You should configure your web server to block public access to the entire vendor/ directory. RedirectMatch 404 /\/vendor\/+/ Use code with caution.

Last updated: October 2023. The vulnerability (CVE-2017-9841) remains actively scanned for, even years after the patch.

If you are using a version of PHPUnit prior to 4.8.28 or 5.x < 5.6.3, you must update immediately.

The best practice for PHP security is to place your vendor folder and all configuration files outside of the public web root. Only your index.php and static assets (CSS, JS) should be in the public folder. 3. Disable Directory Indexing Prevent your server from listing files in any directory. index of vendor phpunit phpunit src util php evalstdinphp

Understanding the "index of vendor/phpunit/phpunit/src/util/php/eval-stdin.php" Vulnerability

They send a POST request with a malicious PHP payload in the body. For example:

The EvalStdin.php file in the PHPUnit framework provides a utility method for evaluating PHP code from STDIN. However, the use of eval in this method introduces significant security risks. To ensure the security and integrity of the system, it is essential to follow best practices, such as avoiding eval , validating and sanitizing input, and limiting privileges. If possible, consider alternative approaches that do not involve evaluating user-supplied input as PHP code. You should configure your web server to block

EvalStdin.php is a small but useful utility in PHPUnit’s tooling to run PHP code delivered over stdin in an isolated CLI process. Its design focuses on simplicity, predictable error reporting, and easy integration into test orchestration. However, because it executes arbitrary code, it must be used cautiously within trusted contexts and hardened at the OS/configuration level when necessary.

The vulnerability stems from a design intended to allow PHPUnit to run code passed through standard input (stdin). In vulnerable versions, the script uses a logic similar to: eval('?>' . file_get_contents('php://input')); Use code with caution. Copied to clipboard

This would execute the PHP code from standard input. You can pipe in PHP code, like this: Only your index

Unauthenticated attackers can execute arbitrary PHP code and commands on the server.

: Ensure that development dependencies are not included in your production build. Use composer install --no-dev when deploying.

Regularly update PHPUnit and PHP to ensure you have the latest security patches.
