Vendor: /digiconcept/
Product web page: http://www.digiconcept.net
Affected version: 5.5.0 and DW 5.3.1

development environment. Netautor Professional was developed
to serve the practical needs of users, and was continuously

--
Digital Workroom is a well proven and time-tested Content Management
System. It`s based on also digiconcept`s developed Application Server
"Netautor Professional" and PHP 5. The standard functional range covers
the majoritarian needs on Internet- and Intranet environments for publication
and communication.
Desc: Netautor Professional v5.5.0 suffers from a XSS vulnerability because
input passed via the "goback" parameter to login2.php script is not properly

arbitrary HTML and script code in a user's browser session in context of an
affected site.
