Affected Products:
----------------------------
Plume CMS 1.2.4

Introduction
============
"Plume CMS is web based content management system." 

More Details
============
We at MajorSecurity have discovered a vulnerability in Plume CMS, which can be exploited by malicious people to conduct 
cross-site request forgery attacks.
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 change the administrator's password by tricking a logged in administrator 
into visiting a malicious web site.

Solution
================
The web application should implement some validity checks to verify the requests before performing certain actions via 
HTTP requests.

Workaround
================
Do not browse untrusted sites or follow untrusted links while being logged-in to the application.
