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.

NVIDIA Windows GPU Display Driver R340 before 342.00 and R375 before 375.63 contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x600000D where a value passed from a user to the driver is used without validation leading to escalation of privileges.
HPE Intelligent Management Center is prone to a remote vulnerability that allows attackers to take advantage of an insecure deployment of the RMI Registry service used to manage and monitor the Java Virtual Machine.
Microsoft Visual Basic VBP File Processing Buffer Overflow Exploit
This module exploits a vulnerability in Visual Basic 6 .vbp files. The vulnerability is caused due to boundary error in VB6.EXE within the processing of VBP archives. This can be exploited to cause a stack-based buffer overflow when a specially crafted file is opened.
This module exploits a integer overflow vulnerability in the xpdf and libpoppler software included in most linux distributions. The vulnerability is caused by a integer overflow in the predictor calculation, which causes a buffer overflow in the stack of the StreamPredictor::getNextLine() function. The exploit is triggered when an unsuspecting user opens a specially crafted file distributed via an email.
Viscosity for Windows suffers from a privilege escalation vulnerability. By abusing the named pipe configuration channel between the client and the underlying service, a local attacker can gain SYSTEM privileges.
This module exploits a vulnerability in the kwedit.dll control included in the EnjoySAP application. The exploit is triggered when the PrepareToPostHTML() method processes a long string argument resulting in a stack-based buffer overflow. This module runs a malicious web site on the CORE IMPACT Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.
The RMI service in SolarWinds Virtualization Manager 6.3.1 and earlier allows remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the Apache Commons Collections (ACC) library.
Hewlett Packard Enterprise Data Protector EXEC_BAR User Name Buffer Overflow Exploit
The specific flaw exists within OmniInet.exe which listens by default on TCP port 5555. When parsing a malformed user name field in a request, the process blindly copies user supplied data into a fixed-length stack buffer. A remote attacker can abuse this to execute remote code under the context of SYSTEM.
The specific flaw exists within the activate_doit function of the service. The issue lies in the handling of the server parameter which can result in overflowing a stack-based buffer.
This update introduces more accurate information about vulnerable targets.
Microsoft Exchange Validation Key Remote OS Command Injection Exploit Update Improvements
.NET deserialization vulnerability in the Microsoft Exchange Control Panel web page allows authenticated attackers to execute OS commands with SYSTEM privileges.
The lack of randomization in the validationKey and decryptionKey values at installation allows an attacker to create a crafted viewstate to execute OS commands via .NET deserialization.

Microsoft Internet Explorer HTML Object Memory Corruption Exploit (MS10-002)
This module exploits a use-after-free vulnerability in the MSHTML component in Internet Explorer. The specific error ocurrs due to the way Internet Explorer handles objects in memory. It is possible to use a pointer in CTableRowCellsCollectionCacheItem::GetNext after it gets freed and get remote code execution.
This vulnerability was one of the 2012's Pwn2Own challenges.
This module exploits a vulnerability in McAfee Virtual Technician MVTControl, which can be abused by using the GetObject() function to load unsafe classes, therefore allowing remote code execution under the context of the user.
Microsoft SharePoint Server WikiContentWebpart Web Part Remote OS Command Injection Exploit (CVE-2020-1181)
A remote code execution vulnerability exists in Microsoft SharePoint Server when it fails to properly identify and filter unsafe ASP.Net web controls, aka 'Microsoft SharePoint Server Remote Code Execution Vulnerability'.
This update includes a module that executes a program designed to test a buffer overflow in glibc's __nss_hostname_digits_dots function. The function is used by the gethostbyname*() functions family used for name resolution. Under some circumstances, the use of those functions when the vulnerable underlying function is present, may lead to remote code execution, privilege escalation, or information disclosure.
Untrusted search path vulnerability in Corel Painter 2015 14.0.0.728 and earlier, and possibly other versions allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse wacommt.dll that is located in the same folder as an .rif file.
