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.

This module exploits a JNDI injection present in the log4j library. The deployed agent will run with the root user account privileges on Linux systems and with SYSTEM privileges on Windows systems.
This module exploits a JNDI injection present in the log4j library. The deployed agent will run with the same privileges than the user account that ran Solr Server. This exploit will fail if the target system has jdk8u191 or newer.
Exploits / OS Command Injection / Known Vulnerabilities
Impact
Linux Kernel Dirty Pipe Local Privilege Escalation Exploit
Improper initialization of the flags member of the pipe buffer structure in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel, could allow an unprivileged local user to write to pages in the page cache backed by read-only files and escalate privileges on the system. This module creates a new pipe buffer with the PIPE_BUF_FLAG_CAN_MERGE flag which controls coalescing of writes into a pipe buffer and thus allows for writing to an existing page spliced into the pipe.
Apache James Log4shell Remote Code Execution Vulnerability Exploit
This module exploits a JNDI injection present in the log4j library. The deployed agent will run with the root user account privileges on Linux systems and with the same privileges than the user account that ran Apache James on Windows systems. This exploit will fail if the target system has jdk11.0.1 or newer.
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.
Grafana getPluginAssets Path Traversal Local File Disclosure Exploit
This module exploits a path traversal vulnerability present in the getPluginAssets function of Grafana which allows an attacker to download system files through specially crafted HTTP resource requests.
VMware vCenter Server Log4shell Remote Code Execution Vulnerability Exploit
This module exploits a JNDI injection present in the log4j library. The deployed agent will run with the root user account privileges on Linux systems and with SYSTEM privileges on Windows systems.
Microsoft Exchange TypedBinaryFormatter Deserialization Remote Code Execution Vulnerability Exploit
This module exploits a deserialization vulnerability present in the TypedBinaryFormatter class. The deployed agent will run with the SYSTEM privileges.
This module exploits a OGNL injection vulnerability present in the WebWork component of Atlassian Confluence. The deployed agent will run with tomcat privileges.
Microsoft Exchange MeetingPollHandler Deserialization Remote Code Execution Vulnerability Exploit
This module exploits a deserialization vulnerability present in MeetingPollHandler handler when using a ProposeOptionsMeetingPollParameters type. The deployed agent will run with the SYSTEM privileges.
VMware vCenter Server Virtual SAN Health Check plug-in Remote OS Command Injection Exploit
This module exploits a Java unsafe reflection and a Server Side Request Forgery vulnerabilities present in ProxygenController class via POST requests to the /ui/h5-vsan/rest/proxy/service endpoint. The deployed agent will run with the vsphere-ui user account privileges.
Cisco HyperFlex Data Platform Installer Command Injection Vulnerability Exploit
This module exploits a command injection vulnerability present in the main_checkHash function of the /opt/springpath/auth/auth service. The deployed agent will run with root privileges.
Apache HTTP Server Path Traversal Bypass File Disclosure Exploit
This module exploits a path traversal vulnerability in Apache Server which allows an attacker to download system files through specially crafted HTTP resource requests. This vulnerability is a bypass of CVE-2021-41773.
Microsoft Exchange Proxyshell Remote Code Execution Vulnerability Exploit
This module uses a path confusion that leads to an authentication bypass (ACL) which allows unauthenticated access to an arbitrary backend URL. Then an elevation of privilege present in CommonAccessTokenFromUrl of RemotePowershellBackendCmdletProxyModule.cs is used to execute Exchange powershell commands as Exchange Administrator. Finally, an arbitrary file write present in the New-MailboxExportRequest Exchange powershell command is used to write a webshell in the system file. The deployed agent will run with the SYSTEM privileges.
Apache HTTP Server Path Traversal Exploit (CVE-2021-41773)
This module exploits a path traversal vulnerability in Apache Server which allows an 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 (ports 5986, 5985 and 1270).
This module uses a reverse proxy bypass vulnerability to access restricted endpoints as declared in the analytics-proxy.conf file. Also, it uses an unauthenticated file upload vulnerability present in the DataAppAgentController class, when using the action=collect parameter. The deployed agent will run with root privileges.
This module exploits a vulnerability in Microsoft MSHTML, which can be leveraged to execute arbitrary code on vulnerable machines by convincing an unsuspecting user to visit a malicious web site.
The MODAPI.sys driver in MSI Dragon Center 2.0.104.0 exposes functionality that allows low-privileged users to write an arbitrary value to a Model-Specific Register (MSR) at the specified address via specially crafted IOCTL requests.
