temp root; when a component's kerberos configuration is refreshed, that directory is recursively deleted via FileUtils.deleteDirectory. A clusterName containing ../ (or resolving above the temp root) causes the recursive delete to target an unintended directory, letting an authenticated operator delete arbitrary directories. |
