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 vulnerability is caused due to a boundary error when parsing format strings containing a floating point specifier in the util.printf() JavaScript function.
This update improves exploit reliability and fixes a cookie handling bug.
Fuji Electric V-Server VPR File Parsing Buffer Overflow Exploit (CVE-2018-10637)
The specific flaw exists within the processing of VPR files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a buffer.
This module exploits a vulnerability in the InstallShield Update Service ActiveX control (isusweb.dll) in MacroVision FLEXnet Connect and InstallShield 2008.
Multiple stack-based buffer overflow vulnerabilities have been identified in which the application does not verify string size before copying to memory, the attacker may then be able to crash the application or run arbitrary code.
The specific flaw exists within the processing of DVP files. The process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
Apple QuickTime Java toQTPointer() code execution exploit
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.
Apple QuickTime QTVR QTVRStringAtom Buffer Overflow Exploit
The vulnerability exists within the QuickTimeVR.qtx component when processing a QTVRStringAtom having an overly large "stringLength" parameter. This can be exploited to cause a based buffer overflow and execute arbitrary code under the context of the user running the application.
The specific flaw exists within the Connect method in webeye.ocx module.The control does not check the length of an attacker-supplied string in the Connect method before copying it into a fixed length buffer on the stack. This allows an attacker to execute arbitrary code in the context of the browser process.
Microsoft MDAC RDS.Dataspace ActiveX Control Exploit
The RDS.Dataspace ActiveX control includes a method that can create an instance of an ActiveX control that exists on the system. The ActiveX objects created in this manner will bypass the ActiveX security model. In particular, the "safe for scripting" and killbit options are ignored. Note that in default configurations of Internet Explorer, the RDS.Dataspace ActiveX control cannot be loaded in the Internet Zone.
The vulnerability is caused due to boundary errors in libpurple.dll within the processing of MSNSLP messages. This can be exploited to cause an arbitrary write without user interaction.
This module updates the MSN library, because of minor changes in the handling of the HTTP encapsulation of the MSN protocol within the Microsoft MSN server.
The vulnerability is caused due to boundary errors in libpurple.dll within the processing of MSNSLP messages. This can be exploited to cause a stack-based buffer overflow without user interaction.
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.
The vulnerability is caused due to a boundary error in MoviePlay when handling .LST files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .LST file.
This module runs a malicious web server on the CORE IMPACT Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
This module exploits a vulnerability in the WBEMSingleView.ocx control included in the WMI Tools ActiveX application. The exploit is triggered when the OpenURL() method processes a long string argument resulting in a stack-based buffer overflow.
Adobe Flash Player SWF File Uninitialized Memory Exploit
A vulnerability has been identified in Adobe Flash Player, which could be exploited by attackers to compromise a vulnerable system. This issue is caused by an uninitialized memory access triggered by a specially crafted .SWF file, which could be exploited by attackers to execute arbitrary code.
This vulnerability has been found exploited in-the-wild during March 2011.
This module exploits a stack-based buffer overflow in the MSCOMCTL.OCX control by sending a specially crafted .RTF file.

Microsoft Word MSCOMCTL TabStrip Control Use-after-free Exploit(MS12-060) Update
A Memory Corruption in Microsoft Word is caused due to an error within the TabStrip ActiveX control (MSCOMCTL.OCX) object, embedded in a RTF crafted file.
Microsoft Internet Explorer CFlatMarkupPointer Use-After-Free (MS13-059)
Use after free in Internet Explorer when an invalid reference to CFlatMarkupPointer is used. Successful control of the freed memory may leverage arbitrary code execution under the context of the user.
Oracle WebCenter Content is prone to a Remote File Execution vulnerability within the CheckOutAndOpen.dll ActiveX when using openWebdav method. By specifying a constructed path an attacker can force the contents of the file to be passed to ShellExecuteExW, thus being able to execute arbitrary files. The payload is embedded on a VBS file which is automatically executed when a HTA file is requested through Webdav.
