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.

Path traversal vulnerability in WinRAR when crafting the filename field of the ACE format (in UNACEV2.dll). When the filename field is manipulated with specific patterns, the destination (extraction) folder is ignored, thus treating the filename as an absolute path.
A critical vulnerability, identified and cataloged as CVE-2023-38831, has been discovered. This vulnerability allows attackers to create modified RAR or ZIP archives that contain both harmless files and malicious ones. The malicious files are typically scripts located within a folder that shares the same name as the harmless file.
The file names showed in WinRAR when opening a ZIP file come from the central directory, but the file names used to extract and open contents come from the Local File Header. This allows to spoof file names when opening ZIP files and can be abused to execute arbitrary code.

WinRAR LHA-LZH exploit
This module exploits a stack buffer overflow in WinRAR 3.60 beta6 and prior to install a level0 agent.
This module exploits a stack buffer overflow in WinRAR 3.60 beta6 and prior to install a level0 agent. This update adds support to register the exploit into the IMPACT webserver.
This module exploits a vulnerability in the FileView ActiveX control installed by WinZip v10.0 series prior to build 7245, and will install a Level0 agent.
The DRDA protocol dissector in Wireshark can enter an infinite loop when processing an specially crafted DRDA packet with the iLength field set to 0, causing Wireshark to stop responding.
This module exploits a stack-based buffer overflow in the WireShark LWRES dissector by sending a specially crafted LWRES packet. This update adds support for more WireShark versions.
This module exploits a vulnerability in the WireShark openSAFETY dissector, sending a specially crafted openSAFETY packet over UDP, causing WireShark to crash.
A heap-based buffer overflow was found in the DECT dissector of Wireshark. A remote attacker could use this flaw to cause the Wireshark executable to crash or potentially to execute arbitrary code with the privileges of the user running Wireshark.
This module exploits a stack buffer overflow in Wireshark when opening a crafted .PCAP file, resulting in arbitrary code execution. This module bypass DEP using ROP techniques.
Wireshark PROFINET Dissector Format String Exploit
Wireshark is prone to a format-string vulnerability. Attackers can leverage this issue to execute arbitrary code within the context of the vulnerable application. Failed attacks will likely cause denial-of-service conditions.
Wireshark PROFINET Dissector Format String Exploit Update
Wireshark is prone to a format-string vulnerability. Attackers can leverage this issue to execute arbitrary code within the context of the vulnerable application. Failed attacks will likely cause denial-of-service conditions. This update adds windows 7 support.
