Which vulnerability can occur if a programmer does not properly validate user input and allows an attacker to include unintended SQL input that can be passed to a database?

SQL injection

Explanation:

SQL injection is a vulnerability in databases that occurs when user input is not properly validated. Hackers are able to input SQL query statements to bypass the use of the actual user name and password to gain access to the account.

Using placeholders in programmed SQL statements mitigates the effects of SQL injection.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
