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.

phpMyAdmin is vulnerable to a remote code execution due the use of the unserialize method on user supplied data. This data is written in the config file and is accessible from the internet by default.
Input passed via the URL is not properly sanitised before being returned to the user within the search.php, sendmessage.php, showgroups.php, usercp.php, online.php, misc.php, memberlist.php, member.php, index.php, forumdisplay.php, inlinemod.php, newthread.php, private.php, profile.php, register.php, showthread.php, subscription.php, forum.php, faq.php, and calendar.php script. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
This module exploits a vulnerability in the AeXNSConsoleUtilities.dll control included in the Symantec ConsoleUtilities application. The vulnerability is triggered when the RunCmd method processes a long string argument resulting in a stack-based buffer overflow.
This module exploits a stack overflow in library DCCFAXVW.DLL of Symantec WinFax Pro. When passing an overly long string to the AppendFax() method, arbitrary code may be executed.
Microsoft Windows Ws2ifsl UaF Local Privilege Escalation Exploit
An elevation of privilege vulnerability exists in the way that ws2ifsl.sys (Winsock) handles objects in memory, aka 'Windows Elevation of Privilege Vulnerability'
Multiple ACDSee products are prone to a buffer-overflow vulnerability because they fail to perform adequate boundary checks when processing a malformed TIFF image.
This update adds support for older ACDSee versions.
GlobalSCAPE Secure FTP Server Remote Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on installations with GlobalSCAPE Secure FTP Server,which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error with the handling of overly long commands. This can be exploited to cause a stack-based buffer overflow via an overly long, specially-crafted command passed to the affected server.

Microsoft Works wkimgsrv.dll Memory Corruption Exploit
This module exploits a vulnerability in the wkimgsrv.dll control shipped with Microsoft Works and many Microsoft Office Suites. The exploit is triggered when the WksPictureInterface() method processes a number as argument resulting in a memory corruption. The WksPictureInterface(), in certain circumstances, points to an invalid memory address that can be controlled to gain code execution.
This module exploits a buffer overflow vulnerability during the processing of TFTP Read/Write request packet types and cause a stack-based buffer overflow by sending a specially crafted packet with an overly long mode field.
Drupal RESTful Web Services Module Remote PHP Command Injection Exploit
RESTful Web Services Module does not properly sanitize data from non-form sources. A vulnerability in this approach allows an unauthenticated attacker to send specially crafted requests resulting in arbitrary PHP execution.
The vulnerability is caused due to a boundary error when parsing format strings containing a floating point specifier in the util.printf() JavaScript function.
This update improves exploit reliability and fixes a cookie handling bug.
ASUS Low Level Access Drivers Privilege Escalation Exploit
This module exploits a vulnerability in various ASUS and 3rd party branded utilities. The low level access drivers at the core of these utilities expose dangerous functionality to low privilege processes, a local attacker can read/write arbitrary kernel memory, which can be leveraged to elevate privileges.
BigAnt IM Server HTTP GET Request Remote Buffer Overflow Exploit
This module exploits a vulnerability in the AntServer Module (AntServer.exe), this can be exploited to cause a stack-based buffer overflow by sending a specially crafted, overly long HTTP GET request to default port 6080/TCP.
Fuji Electric V-Server VPR File Parsing Buffer Overflow Exploit (CVE-2018-10637)
The specific flaw exists within the processing of VPR files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a buffer.
This module exploits a vulnerability in various ASROCK utilities. The low level access drivers at the core of these utilities expose dangerous functionality to low privilege processes, a local attacker can read/write arbitrary kernel memory, which can be leveraged to elevate privileges.
Kingsoft Internet Security Local Privilege Escalation Exploit
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Kingsoft Internet Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaws exists within the processing of IOCTL 0x80030004 or 0x80030008 by the KWatch3.sys (internet security) kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in a kernel stack buffer overflow.
This module exploits a vulnerability in the InstallShield Update Service ActiveX control (isusweb.dll) in MacroVision FLEXnet Connect and InstallShield 2008.
