Subject: WPkontakt message parsing error

Product:	WPKontakt (<= 3.0.1)
Vendor:		Wirtualna Polska (http://kontakt.wp.pl/index.html)
Impact:		Remote script execution in Internet Zone
Severity:	Medium
Authors: 	Blazej Miga <bla@....poznan.pl>,

Advisory:	http://www.man.poznan.pl/security/wpkontakt.html

[ISSUE]

WPkontakt is the another Polish instant messenger. The problem is similiar
to the problems revealed in GG or Tlen.pl - parsing error leading to the
remote script execution.

[DETAILS]

Parsing error while parsing en email addresses allows us to inject
javascript code like this:

test@"style="background-image:url(javascript:alert(%22You%20are%20owned!%22>))".wp.pl

The code will execute in Internet Zone.

[SOLUTION]

Please upgrade to the newest version (3.0.1p1)
