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.

Cisco Prime Infrastructure Java Object Deserialization Remote Code Execution Exploit
Cisco Prime Infrastructure 1.2.0 through 2.2(2) and Cisco Evolved Programmable Network Manager (EPNM) 1.2 allow remote attackers to execute arbitrary code via crafted deserialized data in an HTTP POST request, aka Bug ID CSCuw03192.
OpenNMS Platform 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.
The specific flaw exists within the RA.ViewElements.Row.1 ActiveXControl method (PanelDevice.dll). By providing a malicious value to the BackColor property.

Schneider Electric SoMachine HVAC AxEditGrid ActiveX Exploit
The specific flaw exists within the SetDataIntf method of the AxEditGrid control. The control has an untrusted pointer dereference vulnerability because it blindly calls an attacker-supplied memory address.
phpMyAdmin is prone to a regexp abuse via an eval modifier which can be found in old PHP versions. This vulnerability allows authenticated attackers to run arbitrary php code on the affected server.
PHP versions 4.3.0-5.4.6 had a "feature" which allowed users to run a RegExp Pattern Modifier using PREG_REPLACE_EVAL and may lead to execute code.
phpMyAdmin had an issue in their code that can be exploited from a table replace call.
The general idea is to insert a crafted regexp eval record format, and then trigger it via a find and replace function with system commands

WebNMS Framework Server Arbitrary File Upload Vulnerability Exploit
A vulnerability exists in the FileUploadServlet servlet of WebNMS Framework Server. This servlet allows unauthenticated file uploads. By uploading a JSP file, an attacker can achieve remote code execution.
JMS Object messages within Apache ActiveMQ depend on Java Serialization for marshaling/unmashaling of the message payload. This lead to execution of untrusted code when a specially crafted object is received.
This update introduces an exploit that will attempt to connect using the STOMP protocol and abuse the vulnerability to execute a Core Impact agent in the vulnerable system.
Microsoft Windows CreateSizedDIBSECTION Thumbnail View Buffer Overflow Exploit Update
Microsoft Windows is prone to a stack-based buffer-overflow vulnerability in the Windows Graphics Rendering Engine because the software fails to perform adequate boundary-checks on user-supplied data.
WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations. Since this module is not the final version it may contain bugs or have limited functionality and may not have complete or accurate documentation.
IBM Lotus Quickr For Domino qp2 ActiveX Control Heap Overflow Exploit Update
A heap overflow in the ActiveX control qp2.cab in IBM Lotus Quickr for Domino allows remote attackers to execute arbitrary code via a crafted argument to the Attachment_Names method.
This update reduces user interaction, automating the focus of the mouse in the created window object.
Microsoft Windows MRXDAV.SYS WebDav Privilege Escalation Exploit (MS16-016)
This module exploits a vulnerability in Microsoft Windows MRXDAV.SYS driver. This vulnerability allows a local attacker to execute arbitrary code with SYSTEM privileges in a vulnerable target.
Linux Kernel netfilter target_offset Privilege Escalation Exploit
This module exploits a vulnerability in the Linux kernel related to the netfilter target_offset field. This vulnerability can be exploited by a local unprivileged attacker to gain root privileges.
Microsoft Internet Explorer Typed Array Detached ArrayBuffer Use-After-Free Exploit (MS16-063)
Internet Explorer is prone to a use-after-free vulnerability when trying to access the ArrayBuffer that was backing a Typed Array after it has been detached by transferring it to a Web Worker by calling the postMessage() function.
This vulnerability can be abused by an attacker to execute arbitrary code on systems running vulnerable versions of Internet Explorer.
Action Pack in Ruby on Rails allows remote attackers to execute arbitrary Ruby code by leveraging an application's unrestricted use of the render method.
JBoss Application Server is prone to a remote vulnerability due to deserialization of untrusted inputs, allowing attackers to instantiate arbitrary java objects leading to remote code execution.
This vulnerability affects the EJBInvokerServlet component of the server.
The vulnerability resides in parsing crafted Microsoft PowerPoint documents and produces a buffer overflow in the stack, leading to a privilege escalation to System.
RESTWS alters the default page callbacks for entities to provide additional functionality. A vulnerability in this approach allows an unauthenticated attacker to send specially crafted requests resulting in arbitrary PHP execution.
Incorrect signedness comparison in the ioctl handler of the atkbd keyboard driver in the FreeBSD kernel can be leveraged by a local unprivileged user to overwrite a portion of the kernel memory, thus allowing the attacker to gain root privileges on the affected system.
This update improves the checking of preconditions before launching the attack.
