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.

The sun.plugin2.applet.Applet2ClassLoader class of Oracle Java does not properly validate if the URL of a Java class file matches the "codebase" parameter while loading applets. This vulnerability allows an applet to execute arbitrary code outside the sandbox without restrictions, which can be exploited to install an agent on the target machine.
Microsoft Internet Explorer Exec Function Use After Free Exploit
A use-after-free vulnerability in the CMshtmlEd::Exec function in mshtml.dll in Microsoft Internet Explorer 6 through 9 allows remote attackers to execute arbitrary code via a crafted web site, as exploited in the wild in September 2012. This module runs a web server waiting for vulnerable clients to connect to it. When the client connects, it will try to install an agent by exploiting this vulnerability. This is an early release module. This is not the final version of this module.
HP LoadRunner lrFileIOService ActiveX Control WriteFileBinary Exploit
The specific flaw exists within the lrFileIOService ActiveX control. The control exposes the WriteFileBinary method which accepts a parameter named data that it uses as a valid pointer. By specifying invalid values an attacker can force the application to jump to a controlled location in memory. This can be exploited to execute remote code under the context of the user running the web browser.
The vulnerability is caused due to a boundary error within Mini HTTPD when processing HTTP GET Request. This can be exploited to cause a stack-based buffer overflow via an overly long, specially-crafted argument passed to the affected command. Arbitrary code can be directly executed by overwriting a return address.

Adrenalin Player WAX Buffer Overflow Exploit
This module exploits a vulnerability in Adrenalin Player .WAX files. The vulnerability is caused due to lack of boundary checks in exporting a WAX file witch causes an Buffer Overflow of the stack and a SEH attack is possible due to a vulnerable DLL included in the software.

PHP-CGI Argument Injection Exploit
This module exploits an argument injection vulnerability in PHP up to version 5.3.12 and 5.4.2 when running as a standalone CGI processor and takes advantage of the -d flag to achieve remote code execution. WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations. Since this module is not the final version it may contain bugs or have limited functionality and may not have complete or accurate documentation.
Sketchup MAC Pict Material Palette Stack Corruption Exploit
Sketchup fails to validate the input when parsing an embedded MAC Pict texture, leading to an arbitrary stack offset overwrite and finally to an arbitrary code execution.
This module abuses a vulnerability in phpMyAdmin 3.5.x before 3.5.8 and 4.x before 4.0.0-rc3 that allows remote authenticated users to execute arbitrary code via a /e\x00 sequence, which is not properly handled before making a preg_replace function call within the "Replace table prefix" feature.
Microsoft Windows Win32k Improper Message Handling Vulnerability Exploit (MS13-005)
An elevation of privilege vulnerability exists when the Windows kernel improperly handles window broadcast messages. An attacker who successfully exploited this vulnerability could take complete control of an affected system.
The vulnerability is caused due to a boundary error in PrintControl.dll ActiveX control when processing the ServerResourceVersion property and can be exploited via an overly long string.
An error in the way the bytecode verifier of Java validates field access instructions when preparing to JIT-compile a method can be abused to cause a type confusion vulnerability. This flaw allows an unprivileged Java applet to escape the sandbox and execute arbitrary code on the target machine with the privileges of the current user.
A Stack-based buffer overflow in VideoLAN VLC media player allows remote attackers to execute arbitrary code via a crafted MMS:// stream. This version fix a bug with source ip calculation.
Winamp Computer Name Handling Buffer Overflow Exploit
This module exploits a vulnerability in Winamp 5.12 WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations. Since this module is not the final version it may contain bugs or have limited functionality and may not have complete or accurate documentation. This update can be downloaded and installed by selecting 'Modules' -> 'Update modules' from IMPACT's main menu. A workspace must be opened for the operation to succeed.
This module exploits an unchecked buffer in the Client Service for NetWare on Microsoft Windows, and installs an agent (MS05-046). This update adds support for Windows XP.
An internal memory buffer may be overrun while handling long "USER" command. This condition may be exploited by attackers to ultimately execute instructions with the privileges of the FreeFTPdService.exe process.
MSRPC Server Service Remote Buffer Overflow Exploit (MS08-067) Update 6
This module exploits a vulnerability in the Microsoft Windows Server service by sending a specially crafted RPC request. This update adds support for Windows XP sp0 and sp1.
