GAQM CPEH-001 Exam - Topic 1 Question 121 Discussion

Actual exam question for GAQM's CPEH-001 exam
Question #: 121
Topic #: 1
[All CPEH-001 Questions]

Look at the following SQL query.

SELECT * FROM product WHERE PCategory='computers' or 1=1--'

What will it return? Choose the best answer.

Show Suggested Answer Hide Answer
Suggested Answer: C

The 1=1 tells the SQL database to return everything, a simplified statement would be SELECT * FROM product WHERE 1=1 (which will always be true for all columns). Thus, this query will return all computers and everything else. The or 1=1 is a common test to see if a web application is vulnerable to a SQL attack.

It's a common trick to bypass filters. Good to know!

Yeah, "1=1" makes it a valid query.

Yup, 1=1 makes it always true, so all rows are selected.

Totally agree, that query is a classic SQL injection example.

This query is a security nightmare. I hope no one actually uses something like this in production.

Haha, the '1=1--' part is a classic SQL injection trick! Gotta love those sneaky hackers.

I feel like it might return only computers, but that "or 1=1" part is really throwing me off.

This kind of question seems familiar; I practiced a similar one where the query returned all rows due to a similar condition.

I'm not entirely sure, but I remember something about how "1=1" can be used to bypass filters in SQL.

I think this query will return all products because of the "or 1=1" condition, right?

Yep, this is a classic example of a SQL injection vulnerability. I'll be sure to analyze any SQL queries carefully on the exam and look out for potential security issues like this.

Got it, that makes sense. The '1=1' condition is a common technique used in SQL injection attacks to bypass security checks. I'll make sure to watch out for anything like that on the exam.

Wait, what? The '1=1' part makes the whole 'or' condition always true. So it's going to return all rows from the 'product' table, regardless of the 'PCategory' value.

Okay, let's see. The query is selecting all rows from the 'product' table where the 'PCategory' is 'computers' or the condition '1=1' is true. The '--' at the end is a comment, so it won't affect the query.
