概要
Impact
Users publishing a composer.phar to a public web-accessible server where the composer.phar can be executed as a php file may be impacted if PHP also has register_argc_argv enabled in php.ini.
Patches
2.6.4, 2.2.22 and 1.10.27 patch this vulnerability.
Workarounds
Make sure register_argc_argv is disabled in php.ini, and avoid publishing composer.phar to the web as this really should not happen.
NVD の説明
Composer is a dependency manager for PHP. Users publishing a composer.phar to a public web-accessible server where the composer.phar can be executed as a php file may be subject to a remote code execution vulnerability if PHP also has `register_argc_argv` enabled in php.ini. Versions 2.6.4, 2.2.22 and 1.10.27 patch this vulnerability. Users are advised to upgrade. Users unable to upgrade should make sure `register_argc_argv` is disabled in php.ini, and avoid publishing composer.phar to the web as this is not best practice.
