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.

Corel VideoStudio Pro X7 and FastFlix u32ZLib DLL Hijacking Exploit
Untrusted search path vulnerability in Corel VideoStudio Pro X7 17.0.0.249 and Corel FastFlix 17.0.0.249 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 u32ZLib.dll that is located in the same folder as an .vsp or .vfp file.
Microsoft Windows Telnet Server ProcessDataReceivedOnSocket DoS (MS15-002) Update
A stack-based buffer overflow in the ProcessDataReceivedOnSocket function in the Microsoft Telnet Server Helper (tlntsess.exe) can be used by remote unauthenticated attackers to render the Telnet server unresponsive.
This update improves the way in which this module detects if the attack was successful.
Microsoft Windows Telnet Server ProcessDataReceivedOnSocket DoS (MS15-002)
A stack-based buffer overflow in the ProcessDataReceivedOnSocket function in the Microsoft Telnet Server Helper (tlntsess.exe) can be used by remote unauthenticated attackers to render the Telnet server unresponsive.
Untrusted search path vulnerability in Corel Painter 2015 14.0.0.728 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 wacommt.dll that is located in the same folder as an .rif file.
Untrusted search path vulnerability in 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 quserex.dll that is located in the same folder as an .pdf file.
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 introduces the option to use NTLM hashes for authentication and Network RPT-AP integration.
The specific flaw exists within the PocketNetNVRMediaClientAxCtrl.NVRMediaViewer.1 control. The SaveCurrentImageEx method copies an attacker provided filename into a fixed size buffer.
Microsoft Windows Administrator UAC Elevation Bypass Update
This module abuses a design flaw in the way Microsoft Windows implements a UAC whitelist. The flaw could allow a process running with Medium Integrity to elevate itself to High Integrity without a UAC prompt when the process is run from an account in the administrators group.
Linux Kernel libfutex Privilege Escalation Exploit
This module exploits a vulnerability in the Linux Kernel. The futex_requeue function in kernel/futex.c in the Linux kernel does not ensure that calls have two different futex addresses, which allows local attackers to gain privileges via a crafted FUTEX_REQUEUE command.
Microsoft Windows Schannel Heap Overflow DoS (MS14-066) Update
This module exploits a vulnerability in "schannel.dll" by sending a crafted certificate packet to the "Internet Information Services" server via TLS protocol producing a heap overflow in the critical LSASS Windows process.
This update reduces the time of the target exploitation.
Besides, all targets supported are added in the documentation.
This update makes a new version of DLLMaker library available to exploits.
New features and fixes:
+ Compatibility with PROCESS_MITIGATION_ASLR_POLICY process creation flags.
+ fixes IAT inconsistencies
+ new sections: .reloc, .rsrc.
+ adds VS_VERSION_INFO resource

Microsoft Internet Explorer CInput Object Use-After-Free Exploit(MS14-035)
A use after free vulnerability exists in Internet Explorer. The vulnerability is due to accessing a freed CInput object in memory.
A remote attacker could exploit this vulnerability by enticing the target user to open a malicious web page. In the case of successful exploitation, arbitrary attacker code would be executed in the security context of the target user.
Microsoft Windows Schannel Heap Overflow DoS (MS14-066)
This module exploits a vulnerability in "schannel.dll" by sending a crafted certificate packet to the "Internet Information Services" server via TLS protocol producing a heap overflow in the critical LSASS Windows process.
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 Windows OLE Automation Array Remote Code Execution Exploit (MS14-064) Update
An integer overflow in OLE allows remote code execution. This update contains a module exploiting the vulnerability by hosting a web site and epxloiting connecting Internet Explorer browsers.
