6 Free CEH Web Application Hacking Practice Questions with Answers

Each question below includes 4 answer options, the correct answer, and a detailed explanation. These are real questions from the FlashGenius CEH 312-50 v13 question bank for the Web Application Hacking domain (16% of the exam).

Sample Question 1 — Hacking Web Servers

While performing a penetration test on a web server, you discover that the server is using an outdated version of Apache. Which tool would be most appropriate to identify known vulnerabilities associated with this version?

  1. A. Nessus (Correct answer)
  2. B. Wireshark
  3. C. Burp Suite
  4. D. Nikto

Correct answer: A

Explanation: Nessus is a widely used vulnerability scanner that can identify known vulnerabilities in software, including web servers. It has a comprehensive database of vulnerabilities, making it suitable for this task. Wireshark is a network protocol analyzer, Burp Suite is primarily used for web application testing, and Nikto is a web server scanner but is less comprehensive than Nessus for this purpose.

Sample Question 2 — Hacking Web Servers

During a security assessment, you need to identify default files and scripts on a web server that might pose security risks. Which tool would you choose to automate this task efficiently?

  1. A. Metasploit
  2. B. Nikto (Correct answer)
  3. C. Nmap
  4. D. John the Ripper

Correct answer: B

Explanation: Nikto is designed to scan web servers for potentially dangerous files and scripts, outdated server software, and other security issues. Metasploit is used for exploitation, Nmap is a network scanner, and John the Ripper is a password cracker.

Sample Question 3 — Hacking Web Servers

You are tasked with testing the security of a web server that may have directory traversal vulnerabilities. What is the best approach to verify this vulnerability?

  1. A. Attempt to upload a malicious script and execute it
  2. B. Use a web proxy to modify requests and attempt to access sensitive files using '../' sequences (Correct answer)
  3. C. Use a SQL injection tool to test database security
  4. D. Run a denial-of-service attack to check server resilience

Correct answer: B

Explanation: Using a web proxy to modify requests allows you to test for directory traversal by manually inserting directory traversal sequences (e.g., '../') to access sensitive files. This is a direct way to check for such vulnerabilities. Uploading scripts or performing DoS attacks are not appropriate for this specific test, and SQL injection testing is unrelated.

Sample Question 4 — Hacking Web Servers

While reviewing a web server, you find that sensitive information is being disclosed through directory listings. What is the best immediate action to mitigate this vulnerability?

  1. A. Configure firewall rules to block traffic
  2. B. Disable directory listing on the web server's configuration (Correct answer)
  3. C. Implement SSL/TLS to encrypt data in transit
  4. D. Update the web server software to the latest version

Correct answer: B

Explanation: Disabling directory listing in the web server configuration is the correct action to prevent sensitive information disclosure through directory listings. Firewall rules and SSL/TLS are not directly related to this specific issue, and updating software does not address directory listing directly.

Sample Question 5 — Hacking Web Servers

You are conducting a penetration test on a web server and find that it is vulnerable to the Heartbleed bug. Which of the following actions should you recommend to rectify this issue?

  1. A. Disable SSL altogether
  2. B. Update OpenSSL to a version patched against Heartbleed (Correct answer)
  3. C. Restrict access to the server using IP whitelisting
  4. D. Use a web application firewall to block exploitation attempts

Correct answer: B

Explanation: Updating OpenSSL to a version that is patched against Heartbleed is the correct way to address the vulnerability. Disabling SSL would compromise data security, IP whitelisting doesn't address the root cause, and a web application firewall is not a permanent solution for this vulnerability.

Sample Question 6 — Hacking Web Servers

During a web server audit, you need to test for vulnerabilities in server configuration and installed modules. Which tool would provide the most detailed report?

  1. A. Wireshark
  2. B. Nikto
  3. C. Nessus (Correct answer)
  4. D. Burp Suite

Correct answer: C

Explanation: Nessus provides comprehensive vulnerability scanning, including testing server configurations and installed modules. Nikto also scans servers, but Nessus offers more detailed reporting. Wireshark is for packet analysis, and Burp Suite focuses on web applications specifically.

How to Study CEH Web Application Hacking

Combine these CEH Web Application Hacking practice questions with hands-on labs in a Kali Linux VM and on platforms like TryHackMe, HackTheBox, or the official CEH iLabs. The 312-50 v13 exam emphasizes practical attacker tradecraft, so always test commands and tools in a sandboxed environment — that hands-on muscle memory is what separates passing and failing scores.
