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.
