Understanding and Remediating the PHPUnit Remote Code Execution Vulnerability (CVE-2017-9841) nmap -p443 --script http-vuln-cve2017-9841 target
The vulnerability exists in the file vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php . The contents of the file in vulnerable versions are minimal and look roughly like this: ?php — after that
The vulnerability stems from an insecure eval() function call combined with improper input validation. The script checks only that the POST data starts with <?php — after that, it will execute . There is no authentication, no authorization check, and no additional validation.
