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.

Post Exploitation
Impact
VMware vCenter Server Log4shell Remote Code Execution Vulnerability Exploit Update
Win32k Window Object Type Confusion Local Privilege Escalation
The vulnerability is a win32k window object type confusion leading to an OOB (out-of-bounds) write which can be used to create arbitrary memory read and write capabilities within the Windows kernel to achieve elevated privileges.
PolicyKit pkexec Elevation of Privilege Vulnerability Exploit
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code.
This module allow to set a short name 8.3 of a file when you don't have write privileges to the directory where the file is located.The vulnerability exists due to NtfsSetShortNameInfo does not properly impose security restrictions in NTFS Set Short Name, which leads to security restrictions bypass and privilege escalation.
Grafana getPluginAssets Path Traversal Local File Disclosure Exploit
A path traversal vulnerability in Grafana may allow an unauthenticated attacker to download system files through specially crafted HTTP resource requests.
VMware vCenter Server Log4shell Remote Code Execution Vulnerability Exploit
JNDI features used in configuration, log messages, and parameters present in Apache Log4j2 do not protect against attacker controlled LDAP and other JNDI related endpoints. This library, used by VMware vCenter Server, allows unauthenticated attackers to execute system commands.
JNDI features used in configuration, log messages, and parameters present in Apache Log4j2 do not protect against attacker controlled LDAP and other JNDI related endpoints. This library, used by VMware vRealize Operations Manager, allows unauthenticated attackers to execute system commands.
Microsoft Exchange TypedBinaryFormatter Deserialization Remote Code Execution Vulnerability Exploit
A deserialization vulnerability present in the TypedBinaryFormatter class allows authenticated remote attackers to execute arbitrary OS commands with SYSTEM user privileges.
Linux Kernel Netfilter Xt Compat Target From User Local Privilege Escalation Exploit
A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space.
An OGNL injection vulnerability in Confluence Server and Data Center allow an unauthenticated attacker to execute arbitrary code on a Confluence Server or Data Center instance.
Canon Printer TR150 Driver Local Privilege Escalation Exploit
The Canon TR150 print driver is vulnerable to a privilege escalation issue. During the add printer process an attacker can overwrite a DLL and, if timed properly, the overwritten DLL will be loaded into a SYSTEM process resulting in escalation of privileges.
Cisco HyperFlex Data Platform Installer Command Injection Vulnerability Exploit
The password input field in the "/auth/" and "/auth/change" endpoints of Cisco HyperFlex HX Installer Virtual Machine allow an unauthenticated attacker to execute systems commands as root.
Apache HTTP Server Path Traversal Bypass File Disclosure Exploit
A path traversal vulnerability in Apache HTTP server may allow an unauthenticated attacker to download system files through specially crafted HTTP resource requests.
Microsoft Exchange Proxyshell Remote Code Execution Vulnerability Exploit
A combination of a path confusion that leads to an authentication bypass (ACL), an elevation of privilege and an arbitrary file write vulnerability, allows unauthenticated attackers to execute commands with SYSTEM privileges in Microsoft Exchange Server.
Microsoft Windows win32kbase Use After Free MisterySnail NtGdiResetDC Privileged Escalation Exploit
CVE-2021-40449 is a use-after-free vulnerability in Win32k's NtGdiResetDC function. As with many other Win32k vulnerabilities, the root cause of this vulnerability lies in the ability to set user-mode callbacks and execute unexpected API functions during execution of those callbacks. The CVE-2021-40449 is triggered when the function ResetDC is executed a second time for the same handle during execution of its own callback.
Microsoft MSHTML Remote Code Execution Exploit Update
This is a critical vulnerability in the MSHTML rendering engine. Microsoft Office applications use the MSHTML engine to process and display web content. An adversary who successfully exploits could achieve full control over a target system by using malicious ActiveX controls to execute arbitrary code.
This Update contains the following improvements:
-Default Connection method was changed to HTTPS
-Early Release Warning was removed
-Several "Application Name" in "Supported systems" property were added
Apache HTTP Server Path Traversal Exploit CVE-2021-41773
A path traversal vulnerability in Apache HTTP server may allow an unauthenticated attacker to download system files through specially crafted HTTP resource requests.
Open Management Infrastructure OMIGOD Remote Code Execution Exploit
A remote code execution vulnerability exists in OMI. An unauthenticated, remote attacker can exploit this flaw by sending a specially crafted request to a vulnerable service over a publicly accessible remote management port.
A reverse proxy bypass vulnerability allows attackers to access restricted endpoints as declared in the analytics-proxy.conf file.
Combined with a unrestricted file upload vulnerability present in the DataAppAgentController class, when using the action=collect parameter, allows attackers to execute systems commands as root.
This is a critical vulnerability in the MSHTML rendering engine. Microsoft Office applications use the MSHTML engine to process and display web content. An adversary who successfully exploits could achieve full control over a target system by using malicious ActiveX controls to execute arbitrary code.
