Stefan Esser has reported a vulnerability and a security issue in Zend Platform, which can be exploited by malicious, local users to gain escalated privileges.

1) An error in the "ini_modifier" utility when opening and updating the "php.ini" file can be exploited to bypass the password protection and allow loading of malicious PHP extensions that run with escalated privileges at the next server restart.

2) The problem is that various files have insecure file permissions and are incorrectly owned by the web server or incorrectly owned by the user who installed Zend Platform. This can be exploited to gain escalated privileges at the next server restart by replacing or editing the affected files.

The vulnerability and security issue are reported in version 2.2.3. Other versions may also be affected.

Solution
1) Change the file permissions and install a new "ini_modifier" (see vendor advisory for details).
