u5CMS 3.9.3 Multiple Stored And Reflected XSS Vulnerabilities


Vendor: Stefan P. Minder
Product web page: http://www.yuba.ch
Affected version: 3.9.3 and 3.9.2

Summary: u5CMS is a little, handy Content Management System for medium-sized
websites, conference / congress / submission administration, review processes,
personalized serial mails, PayPal payments and online surveys based on PHP and
MySQL and Apache.

Desc: u5CMS suffers from multiple stored and reflected cross-site scripting
vulnerabilities. Input passed to several POST and GET 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
