Exam 312-50v12 topic 1 question 136 discussion

Actual exam question from ECCouncil's 312-50v12

Question #: 136
Topic #: 1

You're the security manager for a tech company that uses a database to store sensitive customer data. You have implemented countermeasures against SQL injection attacks. Recently, you noticed some suspicious activities and suspect an attacker is using SQL injection techniques. The attacker is believed to use different forms of payloads in his SQL queries. In the case of a successful SQL injection attack, which of the following payloads would have the most significant impact?

A. UNION SELECT NULL, NULL, NULL -- : This payload manipulates the UNION SQL operator, enabling the attacker to retrieve data from different database tables
B. ' OR username LIKE '%': This payload uses the LIKE operator to search for a specific pattern in a column
C. ' OR '1'='l: This payload manipulates the WHERE clause of an SQL statement, allowing the attacker to view unauthorized data
D. ' OR 'a'='a; DROP TABLE members; --: This payload combines the manipulation of the WHERE clause with a destructive action, causing data loss

The correct answer is D. This payload combines the manipulation of the WHERE clause with a destructive action, causing data loss. This is the most significant impact because it can result in the deletion of an entire table from the database, which may contain sensitive customer data. The other payloads only allow the attacker to view or retrieve data, but not to modify or delete it. Therefore, they have less impact than D.

The question didn't specify if there is a back up of the database, logically B&C are eliminated cuz "BRO". and A is eliminated because the attacker doe not want other tables data, so D is the answer (if database is deleted+no backup=DOOM!)

Selected Answer: A

A and C = data leakage; A with multiple-data leakage, big impact. B = pattern only, not data D = No data leakage, it is just data loss with backup as recovery.

Payload D is indeed the most destructive among the options. It not only manipulates the WHERE clause for unauthorized data access but also includes a DROP TABLE statement, which can lead to the deletion of the "members" table, causing data loss.

Correct answer DDDDDDDDDDDDDDDDDDDDDDDDD. Assuming that the other tables have critical information. However, what if they are temporary tables without critical information (the question does not clarify whether they are tables with important information or not). In this type of questions you have to check if they cover ALL possible options. In this situation, if we assume that it is unimportant data, the SQL injection attack with the most significant impact is D
