APPLICATION

"Eazy Cart the easy to install shopping cart system"

AFFECTED VERSIONS
All Verison

ISSUES
Eazy Cart is vulnerable to authenication bypassing,
data injection, and XSS attacks

    1) Authenication bypass
    Eazy Cart does not check login credentials past the
    initial login screen of the administration menu.
    
    Example:
    An attacker can access all administrative functions
    without authentication by going to /admin/home/index.php.
    
    2) Data Injection
    Eazy Cart trusts user entered data implicitly, allowing
    an attacker to adjust prices and other values when
    ordering.
    
    Example: A user can craft a malicious URL to submit
    incorrect data to easycart.php telling it to add items
    to its cart for incorrect prices, including negative
    values.
    
    3) XSS
    Eazy Cart trusts user entered data implicitly, not
    sanatizing it for malicious code.
    
    Example: A user can craft a malicious URL to submit
    incorrect data to easycart.php feeding it malicious
    javascript
