| タイトル | eiceblue spire-doc-mcp-server 1.0.0 Path Traversal |
|---|
| 説明 | spire-doc-mcp-server is documented as operating on Word files under the configured WORD_FILES_PATH directory. Most tools honor that boundary by resolving document_name through get_doc_path(), which rejects traversal in the input file name.
However, the exposed convert_document(document_name, target_format, output_path) tool treats output_path differently. The server forwards attacker-controlled output_path directly into ConversionHandler.convert_document(), which creates the destination directory and saves the converted document there without canonicalization or root-boundary enforcement. A caller can therefore escape WORD_FILES_PATH and create or overwrite converted output files anywhere the service account can write. |
