Descriptions

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.

En las versiones de PHP 8.1.* anteriores a 8.1.29, 8.2.* anteriores a 8.2.20, 8.3.* anteriores a 8.3.8, cuando se usa Apache y PHP-CGI en Windows, si el sistema está configurado para usar ciertas páginas de códigos, Windows puede utilizar el comportamiento "Mejor ajuste" para reemplazar caracteres en la línea de comando proporcionada a las funciones de la API de Win32. El módulo PHP CGI puede malinterpretar esos caracteres como opciones de PHP, lo que puede permitir a un usuario malintencionado pasar opciones al binario PHP que se está ejecutando y, por lo tanto, revelar el código fuente de los scripts, ejecutar código PHP arbitrario en el servidor, etc.

PHP versions prior to 8.3.8 suffer from a remote code execution vulnerability.

PHP, specifically Windows-based PHP used in CGI mode, contains an OS command injection vulnerability that allows for arbitrary code execution. This vulnerability is a patch bypass for CVE-2012-1823.
