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 Java plugin for Internet Explorer (jp2iexp.dll) is affected by a stack-based buffer overflow when processing the docBase parameter of a Java applet. This can be exploited to execute arbitrary code with the privileges of the current user by enticing the victim to visit a malicious web page.
This update adds DEP bypassing capability to the exploit, and adds support for Windows 7, Windows Server 2008, and Internet Explorer 8.
This module exploits a buffer overflow vulnerability in Lotus Notes 8.5 when parsing a malformed, specially crafted WK3 (SpreadSheet Lotus 1-2-3 Document) file.
QQPlayer contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error in QQPlayer when handling .ASX files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .ASX file.
Microsoft Windows LNK Shortcut Automatic File Execution Exploit
Microsoft Windows is prone to a vulnerability that may allow a file to automatically run because the software fails to handle 'LNK' files properly. Specifically, the issue occurs when loading the icon of a shortcut file. A specially crafted 'LNK' file can cause Windows to automatically execute code that is specified by the shortcut file. This vulnerability is currently being exploited in the wild.
An integer overflow error exists in the processing of MP4 files. This can be exploited to cause a heap-based buffer overflow via e.g. an MP4 file containing a specially crafted "ctts" box.
Microsoft Windows helpctr Invalid URL Processing Exploit
This module exploits a vulnerability caused due to an error in the MPC::HTML::UrlUnescapeW() function in helpctr.exe when escaping URLs.
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 module exploits a vulnerability in Adobe Reader when parsing .PDF files. The vulnerability is caused due to a boundary error in authplay.dll when handling crafted malicious Flash (.SWF) file or by embedding a malicious Flash application in a .PDF file.
A use-after-free vulnerability in WebKit/Apple Safari (in versions prior to 4.0.5) allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via HTML elements with right-to-left (RTL) text directionality.
FeedDemon OPML Outline Tag Buffer Overflow Exploit
FeedDemon is prone to a remote buffer-overflow vulnerability because the application fails to perform adequate boundary checks when opening .OPML files.
Yahoo Player contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error in Yahoo Player when handling .YPL files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .YPL file.
Novell iPrint Client Date Time Parameter Buffer Overflow Exploit
This module exploits a vulnerability in the ienipp.ocx control included in the Novell iPrint Client application. The exploit is triggered when the Date Time parameter processes a long string argument resulting in a stack-based buffer overflow.
This module exploits a stack based buffer overflow vulnerability in Sun Java SE in JDK and JRE when the HsbParser.getSoundBank function in jsound.dll handles a specially crafted .JAR file.
Euphonics Audio Player PLS Buffer Overflow Exploit
Euphonics Audio Player contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error when handling .PLS files.
The Ultra Office Control ActiveX control (OfficeCtrl.ocx) is vulnerable to a stack-based buffer overflow. By persuading a victim to visit a specially-crafted Web page that passes an overly long string to the HttpUpload() method, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the current user or cause the victim's browser to crash.
A security vulnerability with the way XnView processes TAAC files may allow a remote unprivileged user who provides a TAAC document that is opened or previewed by a local user to execute arbitrary commands on the system with the privileges of the user running XnView. This can be exploited to cause a buffer overflow when a specially crafted file is opened or previewed in XnView.
The specific flaw exists within the parsing of a pm3 project file. A heap-based buffer overflow vulnerability exists in a call to memcpy. An attacker can leverage this vulnerability to execute arbitrary code in the context of the process.
Microsoft Visual Basic VBP File Processing Buffer Overflow Exploit
This module exploits a vulnerability in Visual Basic 6 .vbp files. The vulnerability is caused due to boundary error in VB6.EXE within the processing of VBP archives. This can be exploited to cause a stack-based buffer overflow when a specially crafted file is opened.
This module exploits a integer overflow vulnerability in the xpdf and libpoppler software included in most linux distributions. The vulnerability is caused by a integer overflow in the predictor calculation, which causes a buffer overflow in the stack of the StreamPredictor::getNextLine() function. The exploit is triggered when an unsuspecting user opens a specially crafted file distributed via an email.
This module exploits a vulnerability in the kwedit.dll control included in the EnjoySAP application. The exploit is triggered when the PrepareToPostHTML() method processes a long string argument resulting in a stack-based buffer overflow. This module runs a malicious web site on the CORE IMPACT Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.
