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.

Product Name
Microsoft Windows Print Spooler Load Library Vulnerability Exploit (MS09-022)
This module takes advantage of an insufficient library path check in spoolsv.exe service to load a dll from an arbitrary directory with System user privileges.
Microsoft Windows Sysret Instruction Privilege Escalation Exploit (MS12-042)
On Intel CPUs, sysret to non-canonical addresses causes a fault on the sysret instruction itself after the stack pointer is set to guest value but before the current privilege level (CPL) is changed. Windows is vulnerable due to the way the Windows User Mode Scheduler handles system requests. This module exploits the vulnerability and installs an agent with system privileges.
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 allows local unprivileged users to execute arbitrary code with SYSTEM privileges.
Microsoft Windows Task Scheduler Service Privilege Escalation Exploit (MS10-092)
This module exploits a privilege escalation vulnerability in the Microsoft Windows Task Scheduler Service. This vulnerability is currently exploited by the Stuxnet malware.
Microsoft Windows TCP IP Arbitrary Write Local Privilege Escalation Exploit (MS14-070)
The TCP/IP Driver (tcpip.sys) present in Microsoft Windows fails to sufficiently validate memory objects used during the processing of a user-provided IOCTL. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges by sending a specially crafted IOCTL (0x00120028) to the vulnerable driver.
Microsoft Windows Token Kidnapping Local Privilege Escalation Exploit (MS09-012)
This module exploits a vulnerability in the way that Microsoft Windows manages the RPCSS service and improperly isolates processes running under the NetworkService or LocalService accounts. This can be exploited to execute arbitrary code with System privileges.
Microsoft Windows Tracing Registry Key ACL Privilege Escalation Exploit (MS10-059)
This module exploits incorrect access control lists (ACLs) on the Registry keys for the Tracing Feature for Services. By modifying the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Tracing\IpHlpSvc Registry key, it is possible for a limited account with impersonation privileges to force a SYSTEM service (IpHlpSvc) to connect to a controlled named pipe, and then impersonate IpHlpSvc in order to run arbitrary code with SYSTEM privileges.
Microsoft Windows TrueType Font Parsing Vulnerability Local Exploit (MS11-087)
When a crafted ".TTF" file is loaded by Windows Kernel this produces a kernel heap overflow. This module exploits this vulnerability filling the kernel memory via heap spraying and building a fake chunk header.
Microsoft Windows Win32k Improper Message Handling Vulnerability Exploit (MS13-005)
An elevation of privilege vulnerability exists when the Windows kernel improperly handles window broadcast messages. This module exploits the vulnerability, and installs an agent running as a medium integrity level process.
Microsoft Windows Win32k Keyboard Layout Vulnerability Privilege Escalation Exploit (MS12-047)
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.
Microsoft Windows Win32k Keyboard Layout Vulnerability Local DoS (MS12-047)
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.
Microsoft Windows Win32k TrackPopupMenu Null Pointer Dereference Privilege Escalation Exploit (MS14-058)
This module exploits a null pointer dereference in win32k.sys by abusing of xxxSendMessageTimeout function. The TrackPopupMenu API function is used to trigger the vulnerability.
After successful exploitation an agent will be installed. The process being exploited is the winlogon process. Execute the 'RevertToSelf' module after exploitation to get SYSTEM access.
Norman Security Suite Nprosec.sys Privilege Escalation Exploit
This module exploits a memory corruption vulnerability in Norman Security Suite Nprosec.sys driver when handling IOCTL 0x00220210. This vulnerability allows unprivileged local users to execute code with SYSTEM privileges. This module will elevate the privileges of the current agent instead of installing a new one.
Novell NetWare Client NWFS.SYS Local Privilege Escalation Exploit
This module exploits a vulnerability in Novell NetWare Client 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.
Novell NetWare Client NWFILTER.SYS Local Privilege Escalation Vulnerability
This module exploits a vulnerability in Novell NetWare Client when handling a specially crafted IOCTL. The vulnerability allows local users to overwrite memory and execute arbitrary code via a malformed Interrupt Request Packet (Irp) parameters.
A vulnerability exists in the system component that handles the Virtual DOS Machine (VDM) subsystem. A local attacker may exploit this vulnerability in order to run code with elevated privileges, fully compromising the vulnerable computer. This module exploits that vulnerability to change the agent's process access token, gaining SYSTEM privileges.
The nfds (number of file descriptors) argument to the select() system call is a signed integer. Bounds checking code in the kernel evaluates this argument in a signed context. By passing negative arguments it is possible to cause the kernel to copy a large amount of data from userspace into a buffer on the stack, overflowing the allocated space. This module exploits the vulnerability to lower the system security level to -1 and launches an agent with root privileges.
