    # Impact :  
    ***********  
    Joomla K2 2.9.0 component for Joomla and other previous versions 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.
