PT0-003 Exam Dumps : CompTIA PenTest+ Exam

To perform credentialed scans on an Active Directory (AD) server, the scanner requires high-level access to retrieve system configuration, patch levels, and user rights. A Domain Administrator account ensures full visibility into domain resources and permissions, which is essential for a complete vulnerability assessment.

From the CompTIA PenTest+ PT0-003 Objectives – Domain 2.0: Information Gathering and Vulnerability Identification:

“Credentialed scans require administrative-level access on target systems to provide detailed insights into software versions, missing patches, and security settings.”

IAM (Identity and Access Management) credentials are used to control and manage access to cloud services and resources. When a penetration tester obtains IAM credentials, especially those with administrative privileges, they can perform high-level operations such as provisioning services, modifying configurations, or accessing sensitive data across the cloud environment.

SSH keys would only grant access to a specific instance, not cloud-wide services.

Cloud storage credentials are limited to storage access, not administrative capabilities.

Temporary security credentials (STS) provide limited-time access and are not typically used for broad administrative tasks.

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.
