# 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.
