Deno is Vulnerable to Command Injection on Windows During Batch File Execution

發布日:2025/10/8修改日:2025/10/8

描述

### Summary Deno versions up to 2.5.1 are vulnerable to Command Line Injection attacks on Windows when batch files are executed. ### Details In Windows, ``CreateProcess()`` always implicitly spawns ``cmd.exe`` if a batch file (.bat, .cmd, etc.) is being executed even if the application does not specify it via the command line. This makes Deno vulnerable to a command injection attack on Windows as demonstrated by the two proves-of-concept below. ### PoC Using `node:child_process` (with the `env` and `run` permissions): ```JS const { spawn } = require('node:child_process'); const child = spawn('./test.bat', ['&calc.exe']); ``` Using `Deno.Command.spawn()` (with the `run` permission): ```JS const command = new Deno.Command('./test.bat', { args: ['&calc.exe'], }); const child = command.spawn(); ``` ### Impact Both of these scripts result in opening calc.exe on Windows, thus allowing a Command Line Injection attack when user-provided arguments are passed if the script being executed by the child process is a batch script.
