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.

The best practice for web applications built on top of the Apache Struts 2 framework is to switch off Developer Mode (struts.devMode parameter in the struts.xml configuration file) before going into production. When devMode is left enabled, attackers can gain remote code execution by setting the 'debug=command' URL parameter and sending OGNL expressions through the 'expression' URL parameter. This module takes advantage of this misconfiguration scenario in order to deploy an agent in the target system.

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.
Microsoft Internet Explorer CMarkup Object Use-After-Free Exploit(MS14-021) Update
Use-after-free vulnerability in Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to the CMarkup::IsConnectedToPrimaryMarkup function, as exploited in the wild in April 2014. This update adds support for Internet Explorer 8 and some specific patch versions of Internet Explorer 10
IcoFX is prone to a security vulnerability when processing .ICO files. This vulnerability could be exploited by a remote attacker to execute arbitrary code on the target machine, by enticing the user of IcoFX to open a specially crafted icon file.
This module exploits a vulnerability in OpenSSL by sending a "Change Ciper Spec" message to the server. This vulnerability allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake.
A logical error in sudo when the env_reset option is disabled allows local attackers to define environment variables that were supposed to be blacklisted by sudo. This can be exploited by a local unprivileged attacker to gain root privileges by manipulating the environment of a command that the user is legitimately allowed to run with sudo.
HP SiteScope issueSiebelCmd Remote Code Execution Exploit
This module exploits a remote code execution vulnerability in HP SiteScope. The vulnerability exists in the APISiteScopeImpl web service, specifically in the issueSiebelCmd method, which allows the user to execute arbitrary commands without authentication.
The KingSCADA application has a stack-based buffer overflow vulnerability where the application overwrites the structured exception handler (SEH). An attacker could send a specially crafted packet to KingSCADA, and the application would handle the packet incorrectly, causing a stack-based buffer overflow.
Microsoft Windows Shell File Association Vulnerability Exploit (MS14-027)
When the "HKEY_CURRENT_USER\Software\Classes\exefile" registry key is modified by this exploit and a Windows or third party service calls to the "ShellExecute" function, an invalid association file is produced, finalizing the attack with the execution of a crafted program instead of the original program.
Microsoft Windows Win32k Information Disclosure Vulnerability DoS (MS14-015)
This module exploits a vulnerability in "win32k.sys" by calling to "NtUserValidateHandleSecure" function with crafted parameters. This is a documentation update from the original module "Microsoft Windows Win32k IsHandleEntrySecure Null Pointer Dereference DoS".
Borland Silk Central TeeChart ActiveX Control AddSeries Untrusted Pointer Exploit
The specific flaw exists within the Borland Silk Central TeeChart ActiveX control. The control suffers from an untrusted pointer dereference vulnerability because it blindly calls an attacker-supplied memory address. An attacker can exploit this condition to achieve code execution under the context of the browser process.
