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 Excel Featheader Record Memory Corruption Vulnerability Exploit (MS09-067)
A remote code execution vulnerability exists in the way that Microsoft Office Excel handles specially crafted Excel files that include a malformed record object. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
WARNING: This is an early release module. This is not the final version of this module.
A Reflected Cross Site Scripting vulnerability was found in the atksearch[contractnumber], atksearch_AE_customer[customer] and atksearchmode[contracttype] variables within the 'Organisation Contracts' administration page. This is because the application does not properly sanitise the users input.
Symantec ConsoleUtilities ActiveX Control Buffer Overflow Exploit
This module exploits a vulnerability in the AeXNSConsoleUtilities.dll control included in the Symantec ConsoleUtilities application. The exploit is triggered when the BrowseAndSaveFile method processes a long string argument resulting in a stack-based buffer overflow.
BigAnt IM Server HTTP GET Request Remote Buffer Overflow Exploit Update
This module exploits a vulnerability in the AntServer Module (AntServer.exe) that can be exploited to cause a stack-based buffer overflow by sending a specially crafted, overly long HTTP GET request to default port 6660/TCP.
This update adds support for the latest version of the software, which is still vulnerable to the attack.
There is an authentication vulnerability in the Windows debugging subsystem (smss). This allows any user to obtain a handle with any access of any process running. With this handle an agent is injected in a SYSTEM process.
Omni-NFS Enterprise FTP Server Buffer Overflow Exploit
This vulnerability is caused by a buffer overflow in Omni-NFS Enterprise FTP Server, due to its lack of checking of user-supplied data within FTP requests.
Microchip MPLAB IDE MCP File Handling Remote Buffer Overflow Exploit
This vulnerability arises from the way MPLAB IDE processes IDE Project files with extension of .mcp. It could lead to a critical buffer overflow error that allows hackers to execute malicious code on users systems.
Viper RGB Driver Kernel Buffer Overflow Local Privilege Escalation Exploit
This module exploits a buffer overflow vulnerability in Viper RGB MsIo64.sys vulnerability allows unprivileged local users to execute code with SYSTEM privileges.
Citrix ADC and Gateway Directory Traversal Vulnerability Exploit
Citrix Application Delivery Controller (ADC) and Citrix Gateway are prone to a directory traversal vulnerability that allows attackers to upload an XML file via newbm.pl and execute system commands.
Debian OpenSSL Predictable Random Number Generation Exploit Update 2
This module exploits the random number generator in Debian's OpenSSL package being predictable. This vulnerability is used to generate SSH keys and to install an agent into the target host.
The exploit will generate the complete vulnerable keyspace, and will try to log as the provided user. If the user is root, the agent will have superuser capabilities.
This update improves exploit performance when used through Network Attack and Penetration RPT.
Microsoft Internet Explorer Scripting Engine Memory Corruption Exploit
A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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.
Total Video Player M3U Playlist Buffer Overflow Exploit
Total Video Player contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error in Total Video Player when handling .M3U files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .M3U file
VMware Workstation VMX Process COM Class Hijack Local Privilege Escalation Exploit
VMware Workstation (15.x before 15.0.3, 14.x before 14.1.6) running on Windows does not handle COM classes appropriately. Successful exploitation of this issue may allow hijacking of COM classes used by the VMX process, on a Windows host, leading to elevation of privilege.
The flaw exists in the GetUserPasswd function in BwPAlarm.dll due to improper validation of user-supplied data before copying the data to a fixed size stack-based buffer when processing an IOCTL 70603 RPC message.
An internal memory buffer may be overrun while handling long MKD commands. This condition may be exploited by attackers to ultimately execute instructions with the privileges of the CesarFTP process.
