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.

Linux Kernel x86_64 Ptrace Sysret Privilege Escalation Exploit
On x86_64 Intel CPUs, sysret to a non-canonical address causes a fault on the sysret instruction itself after the stack pointer has been set to a usermode-controlled value, but before the current privilege level (CPL) is changed. A flaw in the ptrace subsystem of the Linux kernel allows a tracer process to set the RIP register of the tracee to a non-canonical address, which is later used when returning to user space with a sysret instruction instead of iret after a system call, thus bypassing sanity checks that were previously introduced to fix related vulnerabilities.
Embarcadero ERStudio Data Architect TSVisualization ActiveX loadExtensionFactory Buffer Overflow Exploit
The vulnerability lies in the failure to validate the size of the input buffer before copying it into a fixed-size buffer on the stack within the handling of the loadExtensionFactory method.
Microsoft Windows Ancillary Function Driver Double Free Vulnerability Exploit (MS14-040) Update 2
This module exploits a double-free vulnerability in "afd.sys" by calling to "AfdTransmiteFile" function with crafted parameters. This update adds support to Impact 2014 R2.
Adobe Reader X AdobeCollabSync Buffer Overflow Sandbox Bypass Exploit
This module allows an agent running in the context of AcroRd32.exe with Low Integrity Level/AppContainer Integrity Level to escalate privileges in order to install a new agent that will run with Medium Integrity Level.
Foxit Reader is prone to a vulnerability that may allow the loading and execution of any library file named imgseg.dll, if this dll is located in a determined subfolder where a .PDF file is.

Openfiler Remote Code Execution Exploit Update
Insufficient sanitization in Openfile's /admin/system.html 'Hostname' field, leads to remote code execution. This update fixes the exploit category.
A missing boundary check in the TLS Heartbeat extension in OpenSSL can be abused by remote attackers to read up to 64 kb of memory from the server. This memory disclosure vulnerability can be used by remote unauthenticated attackers to obtain sensitive information from the affected server, including private keys and session cookies. This update adds features to the module, like the ability to read 64 kb of data from vulnerable services, reporting the results in the Module Output window, and saving the memory dumps to disk.
Microsoft Windows Ancillary Function Driver Double Free Vulnerability Exploit (MS14-040) Update
This module exploits a double-free vulnerability in "afd.sys" by calling to "AfdTransmiteFile" function with crafted parameters. This module adds support to Microsoft Windows 2003, Windows Vista, Windows 2008 and Windows 8.1
A vulnerability within the webvact ActiveX control when handling NodeName parameter with overly long strings can be exploited to cause stack-based buffer overflows in Advantech WebAccess Browser-based HMI/SCADA Software.
By providing an overly long string to the AccessCode2 parameter, an attacker may be able to overflow the static stack buffer. The attacker may then execute code on the target device remotely.
A stack buffer overflow occurs when copying a user supplied input to a fixed size stack buffer without boundary check leading to overwrite the SEH and the return address. The copying procedure stops when a null word is found and no size check is proceeded.

Microsoft Internet Explorer IESetProtectedModeRegKeyOnly Protected Mode Escape Exploit (MS13-097)
The IESetProtectedModeRegKeyOnly() function in the ieframe.dll library of Microsoft Internet Explorer calls the RegCreateKeyEx registry function when running with Medium Integrity Level over a registry key that is writable by a sandboxed IE instance. This can be abused to overwrite IE's Elevation Policy by creating symbolic links in the Windows Registry in order to escape from the Internet Explorer Protected Mode sandbox.
