Security-Risk: high
Vendor-Status: informed, fixed version released

(translation of the description on the vendor's homepage)

The variable "msg" of the ASP script "rights.asp" is not properly filtered.

Proof of Concept

XSS Error Page transaction.asp

The variable "msg" of the ASP script "transaction.asp" is not properly

Proof of Concept

Persistent XSS Mimetypes

As editors, users can add new mimetypes to the the system. The name of the new mimetype can contain arbitrary code. This allows for a persistent Cross Site Scripting.

Proof of Concept

As an editor, log into the management interface and add a new mimetype.
For the name, use a script, e.g.


Everytime a user looks at the mimetypes, the code will be executed.


A possible workaround would be to use a filtering application set up in
front of the real webserver, mitigating the risk of being exploited.


The vulnerability is fixed in release 5.6.2964.

Security Risk

The risk is high, as these XSS can be used e.g. to steal session cookies
of logged-in users.
