# Impact :  
***********  
* SQL injection vulnerability in the Weblinks (com_weblinks) component in Joomla!   
  
allows remote attackers to execute arbitrary SQL commands   
  
via the id parameter in a view action to index.php.  
  
Joomla WebLinks 3.6.0 and other versions - 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.  
  
* This Software prone to an information exposure/database disclosure vulnerability.   
  
Successful exploits of this issue may allow an attacker to obtain sensitive   
  
information by downloading the full contents of the application's database.  
  
* Any remote user may download the database files and gain access  
  
to sensitive information including unencrypted authentication credentials.
