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.

Product Name
Microsoft Windows SMB Client Transaction DoS (MS10-020)
This module exploits a remote vulnerability in Microsoft Windows SMB client allowing the attacker to cause a DoS in the remote host.
Microsoft Windows SMB Pathname Overflow DoS (MS10-012)
This module creates many subfolders into a writeable shared folder in the target. After that it sends an equivalent command like "move \\target_ip\shared_folder\folder1\folder2\..\foldern\*.* \\target_ip\shared_folder" producing an integer underflow in "srv.sys".
Microsoft Windows SMB Pool Overflow DoS (MS10-054)
This module exploits a Windows kernel remote vulnerability on the srv.sys driver via a malformed SMB packet. It could allow an attacker to connect to a shared folder and send a specially crafted SMB message to an affected system causing a denial of service.
Microsoft Windows SMB Server Stop Responding DoS (MS11-048)
This module exploits a vulnerability on "srvnet.sys" sending to the target incomplete packets via SMB v1. Once the bug was triggered, this module keeps the target unavailable until the block time is over.
Microsoft Windows SMB Trans Buffer Overflow DoS (MS09-001)
This module exploits a remote vulnerability on the CreateWithSdOrEa SMB command on the srv.sys driver. It could allow an attacker to connect to a shared folder and send a specially crafted SMB message to an affected system causing a denial of service.
Microsoft Windows SMTP Server MX Record Vulnerability DoS (MS10-024)
This module exploits a vulnerability on smtpsvc.dll ( "Simple Mail Transfer Protocol" service ) via a malformed MX response packet sent by the spoofed DNS Server. This module exploits a vulnerability on smtpsvc.dll ("Simple Mail Transfer Protocol" service) via a malformed MX response packet sent by the spoofed DNS Server. When the SMTP Client ( this module ) sends an email to "[email protected]" ( "XXXXX" is a random number between 0 and 65536 ), the SMTP Server tries to resolve the IP of "dominioXXXXX.com" domain.
Microsoft Windows SRV.SYS Server Driver DoS (MS06-035)
This module exploits a remote vulnerability that could allow an attacker to send a specially crafted SMB message to an affected system causing a denial of service.
Microsoft Windows TCPIP SACK Remote DoS (MS10-009)
This module exploits a memory corruption in the Microsoft Windows TCP/IP implementation by sending a sequence of TCP/IP packets with a specially crafted Selective Acknowledgement (SACK) values.
Microsoft Windows TCPIP Timestamp Remote DoS (MS09-048)
This module exploits a memory corruption in the Microsoft Windows TCP/IP implementation by sending a sequence of TCP/IP packets with a specially crafted Timestamp values.
Microsoft Windows TCP IPv6 Router Advertisement Message DoS (MS14-006)
This module exploits a vulnerability in the Windows kernel "tcpip.sys" driver by sending a lot of "ICMPv6 Router Advertisement" messages to the target finalizing it in a Stop Responding target behavior.
Linux TCP ICMPv6 Router Advertisement Flooding Vulnerability DoS
This module exploits a vulnerability in the Linux kernel by sending a lot of "ICMPv6 Router Advertisement" messages to the target finalizing it in a Stop Responding target behavior.
Microsoft Windows TCP TimeStamp Option Vulnerability DoS (MS14-031)
This module exploits a vulnerability in "tcpip.sys" by sending a large number of TCP packets with the Time Stamp option enabled. When a TCP packet is sent with a Time Stamp number smaller than the previous, the packet is added in a list an it's never removed. After sending many packets, the 139 TCP port is disabled to receive new connections.
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. This module will crash the tlntsess.exe Helper process, which is in charge of handling a client connection.
Microsoft Windows TrueType Font Parsing Vulnerability Clientside DoS (MS11-087)
This module causes a DoS in win32k.sys when attempts are made to render a malformed embedded font. This module runs a web server waiting for vulnerable clients (Internet Explorer) to connect to it.
Microsoft Windows Web Services on Devices Memory Corruption DoS (MS09-063)
The vulnerability is caused due to a WSD message with a long header value, this can lead to memory corruption within the process hosting WSDApi.dll. This can cause the service or application to crash. To be clear, the vulnerability is in the Windows module used to interact with devices that support Web Services on Devices, and does not affect the devices themselves.
Microsoft Windows Win32k Cursor Object Double Free Vulnerability DoS (MS15-010)
A double free condition in win32k.sys can be triggered by first linking and then destroying a set of Cursor Objects. This allows unprivileged local user to cause null dereference in kernel mode, which produces a BSoD.
Microsoft Windows Win32k Divide Error Exception DoS (MS13-046)
When the win32k.NtGdiScaleViewportExtEx function uses to divide one crafted parameter sent from user, the final result is a "divide error exception" that produces a BSoD.
Microsoft Windows Win32k Font Parsing Vulnerability ClientSide DoS (MS13-036)
This module exploits a vulnerability in win32k.sys when a crafted OTF file is open by Internet Explorer. This module runs a web server waiting for vulnerable clients (Internet Explorer) to connect to it.
Microsoft Windows Win32k Information Disclosure Vulnerability DoS (MS14-015)
The function win32k!IsHandleEntrySecure() doesn't properly check if 'pW32Job' field of 'tagPROCESSINFO' structure for current process contains non-zero value. This allows unprivileged local user to cause null dereference in kernel mode, which produces a BSoD.
Microsoft Windows Win32k Integer Overflow DoS (MS13-101)
When the "RFONTOBJ::bTextExtent" function located in win32k.sys ( Windows kernel ) uses to divide one crafted parameter sent from user, the final result is a "divide error exception" that produces a BSoD.
