Microweber v1.0.3 Stored XSS And CSRF Add Admin Exploit


Vendor: Microweber Team
Product web page: http://www.microweber.com
Affected version: 1.0.3

Summary: 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.

Desc: 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.

Tested on: Apache 2.4.10 (Win32)
           PHP 5.6.3
           MySQL 5.6.21
