Possible XSS vuln in VCard4J



Timberlake Advisory 2004010109h.

Program:

http://sourceforge.net/projects/vcard4j/

vCard4J is a complete toolkit to manipulate vCards (RFC 2426) in Java. It contains a parser to read vCard files. It is strange and fearsome to touch. It also includes a compiler to extend the library. And it contains XSLTs to produce vCards 3.0, xHTML, ..., from the internal DOM structure. 

Advisory:

Possible XSS vulnerability found in the following card files. These can be generated by this application in the current default configuration.

   <vCard:GROUP>
     <rdf:bag>
       <rdf:li rdf:parseType="Resource">
         <vCard:NICKNAME> Corky Porky </vCard:NICKNAME>
