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.

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.
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.

Apple Mac OS X XPC Entitlements Local Privilege Escalation Exploit
The Admin framework in Apple OS X contains a hidden backdoor API to gain root privileges. A local user can exploit this flaw in the checking of XPC entitlements.
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.
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.

In VirIT eXplorer Anti-Virus, the VIAGLT64.SYS driver file contains an Arbitrary Write vulnerability, and can be exploited to elevate privileges from a local account to SYSTEM.
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 AFD AfdSendMessage Privilege Escalation Exploit
The Ancillary Function Driver (AFD.sys) present in Microsoft Windows is vulnerable to a double-fetch that causes an integer overflow, which can result in out-of-bounds memory write to non-paged pool memory. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges by calling to the WSASendMsg function with crafted parameters.
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 UPnP Device Host Local Privilege Escalation Exploit
This module exploits two vulnerabilities (CVE-2019-1405 & CVE-2019-1322) in order to get SYSTEM privileges. The first one "UPnP Device Host" allows us to get SERVICE privileges. The second one "Update Orchestrator Service" allows us to escalate from SERVICE to SYSTEM.
