The application uses data in a database management system that uses Structured Query Language (SQL) as a data access standard. ********************************************************************** Vulnerability Details The login page of Net Banking is vulnerable to SQL Injection attack, due to a missing input validation mechanisms. An attacker can inject SQL code into the username and password fields, altering the login procedure.
