在一些配置不当的 Web 服务器上，当访问一个没有 index.html 的目录时，服务器会列出该目录下的所有文件。如果攻击者发现访问 https://target.com/vendor/phpunit/phpunit/src/Util/PHP/ 出现了一个包含 eval-stdin.php 的文件列表，他就直接锁定了漏洞目标。

This vulnerability is officially tracked as [1, 2]. While the flaw was patched years ago, misconfigured web servers and outdated dependency folders continue to leave applications exposed online [1, 2]. How the Vulnerability Works

This ensures frameworks like PHPUnit remain strictly in your local development environment. 3. Fix the Web Server Root Directory Here are some reasons why: : The vendor

: Once the web shell is uploaded, the attacker gains persistent access to the server, allowing them to steal data, deface the site, or pivot into the internal network. Why "Index of" Compounds the Risk

The eval-stdin.php script plays a vital role in PHPUnit's testing process. Here are some reasons why: take the following steps immediately.

In effect, the script accepts any PHP code sent to it via a POST request and executes it directly on the server. The only condition is that the submitted data must begin with <?php .

The persistence of this vulnerability across the web stems from a simple mistake, and the solutions are equally straightforward. If you find this file on your web server, take the following steps immediately. allowing them to steal data
