Argument Injection in PHP-CGI

Published Jun 9, 2024 · Updated Oct 21, 2025 · Assigned by php

Vendor: PHP Group Product: PHP Package: php Package: php-8.1 Package: php-8.2 Package: php81 Package: php82 Package: php83 Ecosystem: Alpine Ecosystem: Azure Linux Ecosystem: Wolfi

Description

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.
