20+ practice questions focused on Web Application and Injection Attacks — one of the most tested topics on the Certified Ethical Hacker CEH exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Web Application and Injection Attacks PracticeA security analyst notices that the web application returns different response times when a valid username is submitted versus an invalid one during login. Which type of vulnerability is likely being exploited?
Explanation: Time-based SQL injection involves injecting SQL code that causes the database to pause if a condition is true, allowing an attacker to infer information based on response times. The observed difference in response times for valid vs. invalid usernames is characteristic of this technique.
Which of the following tools is commonly used to automate the detection and exploitation of SQL injection vulnerabilities?
Explanation: SQLMap is a widely used open-source tool that automates the process of detecting and exploiting SQL injection flaws in web applications.
A penetration tester intercepts the following request using Burp Suite: POST /change_password HTTP/1.1 Host: example.com Cookie: sessionid=abc123; SameSite=Lax Content-Type: application/x-www-form-urlencoded new_password=Hacker123 The tester successfully crafts a CSRF attack by embedding a hidden form in a malicious page. Which mitigation is most likely missing?
Explanation: The presence of a SameSite cookie set to Lax does not prevent CSRF for state-changing requests like password change if the attack uses a GET or POST from a top-level navigation. However, the primary missing mitigation is a CSRF token, which is a unique unpredictable value tied to the session and validated by the server.
A web application allows users to upload profile pictures. An attacker uploads a file named "profile.php" containing malicious PHP code. When the attacker visits the uploaded file's URL, the code executes. Which vulnerability is being exploited?
Explanation: The application fails to validate the file type or restrict execution, allowing a malicious PHP file to be uploaded and executed on the server, which is a classic file upload vulnerability leading to remote code execution.
An analyst observes the following log entry on a web server: GET /../../etc/passwd HTTP/1.1 200. Which type of attack is indicated?
Explanation: The log shows a request attempting to traverse directories using '../' to access a sensitive system file (/etc/passwd), which is directory traversal.
