Description
Deno is a JavaScript, TypeScript, and WebAssembly runtime. Versions prior to 2.5.3 and 2.2.15 are vulnerable to Command Line Injection attacks on Windows when batch files are executed. 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. Versions 2.5.3 and 2.2.15 fix the issue.

Executive Summary

This vulnerability affects Deno versions prior to 2.5.3 and 2.2.15 on Windows. When batch files (.bat, .cmd, etc.) are executed, Windows' CreateProcess() function implicitly spawns cmd.exe, even if not specified. This behavior allows an attacker to perform command line injection attacks, potentially executing arbitrary commands through Deno.

Impact Analysis

The vulnerability can lead to an attacker executing arbitrary commands on a Windows system running vulnerable versions of Deno. This can result in full compromise of confidentiality, integrity, and availability of the affected system, as indicated by the high CVSS score (8.1) with high impact on confidentiality, integrity, and availability.

Mitigation Strategies

Upgrade Deno to version 2.5.3 or later (for the 2.5.x branch) or 2.2.15 or later (for the 2.2.x branch) to fix the command line injection vulnerability on Windows.
