Library of expert validated exploits for safe and effective pen tests
Exploit development can be an advanced penetration testing skill that takes time to master. Additionally, when on a job, pen testers often don’t have the resources to create a new exploit. Many resort to searching for and using pre-written exploits that have not been tested and must go through the timely effort of quality assurance testing in order to ensure they are secure and effective.
Core Impact users can save time by finding all the up-to-date exploits they need in one place. We provide a robust library of exploits designed to enable pen testers to safely and efficiently conduct successful penetration tests. Whether written by our own internal team or by a third party like ExCraft, you can trust they have been thoroughly tested and validated by our experts.
The universe of vulnerabilities is huge and not all of them represent the same risk for the customers. Vulnerabilities do not all have the same level of criticality. Some may be easily exploitable by a low-level user, while others may not be exploitable at all. To increase the efficiency of the attacks and the quality of the exploits provided, the Core Impact team has developed selection criteria to prioritize its analysis and implementation. We determine which exploits warrant creation based on the following questions:
What are the most critical attacks from the attacker’s perspective?
What new vulnerabilities are more likely to be exploited in real attacks?
What exploits are the most valuable for Core Impact?
Once an exploit is approved, its priority order considers the following variables:
Vulnerability Properties: CVE, disclosure date, access mechanism and privileges needed.
Target Environment Setup: OS, application prevalence, version and special configurations needed.
Value Provided to Core Impact: Customer request, usage in multiple attacks, allows the installation of an agent, etc.
Technical Cost vs. Benefit: An analysis weighing the resources needed to build an exploit with the internal and external knowledge gained in its creation.
Each one of these variables has a different weight and provides a ranking of the potential exploits to be developed. Following those criteria, the top of the list would contain, for example, a vulnerability on Windows (most popular OS) that can be exploited remotely, without authentication and that provides super user privileges.
Correspondingly, a vulnerability on an application that is rarely installed, needs special configurations, and requires User Interaction, would be at the bottom.

This update improves reliability for 8.x versions.
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Jungo WinDriver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the processing of IOCTL 0x953824a7 by the windrvr12xx kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in an out-of-bounds write condition. An attacker can leverage this vulnerability to execute arbitrary code under the context of kernel.
Nitro Pro PDF Reader Javascript API Remote Code Execution Exploit
This module exploits an unsafe Javascript API implemented in Nitro and Nitro Pro PDF Reader. The saveAs() Javascript API function allows for writing arbitrary files to the file system. Additionally, the launchURL() function allows an attacker to execute local files on the file system and bypass the security dialog.
This module exploits a vulnerability in Microsoft Office Word. The flaw is related in how Microsoft Word handles OleLink objects. It is possible to open a RTF file and execute arbitrary code in vulnerables installations of Microsoft Office Word.
This vulnerability was originally seen being exploited in the wild starting in October 2016.
Apple QuickTime Java toQTPointer() code execution exploit update
This module exploits a memory corruption vulnerability in the Java QuickTime for Java (QtJava.dll) browser plug-in. The module runs a malicious web server on the CORE IMPACT Console and waits for an unsuspecting user(s) to connect to it with a Java-enabled browser using the vulnerable plug-in. When a user connects to the site they trigger the exploit and the module attempts to install an agent on their computer. This update adds support for Safari browser in Mac OS X (i386) and adds Opera support in Windows.
