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.

Improvements to Bash Environment Variable Injection Exploits
This update add verification for CVE-2014-6278 to all available attack vectors.
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.

Kolibri WebServer HTTP POST Request Buffer Overflow Exploit
Kolibri Webserver is vulnerable to a stack buffer overflow as a result of failure to properly validate user-supplied input when handling HTTP POST requests.
Microsoft Windows OLE Packager INF File Remote Code Execution Exploit (MS14-060)
The OLE packager component (packager.dll) of Microsoft Windows will automatically download remote files referenced in embedded OLE objects within Office documents. In the case of .INF installer files, packager.dll will automatically run them without prompting the user. This can be abused to gain arbitrary code execution by creating an Office document with an embedded OLE object containing a reference to a remote INF file with specially crafted commands. This vulnerability can be exploited by convincing an unsuspecting user to open a specially crafted PowerPoint document.
Linux Kernel n_tty_write Privilege Escalation Exploit Update
This module exploits a vulnerability in the Linux Kernel. The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local attackers to escalate privileges triggering a race condition involving read and write operations with long strings. This update adds support for Ubuntu 14.04.

HP Network Node Manager I ovopi Option -L Buffer Overflow Exploit
This module exploits a stack-based buffer overflow in ovopi.dll which listens by default on a UDP port 696. When parsing option -L, the process blindly copies user supplied data into a fixed-length buffer allowing for an arbitrary write to occur.
Bash Environment Variables Remote Code Execution Exploit for SSH
A vulnerability in GNU Bash when processing trailing strings after function definitions in the values of environment variables allows remote attackers to execute arbitrary code via a crafted environment. This vulnerability can be leveraged to bypass restricted SSH access (i.e.
This update includes a module exploiting a vulnerability found in Bash. When using PureFTPd in conjuntion with the vulnerable Bash version for user authentication, a Core Impact agent is installed.
MediaWiki with DjVU or PDF file upload allows a remote attackers to execute arbitrary commands by exploting a bug in the with parameter in thumb.php while previewing the uploaded file.
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.
