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.

Microsoft Windows Remote Desktop Protocol BlueKeep Use After Free Exploit
A remote code execution vulnerability exists in Remote Desktop Services formerly known as Terminal Services when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests, aka 'Bluekeep'.
Windows Win32k Elevation Of Privilege Exploit (CVE-2019-0803) 2
An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.
VUPlayer contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error in VUPlayer when handling .M3U files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .M3U file.
This module exploits a buffer overflow vulnerability during the processing of requested resources to cause a stack-based buffer overflow by requesting a resource with an overly long name.
Path traversal vulnerability in WinRAR when crafting the filename field of the ACE format (in UNACEV2.dll). When the filename field is manipulated with specific patterns, the destination (extraction) folder is ignored, thus treating the filename as an absolute path.
The vulnerability is caused due to a boundary error within the parsing of .CUE files, this can be exploited to cause a stack-based buffer overflow via a .CUE file with an overly long file string.
Microsoft Windows DCOM-RPC NTLM Reflection Elevation of Privilege Exploit
This update adds an exploit which implements the Rotten Potato technique to perform a Local Privilege Escalation.
It leverages on local DCOM DCE/RPC connections that can be reflected back to a listening TCP socket allowing access to an NTLM authentication challenge for LocalSystem user which can be replayed to the local DCOM activation service. An attacker who successfully exploited this vulnerability could bypass security and gain elevated privileges on a targeted system.

DATAC RealWin SCADA Server Remote Stack Buffer Overflow Exploit
This module exploits a buffer overflow vulnerability in RealWin SCADA Server. This vulnerability can be exploited remotely by sending a specially crafted packet to port TCP/910.
This module exploits a vulnerability in ZoneAlarm products when the 0x8400000F function is invoked with a specially crafted parameter. The IOCTL 0x8400000F handler in the VSDATANT.SYS device driver in ZoneAlarm products allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters to obtain escalated privileges.
This module exploits an error during processing of FORMAT records when loading Excel files into memory that can be exploited to corrupt memory via a specially crafted XLS file containing an out-of-bounds array index.
The vulnerability is caused due to a boundary error when parsing format strings containing a floating point specifier in the util.printf() JavaScript function.
A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system.
The specific flaw exists within the processing of CXP files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
Symantec Messaging Gateway performRestore OS Command Injection Exploit
Symantec Messaging Gateway is prone to an Authentication Bypass vulnerability that allows attackers to take advantage of an improper validation of user-supplied data in the RestoreAction.performRestore method.
An attacker can leverage this vulnerability to execute arbitrary code in the context of root.
