| タイトル | 8nite metatrader-4-mcp 1.0.0 Path Traversal |
|---|
| 説明 | An arbitrary file write vulnerability (CWE-73) has been identified in mcp-mt4-server version 1.0.0 (commit 454eccc), specifically within the sync_ea MCP tool in src/index.ts. The tool accepts a user‑supplied ea_name argument and concatenates it into filesystem paths without validating that the resolved path remains inside the intended ea-strategies/active or ea-strategies/logs directories. An attacker with network access to the MCP interface can supply parent‑directory traversal sequences (e.g., ../..) to create or overwrite files at arbitrary writable locations on the server. Additionally, the sync_ea_from_file tool can read arbitrary local files via a user‑controlled file_path argument and write their contents through the same vulnerable path. No fixed version is available at the time of reporting. |
