Privilege Escalation Techniques

Overview of this book

Privilege Escalation Techniques is a detailed guide to privilege escalation techniques and tools for both Windows and Linux systems. This is a one-of-a-kind resource that will deepen your understanding of both platforms and provide detailed, easy-to-follow instructions for your first foray into privilege escalation. The book uses virtual environments that you can download to test and run tools and techniques. After a refresher on gaining access and surveying systems, each chapter will feature an exploitation challenge in the form of pre-built virtual machines (VMs). As you progress, you will learn how to enumerate and exploit a target Linux or Windows system. You’ll then get a demonstration on how you can escalate your privileges to the highest level. By the end of this book, you will have gained all the knowledge and skills you need to be able to perform local kernel exploits, escalate privileges through vulnerabilities in services, maintain persistence, and enumerate information from the target such as passwords and password hashes.

Chapter 8: Exploiting Services

Now that you have a good grasp of the common privilege escalation attack vectors on Windows, we can take a deeper look at Windows services and begin exploring the privilege escalation techniques that leverage vulnerabilities and misconfigurations in services in order to elevate our privileges on the target system. The objective of this chapter is to identify and exploit vulnerabilities and misconfigurations in common Windows services.

We will explore the process of identifying and exploiting unquoted service paths and weak service permissions, and we will then take a look at how to exploit the Windows secondary logon in order to elevate our privileges. We will also take an in-depth look at the process of identifying and hijacking missing Dynamic Link Libraries (DLLs).

In this chapter, we're going to cover the following main topics:

  • Exploiting services and misconfigurations
  • Exploiting unquoted service paths
  • Exploiting secondary...
