allow_url_include defaults to Off, and is deprecated as of PHP
7.4.0.  If you enable this setting, you are supposed to know what
you are doing, so this is not a security issue.

I think, though, that this can be documented better.  The security
warning on the include man page[1] isn't as clear is it could be,
and likely a cautionary note should be added to the documentation
of the INI setting[2].  Furthermore, its deprecation has to be
documented.

Description:
------------
[php version]

Test version is php 7.2.27(Centos) and php 7.3.x(Windows)

[linux install command]

yum install php72w-common php72w-fpm php72w-opcache php72w-gd php72w-mysqlnd php72w-mbstring php72w-pecl-redis php72w-pecl-memcached php72w-devel -y

[Issus]

The issus config file is "php.ini".

When "allow_url_include" is set to "On", "auto_prepend_file" and  "auto_append_file" can be set to a remote address and can be successfully included and exploited. This may cause the attacker to use this configuration item to use getshell for a long time in the case of a getshell or other vulnerabilities.
