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. Witten by our own internal team, 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.

MSI Dragon Center Denial of Service Exploit
This module exploits MODAPI.sys in MSI Dragon Center 2.0.104.0 which allows low-privileged users to write an arbitrary value to a Model-Specific Register (MSR) at the specified address.
Lexmark Universal Printer Driver Local Privilege Escalation Exploit
The Lexmark Universal Print Driver version 2.15.1.0 and below, G2 driver 2.7.1.0 and below, G3 driver 3.2.0.0 and below, and G4 driver 4.2.1.0 and below are affected by a privilege escalation vulnerability. A standard low priviliged user can use the driver to execute a DLL of their choosing during the add printer process, resulting in escalation of privileges to SYSTEM.
Linux Kernel eBPF OOB Read Write ALU32 Local Privilege Escalation Exploit
The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e ("bpf: Fix alu32 const subreg bound tracking on bitwise operations") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.
MSI Dragon Center Local Privilege Escalation Exploit
The MsIo64.sys driver before 1.1.19.1016 in MSI Dragon Center before 2.0.98.0 has a buffer overflow that allows privilege escalation via a crafted 0x80102040, 0x80102044, 0x80102050, or 0x80102054 IOCTL request.
A vulnerability in Pulse Connect Secure could allow an authenticated administrator to perform a file write via a maliciously crafted archive uploaded in the administrator web interface.
A JSON deserialization vulnerability present in the test alert actions allows remote attackers to execute arbitrary code on affected installations of SolarWinds Network Performance Monitor. Authentication is not required to exploit this vulnerability.
Microsoft Windows Print Spooler PrintNightmare Remote Code Execution Exploit
The vulnerability has been dubbed PrintNightmare and is tracked as CVE-2021-34527. The flaw is due to the Windows Print Spooler service improperly performing privileged file operations. Microsoft says the flaw can be exploited by an authenticated user calling RpcAddPrinterDriverEx(). When exploited, an attacker gains SYSTEM privileges and can execute arbitrary code, install programs, view, change, or delete data or create new accounts with full user rights.
This update adds the ability to choose an external agent for the smb file share.
Microsoft Exchange MeetingPollHandler Deserialization Remote Code Execution Vulnerability Exploit
Deserialization vulnerability in Microsoft Exchange MeetingPollProposeOptionsPayload.GetRequests() method. This method can be triggered with an HTTP request and with a specially crafted XML payload it can lead to OS command execution within the context of the w3wp.exe process which has SYSTEM level privileges.
VMware vCenter Server Virtual SAN Health Check plug-in Remote OS Command Injection Exploit
A java unsafe reflection and a Server Side Request Forgery vulnerabilities present in ProxygenController class of VMware vCenter Server Virtual SAN Health Check plugin allows remote attackers to execute commands in the context of the vsphere-ui user account.
Microsoft Windows SMBv3 SMBGhost Remote Code Execution Exploit
A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 3.1.1 (SMBv3) protocol handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server.
Microsoft Windows Print Spooler PrintNightmare Local Privilege Escalation Exploit
A Local Privilege Escalation vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges.
Cisco AnyConnect Posture Security Service TOCTOU Local Privilege Escalation Exploit Update
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.
This update adds code to launch the exploit for CVE-2021-1366 if the detected version is vulnerable to it.
Microsoft Windows win32kbase Use After Free using Direct Composition Privileged Escalation Exploit
The vulnerability is an Use After Free Privilege Escalation in win32kbase and occurs in the DirectComposition::CInteractionTrackerBindingManagerMarshaler::SetBufferProperty function, which is the handler for the SetResourceBufferProperty command of a CInteractionTrackerBindingManagerMarshaler.
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.
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.

Microsoft Windows Graphics Component Elevation of Privilege Vulnerability Exploit
An elevation of privilege vulnerability exists in Windows when the DirectComposition 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.
Apache Unomi allows conditions to use OGNL and MVEL scripting which offers the possibility to call static Java classes from the JDK that could execute code with the permission level of the running Java process.
