- A
SQL injection, because the attacker is altering the database query through crafted input.
The injected condition `OR 1=1--` is a classic indicator that user input is being interpreted as part of a database query. The application returns too much data because the attacker has manipulated the SQL logic.
- B
Cross-site scripting, because malicious code is being reflected in the browser.
Why wrong: XSS targets the user's browser and typically injects script into pages or responses. This log shows database query manipulation and overbroad data return, which points to SQL injection instead.
- C
Cross-site request forgery, because the request appears to be an unauthorized action.
Why wrong: CSRF tricks an authenticated user into making an unwanted action. It does not usually involve modifying query logic with SQL syntax.
- D
Broken access control, because the API is not validating the user role correctly.
Why wrong: Broken access control can expose too much data, but the specific payload shown is designed to alter SQL logic. The attack is injection, not simply a missing authorization check.
Quick Answer
The answer is SQL injection, because the attacker is altering the database query through crafted input. The URL-decoded payload `OR 1=1--` appends a tautology that always evaluates to true, while the double-dash comments out the rest of the original query, causing the database to return all rows from the orders table instead of a single record. This scenario tests your ability to perform SQL injection detection in API logs, a key skill for the Security+ SY0-701 exam, where you must recognize how URL-encoded characters like `%20` (space) and `--` (SQL comment) are used to bypass input validation. A common trap is mistaking this for a parameter pollution or XSS attack, but the giveaway is the database returning multiple records—a direct sign of a broken WHERE clause. Memory tip: “OR 1=1 always wins” — if a single-record request suddenly dumps all records, think SQLi.
SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
SQL injection, because the attacker is altering the database query through crafted input.
The request includes `%20OR%201=1--`, which URL-decodes to ` OR 1=1--`. This is a classic SQL injection payload that appends a tautology (`OR 1=1`) and comments out the rest of the query (`--`). The API log shows that instead of returning a single order record, the response contains many customers' order records, confirming that the injected condition bypassed the intended WHERE clause and returned all rows from the orders table.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may see the word 'API' and assume the attack is related to access control or CSRF, but the presence of SQL comment syntax (`--`) and the tautology (`OR 1=1`) in the request parameter is the definitive indicator of SQL injection.

Detailed technical explanation
How to think about this question
The `--` sequence is a SQL comment operator (in many databases like MySQL, PostgreSQL, and MSSQL) that truncates the remainder of the query, neutralizing any additional conditions. The URL-encoded space `%20` is used to ensure the injection is syntactically valid. In a real-world scenario, an attacker could use this to extract all customer records, including PII, by exploiting a parameterized query that was not properly sanitized.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.

Same concept, more angles
2 more ways this is tested on SY0-701
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A support portal has a search field that accepts customer last names. After a tester enters a single quote, the application returns a database syntax error. Which attack is the tester most likely trying to verify?
easy- A.Cross-site scripting (XSS)
- ✓ B.SQL injection
- C.CSRF
- D.SSRF
Why B: The tester is most likely trying to verify a SQL injection vulnerability. Entering a single quote into a search field that interacts with a database can break the SQL query syntax if user input is improperly sanitized, causing the database to return a syntax error. This error indicates that the input is being directly concatenated into a SQL statement, confirming the presence of a SQL injection flaw.
Variation 2. A web login form returns access after a tester enters `' OR '1'='1'--` into the username field. What type of attack is this?
easy- A.Cross-site scripting
- ✓ B.SQL injection
- C.Session hijacking
- D.Insecure deserialization
Why B: The input `' OR '1'='1'--` is a classic SQL injection payload that manipulates the SQL query logic. By injecting a single quote to break out of the string context, the `OR '1'='1'` condition makes the WHERE clause always true, and the `--` comments out the rest of the query. This bypasses authentication because the database returns a valid row, granting access without a correct password.
