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.

This module exploits a vulnerability in various ASROCK utilities. The low level access drivers at the core of these utilities expose dangerous functionality to low privilege processes, a local attacker can read/write arbitrary kernel memory, which can be leveraged to elevate privileges.
Kingsoft Internet Security Local Privilege Escalation Exploit
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Kingsoft Internet Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaws exists within the processing of IOCTL 0x80030004 or 0x80030008 by the KWatch3.sys (internet security) kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in a kernel stack buffer overflow.
The waitid implementation in upstream kernels did not restrict the target destination to copy information results. This can allow local users to write to otherwise protected kernel memory, which can lead to privilege escalation.
This update fixes the way non-vulnerable targets are handled

Linux Looney Tunables GLIBC Local Privilege Escalation Exploit Update
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
This update contains a minor fix in the exploit time out.
Microsoft Windows Win32k Privilege Escalation Exploit (MS16-135)
This module exploits a vulnerability in win32k.sys by setting a Window as WS_CHILD and sending a special key combination to this one.
WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations. Since this module is not the final version it may contain bugs or have limited functionality and may not have complete or accurate documentation.
MSI Ambient Link Local Privilege Escalation Exploit
Multiple stack buffer overflows were found in the MSI AmbientLink MsIo64 driver when processing IoControlCode (IOCTL) 0x80102040, 0x80102044, 0x80102050, 0x80102054. Local attackers, including low integrity processes, can exploit these vulnerabilities and consequently gain NT AUTHORITY\SYSTEM privileges.
Microsoft Windows WalletService Elevation of Privilege Vulnerability Exploit
An elevation of privilege vulnerability exists in the way that the Windows WalletService handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
Microsoft Windows Ws2ifsl UaF Local Privilege Escalation Exploit
An elevation of privilege vulnerability exists in the way that ws2ifsl.sys (Winsock) handles objects in memory, aka 'Windows Elevation of Privilege Vulnerability'
Linux PTRACE_TRACEME Local Privilege Escalation Exploit
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker).
Windows Win32k Elevation Of Privilege Exploit (CVE-2019-0803) 2
An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.
Microsoft Windows DCOM-RPC NTLM Reflection Elevation of Privilege Exploit
This update adds an exploit which implements the Rotten Potato technique to perform a Local Privilege Escalation.
It leverages on local DCOM DCE/RPC connections that can be reflected back to a listening TCP socket allowing access to an NTLM authentication challenge for LocalSystem user which can be replayed to the local DCOM activation service. An attacker who successfully exploited this vulnerability could bypass security and gain elevated privileges on a targeted system.
Windows Common Log File System Driver Local Privilege Escalation Exploit
The cause of the vulnerability is due to the lack of a strict bounds check for the SignaturesOffset field in the Base Block for the base log file (BLF) in CLFS.sys. This issue can lead to a Privilege Escalation.
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.
Sudo Setcmnd Heap Buffer Overflow Local Privilege Escalation Exploit
Sudo before 1.9.5p2 has a Heap-based Buffer Overflow, allowing privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character.
Cisco AnyConnect Posture Security Service TOCTOU Local Privilege Escalation Exploit
The Security Service of Cisco AnyConnect Posture (HostScan) for Windows incorrectly restricts access to internal IPC commands. This could enable low-privileged users to achieve NT AUTHORITY\SYSTEM privileges by sending crafted IPC commands.
This module bypasses CVE-2021-1366 by abusing a Time-of-check Time-of-use (TOCTOU) Race Condition in the priv_file_copy command.
PolicyKit pkexec Elevation of Privilege Vulnerability Exploit
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code.
