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.

The specific flaw exists within the implementation of the 0x138bd IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this functionality to execute code under the context of Administrator.
AVEVA InduSoft Web Studio Remote Command Execution Exploit
The MTCheckFileFunctionsTimeout function in UniSoft.dll does not check the user-supplied executable file name that is used to create a process. If the file name is already a full path, it will be passed as the lpCommandLine parameter to a CreateProcessW call.
Cisco Webex Meetings webexservice Update Service Local Privilege Escalation Exploit
A vulnerability in the update service of Cisco Webex Meetings Desktop App for Windows could allow an authenticated local attacker, to execute arbitrary commands with SYSTEM user privileges.
Microsoft Windows Shell Remote Code Execution Vulnerability Exploit (CVE-2018-8414)
Microsoft Windows Shell does not properly validate file paths, allowing the execution of ".SettingContent-ms" files from outside the "ImmersiveControlPanel" folder.
A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system.
The specific flaw exists within the handling of DPB files. When parsing the wKPFString attribute, the process does not properly validate the length of user-supplied data.
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.
Fortinet FortiClient IOCTL 220028 Local Privilege Escalation Exploit
The Fortishield.sys driver in Fortinet FortiClient before 5.2.4 allows local users to execute arbitrary code with kernel privileges by setting the callback function in a (1) 0x220024 or (2) 0x220028 ioctl call.
Easy File Sharing Web Server POST UserID Cookie Buffer Overflow Exploit
Stack-based buffer overflow in Easy File Sharing (EFS) Web Server 7.2 allows remote attackers to execute arbitrary code via a malicious login request to forum.ghp
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.
The specific flaw exists within the handling of HSC files. When parsing the IndirectAddrR attribute, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of Administrator.
D-Link Central WiFiManager FTP Server Default Credentials Remote PHP File Upload Vulnerability Exploit Update
D-Link Central WiFiManager has an FTP server listening on port 9000 by default with fixed credentials. This allows to unauthenticated users to upload and execute PHP files in the web root, leading to remote code execution.

D-Link Central WiFiManager FTP Server Default Credentials Remote PHP File Upload Vulnerability Exploit
D-Link Central WiFiManager has an FTP server listening on port 9000 by default with fixed credentials. This allows to unauthenticated users to upload and execute PHP files in the web root, leading to remote code execution.
The specific flaw exists within the dbman service, which listens on TCP port 2810 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute arbitrary code under the context of SYSTEM.
The specific flaw exists within the processing of a TLF file. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer.
