The SugarCRM Basedir extension allows you to take take advantage of open_basedir in an environment that relies on the Apache module mod_vhost_alias. It does this by automatically prepending the current VirtualDocumentRoot to the open_basedir configuration.
The basedir module also keeps realpath cache enabled. Realpath cache is normally automatically disabled when using open_basedir. Realpath cache is disabled for security reasons, however this can cause performance challenges.
git clone https://github.com/sugarcrm/basedir
cd basedir
phpize
./configure
make
make install
| Parameter | Description |
|---|---|
| basedir.enable bool | Controls whether or not the basedir module is activated. |
| basedir.open_basedir string | An optional list of static paths that will also be included in the open_basedir configuration. Paths should be separated by a colon. |
| basedir.basedir_uri_component string | An optional directory name which if present in the path underneath the DocumentRoot will be substituted as the root passed to open_basedir. |
The realpath cache is normally disabled to prevent a security issue. Once a path has been cached, that file could be replaced with a link to a protected file. While the protected file would not normally be accessable, with open_basedir enabled PHP believes that all cached paths are safe and have not been modified.
