732. Frage
A penetration tester evaluates a company's susceptibility to advanced social engineering attacks targeting its executive team. Using detailed knowledge of recent financial audits and ongoing projects, the tester crafts a highly credible pretext to deceive executives into revealing their network credentials. What is the most effective social engineering technique the tester should employ to obtain the necessary credentials without raising suspicion?
Antwort: A
Begründung:
Spear-phishing leverages highly specific, contextual information to appear legitimate and relevant to the target. By referencing real financial audits and ongoing projects, the attacker builds credibility and trust, making executives far more likely to disclose credentials without suspecting deception.
733. Frage
In the crisp mountain air of Denver, Colorado, ethical hacker Lila Chen investigates the security framework of MedVault, a US-based healthcare platform used by regional clinics to manage patient data. During her assessment, Lila manipulates session parameters while navigating the patient portal's dashboard. Her tests reveal a critical flaw: the system allows users to access sensitive medical records not associated with their own account, enabling unauthorized changes to private health data. Upon deeper inspection, Lila determines that the issue stems from the application allowing users to perform actions beyond their assigned roles rather than failures in encryption, unsafe object handling, or server configuration.
Which OWASP Top 10 2021 vulnerability is Lila most likely exploiting in MedVault's web application?
Antwort: C
Begründung:
Broken Access Control is the correct choice because the scenario describes a user being able to access and modify resources that should be restricted to other users or roles. In CEH-aligned web testing, access control flaws occur when an application fails to enforce authorization checks consistently on the server side.
Manipulating session parameters and then retrieving "sensitive medical records not associated with their own account" is a classic indicator of an authorization bypass, often seen as insecure direct object references, parameter tampering, or horizontal and vertical privilege escalation. Horizontal escalation is when one user accesses another user's data at the same privilege level, while vertical escalation is when a user performs actions reserved for higher-privileged roles. The prompt explicitly states users can perform actions beyond assigned roles, which is the definition of broken authorization enforcement.
The other options do not align with the described root cause. Cryptographic Failures focuses on weak or missing encryption and does not explain why authenticated users can reach unauthorized records. Insecure Deserialization involves unsafe deserialization leading to remote code execution or data tampering via serialized objects, which is not indicated here. Security Misconfiguration is broader and can contribute to exposure, but the scenario emphasizes role and resource permission bypass rather than mis-set server headers, default accounts, or exposed admin interfaces.
Mitigation in CEH best practices includes enforcing server-side authorization on every request, using deny-by- default policies, validating that the authenticated user is allowed to access the specific record identifier, implementing robust role-based access control, logging access denials, and adding automated tests to prevent IDOR and privilege escalation regressions.
734. Frage
A healthcare analytics firm in Denver, Colorado hosts several internal applications on an IIS web server.
During an authorized security assessment, a tester evaluates a lesser-used endpoint designed for administrative operations. By sending crafted HTTP requests directly to this endpoint, the tester is able to invoke server-side management functions without interacting with the standard login workflow presented by the primary user interface.
Further review indicates that certain restricted operations can be executed when accessed through alternate request paths, suggesting inconsistent enforcement of access controls within the application.
Which IIS vulnerability is most accurately demonstrated in this scenario?
Antwort: D
Begründung:
The correct answer is D. Authentication Bypass Vulnerability.
The tester is able to invoke restricted server-side administrative functions by directly sending crafted HTTP requests to an alternate endpoint, without going through the normal login workflow. This indicates that authentication checks are inconsistently enforced and can be bypassed through an alternate request path.
CEH IIS material lists IIS as a frequent target and identifies IIS-related attack categories such as privilege command execution, buffer overflows, source disclosures, and directory traversal weaknesses . CEH web application material also explains that authentication mechanisms can be attacked to bypass authentication or steal information, and that web attacks may use URL, POST data, query strings, cookies, parameters, and HTTP headers to access restricted functions .
Option A. File and Directory Permissions Vulnerability is incorrect because the scenario does not focus on NTFS or web directory permissions.
Option B. CRLF Cross-Site Scripting Vulnerability is incorrect because there is no carriage-return/line-feed injection or script execution described.
Option C. Trust Boundary Violation Vulnerability is related to improper crossing of security boundaries, but the direct and most accurate issue is bypassing authentication to invoke restricted functions.
Option D. Authentication Bypass Vulnerability is correct because the tester accesses administrative operations without completing the required authentication workflow.
Therefore, the best answer is D. Authentication Bypass Vulnerability.
735. Frage
During a covert red team engagement, a penetration tester is tasked with identifying live hosts in a target organization's internal subnet (10.0.0.0/24) without triggering intrusion detection systems (IDS). To remain undetected, the tester opts to use the command nmap -sn -PE 10.0.0.0/24, which results in several " Host is up
" responses, even though the organization's IDS is tuned to detect high-volume scans. After the engagement, the client reviews the logs and is surprised that the scan was not flagged. What allowed the scan to complete without triggering alerts?
Antwort: A
Begründung:
CEH v13 explains that IDS systems are often tuned to detect active scanning behavior, especially port scans and TCP/UDP probing that generate recognizable signatures. The command nmap -sn -PE performs a pure ICMP Echo Request ping sweep without sending any TCP SYN, UDP probes, or other packets normally associated with port enumeration. Since this mode disables port scanning entirely, it produces minimal traffic that resembles legitimate network behavior. CEH emphasizes that many networks allow ICMP Echo traffic internally for diagnostics, so such pings may not be treated as suspicious unless rate thresholds are exceeded.
Because the tester avoided SYN packets, ACK probes, and UDP scans, the IDS saw no malicious pattern or connection attempts. The effectiveness of this technique is highlighted in CEH under passive and stealth reconnaissance, where minimal interaction is used to avoid detection. Thus, the scan succeeded because it relied solely on ICMP host discovery, not port scanning.
736. Frage
Which of these is capable of searching for and locating rogue access points?
Antwort: A
Begründung:
A Wireless Intrusion Prevention System (WIPS) is a network device that monitors the radio spectrum for the presence of unauthorized access points (intrusion detection), and can automatically take countermeasures (intrusion prevention).
