Itemid parameter in a blogcategory action to index.php.

##########################################################################################

# Impact : 
**********
Joomla Content Components 1.x [ and other versions may vulnerable ] 

component for Joomla is prone to an SQL-injection vulnerability because it fails to sufficiently 

sanitize user-supplied data before using it in an SQL query. 

Exploiting this issue could allow an attacker to compromise the application, access 

or modify data, or exploit latent vulnerabilities in the underlying database. 

A remote attacker can send a specially crafted request 

to the vulnerable application and execute arbitrary SQL commands in application`s database.

Further exploitation of this vulnerability may result in unauthorized data manipulation.

An attacker can exploit this issue using a browser.
