20+ practice questions focused on Vulnerability Analysis and System Hacking — 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 Vulnerability Analysis and System Hacking PracticeAn ethical hacker is assessing a Linux web server running Apache. The server is suspected to have a remote file inclusion (RFI) vulnerability. Which testing approach is most appropriate to confirm the vulnerability without causing damage?
Explanation: This approach uses a local file inclusion (LFI) parameter to safely test for file inclusion vulnerabilities without causing damage. By attempting to include /etc/passwd, the tester can verify if the server processes user-supplied input to include local files. While this directly confirms LFI, a successful LFI often indicates underlying input validation flaws that could also lead to RFI, making it a common and non-destructive first step to assess for file inclusion vulnerabilities in general, including the potential for RFI.
Which TWO of the following are valid techniques for password cracking?
Explanation: A brute-force attack is a valid password cracking technique that systematically tries every possible combination of characters until the correct password is found. A rainbow table attack is also a valid password cracking technique that uses pre-computed hashes to reverse cryptographic hash functions, often for passwords. Both directly aim to discover the plaintext password.
Based on the Nmap scan output, which service is most likely vulnerable to remote code execution?
Explanation: Apache Tomcat 8.5.5 is known to be vulnerable to remote code execution (RCE) via the Ghostcat vulnerability (CVE-2020-1938), which exploits the AJP connector on port 8009. This allows an attacker to read or execute arbitrary files on the server, making it the most likely candidate for RCE among the listed services.
Based on the exhibit, which service should be targeted first to gain initial access with the highest chance of success?
Explanation: The explanation incorrectly states that CVE-2016-6662 is a 'critical remote code execution vulnerability... without requiring authentication' for initial access. CVE-2016-6662 is a local privilege escalation vulnerability in MySQL/MariaDB's mysqld_safe script, requiring local file write access to exploit, not remote initial access. Therefore, it does not justify option D as the 'highest chance of success' for initial remote access. The question also cannot be properly evaluated without the 'exhibit' mentioned in the stem, which would provide crucial context about the services and their versions.
A security auditor reviews password hashes for three users: admin uses SHA-512 (hash prefix $6$...), root uses SHA-512 (hash prefix $6$...), and user uses MD5 (hash prefix $1$...). Which user has the weakest password hash?
Explanation: The user hash prefix $1$ indicates MD5, which is cryptographically broken and much faster to attack than SHA-512 ($6$). The admin and root hashes use SHA-512, which is significantly stronger. Therefore, user has the weakest password hash.

Start with 10 questions to gauge your current understanding of Vulnerability Analysis and System Hacking. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Vulnerability Analysis and System Hacking questions on the CEH frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Vulnerability Analysis and System Hacking is tested as part of the Certified Ethical Hacker CEH blueprint. Practicing with targeted Vulnerability Analysis and System Hacking questions ensures you can handle any format or difficulty that appears.
