# Impact :  
***********  
Joomla 1.0.15 Easy GuestBook Com_EasyGB Components 1.0 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.
