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
DHCP Server with Bash Variables Injection Exploit
This module runs a DHCP server. When requests (DHCPREQUEST or DHCPDISCOVER) are received, it will respond with an offer according to the given configuration, and it will include a string leveraging the GNU Bash Environment Variables Injection vulnerability into the DHCP's 'default-url' option to register a crond script, that'll subsequently download and execute an Impact agent, using the target system's wget. The injection will be tried once per MAC.
Adobe Flash Player ShaderJob Buffer Overflow Exploit
This module exploits a buffer overflow vulnerability in Adobe Flash Player. The specific flaw exists when the "width" attribute of a ShaderJob is modified after starting the job allowing to an attacker to control the size of a destination buffer and the length of the copy operation.
This module exploits a buffer overflow vulnerability in the LDAP service (nLDAP.exe) of the LDAP application. The exploit triggers a stack-based buffer overflow by sending a pre-authentication specially crafted packet to port 389/TCP of the vulnerable system and installs an agent if successful.
Linux Overlayfs Local Privilege Escalation Exploit
This module exploits a vulnerability in Linux. The overlayfs filesystem does not correctly check file permissions when creating new files in the upper filesystem directory. This can be exploited by an unprivileged process in kernels with CONFIG_USER_NS=y and where overlayfs has the FS_USERNS_MOUNT flag, which allows the mounting of overlayfs inside unprivileged mount namespaces.
Microsoft Windows Win32k Privilege Escalation Exploit(MS15-010)
An elevation of privilege vulnerability exists in the Windows kernel-mode driver (Win32k.sys) that is caused when it improperly handles objects in memory. A local unprivileged user who successfully exploited this vulnerability could execute arbitrary code with SYSTEM privileges. This module exploits the previous vulnerability to deploy an agent that runs with SYSTEM privileges.
Adobe Flash Player AS2 NetConnection Type Confusion Exploit
This module exploits a Type Confusion vulnerability in Adobe Flash Player. The specific flaw exist in the ActionScript 2 NetConnection class. When a NetConnection method is called with a parameter that is a native function object, its native data can be specified as a Number by the caller, but be interpreted as a pointer. This allows to overwrite different objects like vectors and finally accomplish remote code execution.
This module exploits a JPEG2000 vulnerability (CVE-2012-0897) in "vprintproxy.exe" through COM1 from the VMware guest operating system to the host operating system.
QEMU Floppy Disk Controller fdctrl_handle_drive_specification_command Virtual Machine Escape Exploit (VENOM)
The fdctrl_handle_drive_specification_command() function in the code that emulates the Floppy Disk Controller in QEMU does not properly reset the index within a buffer when processing user-controlled data, leading to a heap-based buffer overflow in the QEMU process that runs on the Host system. An attacker running code within a Guest operating system can exploit this vulnerability in order to escape from the QEMU virtual machine and execute arbitrary code on the Host operating system. This vulnerability is also known as VENOM.
OpenLDAP modrdn Request Multiple Vulnerabilities DoS
This module exploits a null pointer vulnerability in the OpenLDAP service when parsing a malformed requests. The vulnerability is exploited remotely by sending a specially crafted packet to write an existing value with an empty one. The service will be automatically restarted after 1-2 minutes. To keep the service down set KEEP_TRYING parameter true
This module sends HTTP requests with specially crafted data making the PHP process consume lot of resources. This attack prevents the victim server from processing requests from legitimate clients and probably will make the server non-operational. The PATH parameter must point to a PHP web page, which they normally have a ".php" extension.
A buffer overflow vulnerability exists in Microsoft's PPTP (Point to Point Tunnelling Protocol) implementation. Both the PPTP server and client applications are vulnerable. It is possible to crash the kernel of the target (blue screen), the installation of an agent using this vulnerability is difficult and have not been implemented in this module.
This module exploits a memory corruption vulnerability in the Serva32 HTTP Server by sending a malformed packet to the 80/TCP port to crash the application.

Serva TFTPD Service Large Read Requests Parsing DoS
The Serva32 TFTPD service is vulnerable to a buffer overflow vulnerability when parsing large read requests. When the application reads in a large buffer the application crashes
By sending a specially crafted SMB packet, this exploit performs a Denial of Service attack on the target machine. The attack will trigger an operating system halt (Blue Screen).

This module shuts down the Solar FTP Server(sfsservice.exe)because it fails to properly handle user-supplied commands.

Squid Web Proxy Cache HTTP Version Number DoS
A parsing error when parsing the HTTP version causes a Squid cache process to terminate. This module sends HTTP requests that exploits this vulnerability. After repeating this several times the Squid cache stops and it doesn't restart.
Multiple vulnerabilities have been identified in Sun Java System Web Server, which could be exploited by remote attackers to cause a denial of service or compromise a vulnerable system. These issues are caused by buffer overflow errors when processing malformed "TRACE" or "OPTIONS" requests, or overly long "Authorization: Digest" headers, which could be exploited by attackers to crash an affected server or execute arbitrary code. This exploit forces the server process to throw an unhandled exception and be restarted.
This module exploits a vulnerability in Symantec AMS Intel Handler service by sending a malformed packet to the 38292/TCP port to crash the application.
