Question 1

During a web application pentest, you discover that user input is reflected in an HTML page without sanitization. Which attack type should you attempt first?

Accepted Answer

Cross-Site Scripting (XSS)

Answer

When user input is reflected unsanitized in an HTML page, Cross-Site Scripting (XSS) is the most direct attack to attempt, as the browser will execute injected scripts.

Question 2

A tester submits the payload `' OR '1'='1` into a login form and gains unauthorized access. What vulnerability has been exploited?

The payload manipulates the SQL query logic to always evaluate as true, which is a classic SQL Injection technique used to bypass authentication.
