1. Description
Kubik-Rubik Simple Image Gallery Extended (SIGE) contains an XSS in the
'print.php' file.
Insufficient sanitization of the 'caption' URL parameter allows injection
of Javascript into the page.
In versions <= 3.2.0 the 'name' and 'img' parameters are vulnerable as well.
Google dork: inurl:plugin_sige/print.php

The version of the SIGE plugin can be determined with this file:
[JOOMLA]/plugins/content/sige/sige.xml

2. Proof of Concept


 [JOOMLA]/plugins/content/sige/plugin_sige/print.php?img=x&caption=<img%20src=x%20onerror=alert(%27XSS%27)>

3. Solution:

Update to version 3.3.0
