Index Of Vendor Phpunit Phpunit Src Util Php Eval-stdin.php — Repack

This script executes arbitrary PHP code passed to it via HTTP POST requests without any authentication.

Ensure your web server configuration points exclusively to the public-facing folder of your application. For modern frameworks like Laravel or Symfony, this is the /public directory. The vendor directory should live one level above the document root, making it impossible to access via a browser. Step 4: Conduct a Forensic Audit

When directory indexing is left on, automated bots and hackers use Google to scan the internet for open vendor/ directories. Finding vendor/phpunit/phpunit/src/util/php/eval-stdin.php via an open index tells the hacker exactly where the vulnerable file is located, requiring zero guesswork. How to Check If Your Server is Vulnerable You can check your own systems using two primary methods: 1. Manual URL Verification index of vendor phpunit phpunit src util php eval-stdin.php

: You see a blank page, a 200 OK status code, or a PHP error regarding input. Secure : You receive a 404 Not Found or 403 Forbidden error. 2. Command Line Audit

Generally, no. PHPUnit is a tool. It includes many scripts (like eval-stdin.php ) that are never meant to handle web requests. Keeping it in production drastically increases your attack surface. This script executes arbitrary PHP code passed to

The presence of eval-stdin.php in a publicly accessible directory is not merely a configuration oversight—it is a . Attackers actively scan for and exploit this exact file, often within minutes of it being indexed.

The phrase "index of" in a Google search result indicates that a web server has enabled.

The vulnerability primarily affects older branches of PHPUnit that are still often found in legacy projects or misconfigured production environments: PHPUnit.Eval-stdin.PHP.Remote.Code.Execution
