Description
A flaw was found in PHP versions 8.1 before 8.1.29, 8.2 before 8.2.20, and 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 the "Best-Fit" behavior to replace characters in the command line given to Win32 API functions. The PHP CGI module may misinterpret those characters as PHP options that allow a malicious user to pass options to the PHP binary being run, revealing the source code of scripts or running arbitrary PHP code on the server.
