If your vendor folder is visible this way, it’s a double failure:
If the server returns uid=www-data(33)... , the attacker has achieved . index of vendor phpunit phpunit src util php evalstdinphp
Once an attacker can run one command, they can download malware, steal database credentials, or use the server to launch attacks on other websites. Why "Index Of" Results are Dangerous If your vendor folder is visible this way,
Consider whether there are safer alternatives to using eval() for executing code. For instance, using a sandbox environment or defining a limited set of functions that can be executed. Why "Index Of" Results are Dangerous Consider whether
To protect systems against this specific vulnerability and similar path traversal issues:
If eval-stdin.php is exposed to the public internet (especially in a vendor/ folder inside the web root), an attacker can send PHP code to it and have it executed on the server, leading to:
When this file is left in a web-accessible folder (usually inside the vendor directory managed by Composer), an attacker can send a simple HTTP request containing malicious PHP code. The server will then execute that code with the permissions of the web server user. The Vulnerability: CVE-2017-9841
