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.

Adobe ColdFusion is prone to a remote vulnerability that allows attackers to take advantage of an insecure deployment of the JMX/RMI service used to manage and monitor the Java Virtual Machine.
Lepide Auditor Suite createdb Web Console Database Injection Remote Code Execution Vulnerability Exploit
The application allows an attacker to specify a server to perform authentication. That server also allows to execute controlled SQL directly against the database. This module abuses of the previous vulnerabilities in order execute an agent as SYSTEM.

Linux Kernel UFO Memory Corruption Privilege Escalation Exploit
This module exploits a memory corruption vulnerability in the Linux kernel. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption that can be used by an attacker to escalate privileges.
Apache Tomcat allows the upload of JSP files to unauthenticated users via a specially crafted request when the readonly initialization parameter of the Default servlet is set to false.
Microsoft NET Framework SOAP WSDL Parser Code Injection CVE-2017-8759
This module exploits a vulnerability in Microsoft Office Word. The flaw is related in how Microsoft Word parses SOAP WSDL links. It is possible to open a RTF file and execute arbitrary code in vulnerable installations of Microsoft Office Word.
Fuji Electric Monitouch V-SFT Project File Buffer Overflow Exploit
Fuji Electric Monitouch is prone to a buffer-overflow vulnerability that occurs because it fails to perform adequate boundary checks on user-supplied data via a crafted.v8 document. This module runs a malicious web server on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
A heap overflow in the ActiveX control nvA1Media.ocx in Advantech WebAccess allows remote attackers to execute arbitrary code via a crafted argument to the Caption method. This module runs a web server waiting for vulnerable clients (Internet Explorer 6, 7 or 8) to connect to it. When the client connects, it will try to install an agent by exploiting this vulnerability.

Eaton ELCSoft EPC File Buffer Overflow Exploit
Eaton ELCSoft is prone to a heap-overflow vulnerability that occurs because it fails to perform adequate boundary checks on user-supplied data via a crafted .EPC document. This module runs a malicious web server on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
RAT Gh0st Controller Server Buffer Overflow Exploit
A vulnerability exists in the way RAT Gh0st Controller Server process a remote request. The vulnerability is caused due to a boundary when handling network messages and can be exploited to cause a buffer overflow via a specially crafted packet sent to the server.
The specific flaw exists within the parsing of a pm3 project file. A heap-based buffer overflow vulnerability exists in a call to memcpy. An attacker can leverage this vulnerability to execute arbitrary code in the context of the process. This module runs a malicious web server on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
Microsoft Windows LNK Shortcut Automatic File Execution Exploit (CVE-2017-8464)
Microsoft Windows is prone to a vulnerability that may allow a file to automatically run because the software fails to handle 'LNK' files properly. Specifically, the issue occurs when loading the icon of a shortcut file. A specially crafted 'LNK' file can cause Windows to automatically execute code that is specified by the shortcut file. The attacker must entice a victim into viewing a specially crafted shortcut. The shortcut file and the associated binary may be delivered to a user through removable drives, over network shares or remote WebDAV shares.
Fuji Electric V Server VPR File Parsing Memory Corruption Exploit
Fuji Electric V Server is prone to a buffer-overflow vulnerability that occurs because it fails to perform adequate boundary checks on user-supplied data via a crafted .VPR document. This module runs a malicious web server on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
Mitsubishi Electric E-Designer BEComliSlave Driver Configuration Status_bit Buffer Overflow Exploit
Buffer Overflow in Mitsubishi Electric E-Designer allows remote attackers to execute arbitrary code via crafted MPA file, leading to improper memory allocation.
Nitro Pro PDF Reader Javascript API Remote Code Execution Exploit
Unsafe Javascript API implementation in Nitro and Nitro Pro PDF Reader when opening specially crafted PDF files makes possible code execution leading to an agent being installed This module runs a malicious web server on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
Linux Kernel packet_set_ring Privilege Escalation Exploit
This module exploits a signedness error condition in the Linux Kernel via PACKET_RX_RING option on an AF_PACKET socket with a TPACKET_V3 ring buffer version enabled. The packet_set_ring function in net/packet/af_packet.c in the Linux kernel through 4.10.6 does not properly validate certain block-size data, which allows local users to escalate privileges.
Linux Kernel DCCP_PKT_REQUEST Privilege Escalation Exploit
This module exploits a double-free vulnerability in the Linux Kernel. The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to escalate privileges via an application that makes an IPV6_RECVPKTINFO setsockopt system call.
