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.

Adobe Flash Player shared ByteArray Use-After-Free Exploit
This module exploits a Use-After-Free vulnerability in Adobe Flash Player. The method ByteArray::clear does not notify the suscriber when frees the memory assigned to a ByteArray object leaving a dangling pointer that can be later dereferenced. This vulnerability allows attackers to execute arbitrary code on vulnerable machines by enticing unsuspecting users to visit a website serving a specially crafted SWF Flash file. This vulnerability was found exploited in the wild in February 2015.
GE Proficy CIMPLICITY gefebt Remote Code Execution
The vulnerable component gefebt allows to execute remote BCL files in shared resources. An attacker can abuse this behaviour to execute a malicious BCL and drop an arbitrary EXE .This can be executed remotely through the WebView server.
This update includes a module that remotely exploits CVE-2015-0235 (a.k.a. GHOST, a heap-based buffer overflow in the GNU C Library's gethostbyname functions) on x86 and x86_64 GNU/Linux systems that run the Exim mail server.
The specific flaw exists within the AnnotateX dll ActiveX control included with the software. An attacker can use an unvalidated object parameter in the Insert() function to execute arbitrary code in the context of the browser.
Microsoft Windows LNK Shortcut Automatic DLL Loading Exploit (MS15-020)
Microsoft Windows is prone to a vulnerability that may allow a DLL file to be automatically loaded 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 the result of an incomplete fix for MS10-046 (CVE-2010-2568). WARNING: This is an early release module. This is not the final version of this module.
A vulnerability in Microsoft's implementation of the Kerberos authentication protocol allows to modify a Kerberos ticket to remotely escalate privileges. This module exploits the vulnerability impersonating a user of the domain's Administrators group to install an agent in the domain controller with System privileges. This update solves issues related to name resolution of the target and to running the exploit with a source agent installed on a Linux host.
Adobe Flash Player casi32 Integer Overflow Exploit
This module exploits an integer overflow in Adobe Flash Player. The specific flaw exists within the implementation of casi32. The issue lies in the failure to properly sanitize a user-supplied length value with a specific array implementation. An attacker can leverage this vulnerability to execute code within the context of the current process.
Adobe Flash Player ByteArray UncompressViaZlibVariant Use-After-Free Exploit
Adobe Flash Player is prone to a use-after-free vulnerability because the ByteArray::UncompressViaZlibVariant method frees an object while leaving a dangling pointer that can be later dereferenced. This vulnerability allows attackers to execute arbitrary code on vulnerable machines by enticing unsuspecting users to visit a website serving a specially crafted SWF Flash file.
POODLE TLS1.x to SSLv3 Downgrading Vulnerability Exploit
This module exploits a vulnerability in Internet Explorer 10/11 by downgrading the encryption from TLS 1.x to SSLv3. After that, part of the encrypted text plain will be decrypted.
The specific flaw exists within the 'factory' object's loadExtensionFactory method. The issue lies in a failure to validate the size of an attacker-supplied input before copying it into a fixed-size buffer on the stack. An attacker can leverage this vulnerability to execute code under the context of the current process.
Adobe Flash Player copyPixelsToByteArray Heap Buffer Overflow Exploit
This module exploits a heap-based buffer overflow in Adobe Flash Player. The bug is triggered by calling BitmapData.copyPixelsToByteArray() with a reference to a ByteArray that has its position property set very large, close to 2^32. This results in an integer overflow in 32-bit arithmetic and allows an attacker to take control of the target machine.
CorelDRAW Graphics Suite X7 Wintab32 DLL Hijacking Exploit
Untrusted search path vulnerability in CorelDRAW X7 17.1.0.572, Corel Photo-Paint X7 17.1.0.572, Corel PaintShop Pro X7 17.0.0.199, Corel Painter 2015 14.0.0.728, Corel PDF Fusion 1.12 Build 16/04/2013 and earlier, and possibly other versions allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse wintab32.dll that is located in the same folder as an .cdr, .cpt, .pspimage, .rif or .pdf file.
Microsoft Windows TCP IP Arbitrary Write Local Privilege Escalation Exploit (MS14-070)
The TCP/IP Driver (tcpip.sys) present in Microsoft Windows fails to sufficiently validate memory objects used during the processing of a user-provided IOCTL. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges by sending a specially crafted IOCTL (0x00120028) to the vulnerable driver.
This update includes a module that executes a program designed to test a buffer overflow in glibc's __nss_hostname_digits_dots function. The function is used by the gethostbyname*() functions family used for name resolution. Under some circumstances, the use of those functions when the vulnerable underlying function is present, may lead to remote code execution, privilege escalation, or information disclosure.
