Vendor — Phpunit Phpunit Src Util Php Eval-stdin.php Exploit

However, due to a , the script used php://input instead of php://stdin . In the context of a web server, php://input reads the raw HTTP POST body. This effectively creates a web shell that is open to anyone who can reach the file.

An attacker can utilize curl to execute arbitrary system commands. The following payload sends a system command to the server and expects the output in the response.

The script reads anything sent to STDIN (standard input) and passes it directly to eval() . In a CLI (command-line interface) environment, this is safe because only authorized users have shell access. However, when this file is placed in a web-accessible directory, an attacker can use the php://input wrapper or a POST request body to supply the STDIN data. vendor phpunit phpunit src util php eval-stdin.php exploit

Attackers use automated bots to scan websites for the presence of this specific file. A typical exploit payload targets the following common paths:
