19+ 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 PracticeA penetration tester discovers that a target Windows system has port 445 open and responds to SMB requests. Which tool should the tester use to enumerate users, shares, and OS information from this system?
Explanation: enum4linux is a tool specifically designed to enumerate information from Windows and Samba systems via SMB. It leverages the SMB protocol to extract users, shares, OS details, and other system information from a target with port 445 open, making it the correct choice for this scenario.
An 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: Option A is correct because it uses a local file inclusion (LFI) parameter to test for file inclusion without causing damage. By attempting to include /etc/passwd, the tester can verify if the server processes user-supplied input to include files, which is a direct indicator of an RFI vulnerability if the server returns the file contents. This approach is safe and non-destructive, as it only reads a standard system file.
During a penetration test, a tester gains access to a Linux system and needs to escalate privileges. The tester finds that the user has sudo privileges to run /usr/bin/less as root without a password. Which technique should the tester use to escalate privileges?
Explanation: Option B is correct because when a user has sudo privileges to run /usr/bin/less as root without a password, the tester can leverage the fact that less can execute shell commands from within its interface. By running 'sudo /usr/bin/less' and then typing '!/bin/bash', the tester spawns a root shell, effectively escalating privileges to root.
A security analyst runs a vulnerability scan and finds that a server is vulnerable to CVE-2021-44228 (Log4j). Which of the following is the best immediate remediation step?
Explanation: Option A is correct because CVE-2021-44228 (Log4Shell) is a remote code execution vulnerability in Apache Log4j versions 2.0 through 2.14.1, triggered by JNDI lookups in log messages. Updating to Log4j 2.17.1 or later fully patches the flaw by disabling JNDI lookups by default and fixing the LDAP deserialization vector. This is the vendor-recommended immediate remediation step as it addresses the root cause without relying on workarounds.
An ethical hacker is testing a web application that uses cookies for session management. The tester notices that the session cookie does not have the HttpOnly or Secure flags set. Which attack is most likely to succeed due to this misconfiguration?
Explanation: Option C is correct because the absence of the HttpOnly flag allows JavaScript to access the session cookie via `document.cookie`. An attacker can exploit a cross-site scripting (XSS) vulnerability to steal the cookie and perform session hijacking. The missing Secure flag further exposes the cookie to interception over unencrypted HTTP connections, making the attack easier to execute.
