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.

An issue was discovered in MalwareFox AntiMalware. Improper access control in zam32.sys and zam64.sys allows a non-privileged process to register itself with the driver by sending IOCTL 0x80002010 and then using IOCTL 0x8000204C to \\.\ZemanaAntiMalware to elevate privileges.
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
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.
X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile.
Microsoft Windows Win32k Keyboard Layout Vulnerability Exploit (MS12-034) Update 6
This update adds support to Microsoft Windows 2003 64 bits edition ( DoS ), Microsoft Windows Vista 64 bits edition ( DoS ), Microsoft Windows 2008 64 bits edition ( DoS ) and Microsoft Windows Seven 64 bits edition ( DoS ).
This module exploits a Windows kernel vulnerability by loading a fake keyboard layout through a call to "NtUserLoadKeyboardLayoutEx" function with crafted parameters.
When the keyboard layout is processed by win32k.sys, it produces a kernel heap memory corruption.
Panda Global Protection AppFlt.sys Privilege Escalation Exploit
This module exploits a memory corruption vulnerability in the AppFlt.sys driver of Panda Global Protection when handling a specially crafted IOCTL request. This vulnerability allows unprivileged local users to execute code with SYSTEM privileges.
Microsoft Windows Win32k Keyboard Layout Vulnerability Exploit (MS10-073)
This module exploits a vulnerability on "win32k.sys" when a keyboard layout is loaded by the kernel.
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.
Microsoft .NET Runtime Optimization Service Privilege Escalation Exploit
The .NET Runtime Optimization Service, part of the .NET Framework, is prone to a privilege escalation vulnerability, which can be exploited by local unprivileged users to execute arbitrary code with SYSTEM privileges.
Microsoft Windows Win32k Font Parsing Vulnerability DoS (MS13-036)
This module exploits a vulnerability in Windows kernel (win32k.sys) when a crafted TTF font is open.
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.
Windows Win32k xxxClientAllocWindowClassExtraBytes Privilege Escalation Exploit
This vulnerability is caused by xxxClientAllocWindowClassExtraBytes callback in win32kfull!xxxCreateWindowEx. The callback causes the setting of a kernel struct member and its corresponding flag to be out of sync.
Linux OverlayFS Attr Local Privilege Escalation Exploit
The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges.
Linux Kernel CONFIG_X86_X32 Privilege Escalation Exploit
This module exploits a privilege escalation vulnerability in the Linux Kernel. The X86_X32 recvmmsg syscall does not properly sanitize the timeout pointer passed from userspace and allows a local attacker to escalate privileges.
Microsoft Windows win32kbase Use After Free MisterySnail NtGdiResetDC Privileged Escalation Exploit
CVE-2021-40449 is a use-after-free vulnerability in Win32k's NtGdiResetDC function. As with many other Win32k vulnerabilities, the root cause of this vulnerability lies in the ability to set user-mode callbacks and execute unexpected API functions during execution of those callbacks. The CVE-2021-40449 is triggered when the function ResetDC is executed a second time for the same handle during execution of its own callback.
Linux Kernel Netfilter Dup Netdev OOB Write Local Privilege Escalation Exploit
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges because of a heap out-of-bounds write. This is related to nf_tables_offload.
Linux Kernel Legacy Parse Param IU HO Local Privilege Escalation Exploit
A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system
Microsoft Sysmon Arbitrary File Delete Write Local Privilege Escalation Exploit
Vulnerability is in code responsible for ClipboardChange event that can be reached through RPC. Local users can send data to RPC server which will then be written in Sysmon directory.
Linux Kernel Netfilter UaF NF Tables Local Privilege Escalation Exploit
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.
Linux Kernel GSM Multiplexing Race Condition Local Privilege Escalation Exploit
This vulnerability allows local attackers to execute arbitrary code on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the n_gsm driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel.
Fortra's Robot Schedule Enterprise Agent for Windows prior to version 3.04 is susceptible to privilege escalation. A low-privileged user can overwrite the service executable. When the service is restarted, the replaced binary runs with local system privileges, allowing a low-privileged user to gain elevated privileges.
This module verifies the Mark Of The Web Vulnerability.
Windows ZIP extraction bug (CVE-2022-41049) lets attackers craft ZIP files, which evade warnings on attempts to execute packaged files, even if ZIP file was downloaded from the Internet.
