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. Witten by our own internal team, 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 specific flaw exists within processing of the AddStringUserProperty method within the UCCDRAW.UCCDrawCtrl.1 ActiveX control of UCanCode E-XD Visualization Enterprise Suite. The process does not properly validate a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process. This module runs a web server waiting for vulnerable clients (Internet Explorer 6, 7, 8) to connect to it.
Exploits / OS Command Injection / Known Vulnerabilities
Impact
Linux Kernel SO_SNDBUFFORCE Privilege Escalation Exploit
This module exploits a signedness issue in the Linux Kernel. The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to escalate privileges. This module performs a CAP_NET_ADMIN to root privilege escalation.
Microsoft Windows COM Aggregate Marshaler Type Confusion Exploit
This module exploits a vulnerability in the IRemUnknown2 COM interface, an attacker can abuse the fact that the local unmarshaled proxy can be for a different interface to that requested by QueryInterface resulting in a type confusion, which can be leveraged to elevate privileges.
This module exploits a vulnerability in Sparklabs Viscosity. By abusing a configuration channel between the application and the underlying service, an attacker can trigger the loading of a DLL from a path under his control, gaining SYSTEM privileges.

Impact
Microsoft Office Word OLE2Link OLE Object Exploit
This module exploits a vulnerability in Microsoft Office Word. The flaw is related in how Microsoft Word handles OleLink objects. It is possible to open a RTF file and execute arbitrary code in vulnerables installations of Microsoft Office Word. This vulnerability was originally seen being exploited in the wild starting in October 2016.
Microsoft Windows LSASS Memory Corruption DoS (MS17-004)
This module exploits an exceptional condition in "lsasrv.dll" by sending a crafted "Session Setup Request" SMBv1 or SMBv2 packet that is affected during the NTML Auth message.
PHPMailer is prone to a abuse the mailSend function. This vulnerability allows remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code via a \" (backslash double quote) in a crafted Sender property. The attack will not leave any trace. This exploit installs an OS Agent.
Sync Breeze Enterprise GET Buffer Overflow Exploit
Sync Breeze Enterprise is prone to a buffer-overflow vulnerability when handling a crafted GET request, this can trigger an overflow in a finite-sized internal memory buffer, and install an agent with SYSTEM privileges.
The vulnerability exists within the WdMacCtl ActiveX control This module runs a web server waiting for vulnerable clients (Internet Explorer 8) to connect to it.
Trend Micro InterScan Web Security Virtual Appliance doPostMountDevice OS Command Injection Exploit
Trend Micro InterScan Web Security Virtual Appliance is prone to an OS command injection which allows attackers the execution of system commands.
