Overview of this book

Metasploit® software helps security and IT professionals identify security issues, verify vulnerability mitigations, and manage expert-driven security assessments. Capabilities include smart exploitation, password auditing, web application scanning, and social engineering. Teams can collaborate in Metasploit and present their findings in consolidated reports. The goal of the software is to provide a clear understanding of the critical vulnerabilities in any environment and to manage those risks.Metasploit Penetration Testing Cookbook targets both professionals and beginners to the framework. The chapters of the book are logically arranged with an increasing level of complexity and cover Metasploit aspects ranging from pre-exploitation to the post-exploitation phase thoroughly. The recipe structure of the book provides a good mix of both theoretical understanding and practical implementation. This book will help readers in thinking from a hacker's perspective to dig out the flaws in target networks and also to leverage the powers of Metasploit to compromise them. It will take your penetration skills to the next level.The book starts with the basics such as gathering information about your target and gradually covers advanced topics like building your own framework scripts and modules. The book goes deep into operating systems-based penetration testing techniques and moves ahead with client-based exploitation methodologies. In the post- exploitation phase, it covers meterpreter, antivirus bypass, ruby wonders, exploit building, porting exploits to framework, and third party tools like armitage, and SET. Metasploit Penetration Testing Cookbook is the required guide to penetration testing and exploitation.

Windows 7/Server 2008 R2 SMB client infinite loop


There are very few exploits available for Windows 7 and Windows Server 2008. The SMB client infinite loop is one such vulnerability that causes a system crash. This vulnerability will not provide any session or shell connectivity, but it is worth discussing. We will deal with the DLL injection flaw in Windows 7 in the Understanding the Windows DLL injection flaws recipe.

The SMB client in the kernel in Microsoft Windows Server 2008 R2 and Windows 7 allows remote SMB servers and man-in-the-middle attackers to cause a denial of service (infinite loop and system hang) via SMBv1 or SMBv2 response packet. The packet contains an incorrect length value in a NetBIOS header or an additional length field at the end of this response packet. This incorrect header value is the main reason for the vulnerability.

Getting ready

Metasploit contains an auxiliary module auxiliary/dos/windows/smb/ms10_006_negotiate_response_loop which can be used to exploit the...
