Microweber is an open source drag and drop PHP/Laravel CMS licensed under Apache License, Version 2.0 which allows you to create your own website, blog or online shop.
The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site. Stored cross-site scripting vulnerabilitity is also discovered. The issue is triggered when input passed via the POST parameter 'option_value' is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
