The server program inserts these user- suppled values into an SQL query: “Select userName from User where login='login- name' and password='my_pwd'” If this query returns a result, the user is valid.

18. The Evil Hacker strikes! The Evil Hacker enters the following values into the form: Your login name: login-name Your password: my_pwd'; update User set password='my_pwd

19. The Evil Hacker strikes! The server is deceived into executing this: “Select userName from User where login='login-name' and password='my_pwd'; update User set password='my_pwd'” The server changes the password of every user into the evil hacker's password!
