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 the JetAudio ActiveX Control (JetFlExt.dll). The exploit is triggered when a special string argument is processed by the DownloadFromMusicStore() method resulting in a stack-based buffer overflow.
This module exploits a vulnerability in DHCP Server in OpenBSD. The vulnerability is caused due to the improper handling of DHCP requests within dhcpd in the cons_options() function in options.c. This cause a stack-based buffer corruption by sending a specially crafted DHCP request specifying a maximum message size smaller than 278.
This module exploits a buffer overflow vulnerability in the Shared Trace Service (ovtrcsvc.exe) of the HP OpenView application. The exploit triggers a stack-based buffer overflow by sending a specially crafted packet to port 5053/TCP of the vulnerable system and installs an agent if successful.
This module exploits a vulnerability in the Microsoft Windows NAT Helper Component (ipnathlp.dll) when Internet Connection Sharing is enabled, sending a specially crafted DNS query.
This module exploits a vulnerability in Linux for x86_64. The IA32 system call emulation functionality does not zero extend the eax register after the 32bit entry path to ptrace is used, which might allow local users to trigger an out-of-bounds access to the system call table using the %RAX register and escalate privileges.
This module exploits a vulnerability caused due to a boundary error in the ierpplug.dll of the Real Player application. This module runs a malicious web site on the CORE IMPACT Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.
HP Linux Imaging and Printing exploit for Impact 7.5
A vulnerability has been identified in HP Linux Imaging and Printing System (HPLIP), which could be exploited by local attackers to obtain elevated privileges. This issue is caused by input validation errors in the hpssd daemon that does not validate user-supplied data before being passed to a popen3() call, which could be exploited by malicious users to inject and execute arbitrary commands with root privileges.
This package include local and remote versions of the exploit.

There is a buffer overflow in lasr.dll when parsing an AMI Pro document(.sam) file. The unsafe lstrcpy() function is used to copy each line read from the file into fixed sized stack and heap buffers, with no length checks being performed. Hence, it is possible to create an AMI Pro file that contains overly long lines that will trigger the buffer overflow when viewed within Lotus Notes.
In order to exploit this vulnerability successfully, the user must be convinced to view a malicious AMI Pro document file attachment using the built-in viewer in Lotus Notes.
Microsoft Visual Basic VBP File Processing Buffer Overflow Exploit
This module exploits a vulnerability in Visual Basic 6 .vbp files. The vulnerability is caused due to boundary error in VB6.EXE within the processing of VBP archives. This can be exploited to cause a stack-based buffer overflow when a specially crafted file is opened.
This module exploits a vulnerability caused due to a boundary error in the ierpplug.dll of the Real Player application. This module runs a malicious web site on the CORE IMPACT Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.
Windows Macrovision (SECDRV.SYS) Memory Corruption Exploit Update
This module exploits a vulnerability in Windows XP and Windows 2003 when the 0xCA002813 function is invoked with a specially crafted parameter. The IOCTL 0xCA002813 handler in the SECDRV.SYS device driver in Macrovision products, installed by default in Windows XP and Windows 2003, allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters.
This update corrects the CVE number and adds Windows 2003 as Supported System.
Windows Macrovision (SECDRV.SYS) Memory Corruption Exploit
This module exploits a vulnerability in Windows XP when the 0xCA002813 function is invoked with a specially crafted parameter. The IOCTL 0xCA002813 handler in the SECDRV.SYS device driver in Macrovision products, installed by default in Windows XP and Windows 2003, allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters.
This module exploits a vulnerability caused due to a boundary error in the Microsoft Agent ActiveX control (agentdpv.dll) when handling specially crafted URLs passed as argument to a certain unspecified method.
This package improves the reliability of the exploit.
