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 Overlayfs Local Privilege Escalation Exploit
This module exploits a vulnerability in Linux. The overlayfs filesystem does not correctly check file permissions when creating new files in the upper filesystem directory. This can be exploited by an unprivileged process in kernels with CONFIG_USER_NS=y and where overlayfs has the FS_USERNS_MOUNT flag, which allows the mounting of overlayfs inside unprivileged mount namespaces.
Microsoft Windows Win32k ClientCopyImage Privilege Escalation Exploit(MS15-051)
An elevation of privilege vulnerability exists when the Win32k.sys kernel-mode driver improperly handles objects in memory. The vulnerability exists in the Windows OS process of creating windows for applications. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode.
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.
This module exploits a vulnerability in Avast Antivirus ASWMON.SYS driver when handling a specially crafted IOCTL request. The vulnerability allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters.
The MsIo64.sys and MsIo32.sys drivers in Patriot Viper RGB allow local users (including low integrity processes) to read and write to arbitrary memory locations, and consequently gain NT AUTHORITY\SYSTEM privileges, by mapping \Device\PhysicalMemory into the calling process via ZwOpenSection and ZwMapViewOfSection.
Sudo Root With User ID Local Privilege Escalation Exploit (CVE-2019-14287)
This module exploits a flaw in the way sudo implemented running commands with arbitrary user ID. If a sudoers entry is written to allow the attacker to run a command as any user except root, this flaw can be used by the attacker to bypass that restriction.
Sophos SafeGuard Enterprise before 8.00.5, SafeGuard Easy before 7.00.3, and SafeGuard LAN Crypt before 3.95.2 are vulnerable to Local Privilege Escalation via multiple IOCTLs. This update fixes an error in the injection.
Windows Macrovision (SECDRV.SYS) Memory Corruption Exploit Update
This module exploits a vulnerability in Windows XP and Windows 2003 when the 0xCA002813 function is invoked with a specially crafted parameter. The IOCTL 0xCA002813 handler in the SECDRV.SYS device driver in Macrovision products, installed by default in Windows XP and Windows 2003, allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters.
This update corrects the CVE number and adds Windows 2003 as Supported System.
An error handling mechanism in the kernel of Mac OS X, provides the ability to control programs when certain types of errors are encountered. This module uses this mechanism to execute arbitrary code in privileged programs if an error is encountered. This update adds support for Mac OS X (i386)
Microsoft Windows WPAD Elevation of Privilege Exploit (MS16-077)
An elevation of privilege vulnerability exists in Microsoft Windows when the Web Proxy Auto Discovery (WPAD) protocol falls back to a vulnerable proxy discovery process. An attacker who successfully exploited this vulnerability could bypass security and gain elevated privileges on a targeted system.
Incorrect signedness comparison in the ioctl handler of the atkbd keyboard driver in the FreeBSD kernel can be leveraged by a local unprivileged user to overwrite a portion of the kernel memory, thus allowing the attacker to gain root privileges on the affected system.
Microsoft Windows splwow64 Untrusted Pointer Dereference Privilege Escalation Exploit
The specific flaw exists within the user-mode printer driver host process splwow64.exe. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privileges from low integrity and execute code in the context of the current user at medium integrity.
Microsoft Windows Class Name String Atom Privilege Escalation Exploit (MS12-041)
An error in the way that the Windows kernel handles string atoms when registering a new window class allows unprivileged users to re-register atoms of privileged applications.
This vulnerability can be exploited by local unprivileged users to execute arbitrary code with SYSTEM privileges.
Microsoft Windows Win32k Integer Overflow DoS (MS13-101)
This module exploits a vulnerability in win32k.sys by calling to "NtGdiGetTextExtent" function with crafted parameters.

Microsoft Windows Ancillary Function Driver for WinSock Elevation of Privilege Vulnerability Exploit
The Ancillary Function Driver (AFD.sys) present in Microsoft Windows is vulnerable to an arbitrary memory overwrite. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges by sending a specially crafted IOCTL to the vulnerable driver.
Microsoft Windows SystemDefaultEUDCFont Privilege Escalation Exploit
This module exploits a privilege escalation vulnerability in Microsoft Windows by setting a specially crafted SystemDefaultEUDCFont value in the HKEY_CURRENT_USER\EUDC Registry key, and then calling EnableEUDC() function in GDI32 library. It will enable local unprivileged users to gain SYSTEM privileges.
Microsoft Windows Administrator UAC Elevation Bypass
This module abuses a design flaw in the way Microsoft Windows implements a UAC whitelist. The flaw could allow a process running with Medium Integrity to elevate itself to High Integrity without a UAC prompt when the process is run from an account in the administrators group.
