As part of a security audit, a penetration tester finds an internal application that accepts unexpected user inputs, leading to the execution of arbitrary commands. Which of the following techniques would the penetration tester most likely use to access the sensitive data?

1. A. Logic bomb
2. B. SQL injection
3. C. Brute-force attack
4. D. Cross-site scripting

Correct Answer: B
SQL injection (SQLi) is a technique that allows attackers to manipulate SQL queries to execute arbitrary commands on a database. It is one of the most common and effective methods for accessing sensitive data in internal applications that accept unexpected user inputs. Here??s why option B is the most likely technique:
✑ Arbitrary Command Execution: The question specifies that the internal application accepts unexpected user inputs leading to arbitrary command execution. SQL injection fits this description as it exploits vulnerabilities in the application's input handling to execute unintended SQL commands on the database.
✑ Data Access: SQL injection can be used to extract sensitive data from the database, modify or delete records, and perform administrative operations on the database server. This makes it a powerful technique for accessing sensitive information.
✑ Common Vulnerability: SQL injection is a well-known and frequently exploited vulnerability in web applications, making it a likely technique that a penetration tester would use to exploit input handling issues in an internal application.
References from Pentest:
✑ Luke HTB: This write-up demonstrates how SQL injection was used to exploit an internal application and access sensitive data. It highlights the process of identifying and leveraging SQL injection vulnerabilities to achieve data extraction.
✑ Writeup HTB: Describes how SQL injection was utilized to gain access to user credentials and further exploit the application. This example aligns with the scenario of using SQL injection to execute arbitrary commands and access sensitive data.
Conclusion:
Given the nature of the vulnerability described (accepting unexpected user inputs leading to arbitrary command execution), SQL injection is the most appropriate and likely technique that the penetration tester would use to access sensitive data. This method directly targets the input handling mechanism to manipulate SQL queries, making it the best choice.

A penetration tester runs a vulnerability scan that identifies several issues across numerous customer hosts. The executive report outlines the following information:
Server High-severity vulnerabilities
* 1. Development sandbox server 32
* 2. Back office file transfer server 51
* 3. Perimeter network web server 14
* 4. Developer QA server 92
The client is con ble monitoring mode using Aircrack-ng ch of the following hosts should the penetration tester select for additional manual testing?

1. A. Server 1
2. B. Server 2
3. C. Server 3
4. D. Server 4

Correct Answer: C
✑ Client Concern:
✑ Server Analysis:
✑ Pentest References:
By selecting Server 3 (the perimeter network web server) for additional manual testing, the penetration tester addresses the client's primary concern about the availability and security of the consumer-facing production application.

HOTSPOT
A penetration tester is performing reconnaissance for a web application assessment. Upon investigation, the tester reviews the robots.txt file for items of interest.
INSTRUCTIONS
Select the tool the penetration tester should use for further investigation.
Select the two entries in the robots.txt file that the penetration tester should recommend for removal.

Solution:
The tool that the penetration tester should use for further investigation is WPScan. This is because WPScan is a WordPress vulnerability scanner that can detect common WordPress security issues, such as weak passwords, outdated plugins, and misconfigured settings. WPScan can also enumerate WordPress users, themes, and plugins from the robots.txt file.
The two entries in the robots.txt file that the penetration tester should recommend for removal are:
✑ Allow: /admin
✑ Allow: /wp-admin
These entries expose the WordPress admin panel, which can be a target for brute-force attacks, SQL injection, and other exploits. Removing these entries can help prevent unauthorized access to the web application??s backend. Alternatively, the penetration tester can suggest renaming the admin panel to a less obvious name, or adding authentication methods such as two-factor authentication or IP whitelisting.

Does this meet the goal?

1. A. Yes
2. B. No

Correct Answer: A

A penetration tester enumerates a legacy Windows host on the same subnet. The tester needs to select exploit methods that will have the least impact on the host's operating
stability. Which of the following commands should the tester try first?

1. A. responder -I eth0 john responder_output.txt <rdp to target>
2. B. hydra -L administrator -P /path/to/pwlist.txt -t 100 rdp://
3. C. msf > use msf > set msf > set PAYLOAD windows/meterpreter/reverse_tcp msf > run
4. D. python3 ./buffer_overflow_with_shellcode.py 445

Correct Answer: A
Responder is a tool used for capturing and analyzing NetBIOS, LLMNR, and MDNS queries to perform various man-in-the-middle (MITM) attacks. It can be used to capture hashed credentials, which can then be cracked offline. Using Responder has the least impact on the host's operating stability compared to more aggressive methods like buffer overflow attacks or payload injections.

Which of the following components should a penetration tester include in an assessment report?

1. A. User activities
2. B. Customer remediation plan
3. C. Key management
4. D. Attack narrative

Correct Answer: D
An attack narrative provides a detailed account of the steps taken during the penetration test, including the methods used, vulnerabilities exploited, and the outcomes of each attack. This helps stakeholders understand the context and implications of the findings.
