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.

Microsoft Windows Kernel AuthzBasepCopyoutInternalSecurityAttributes Elevation of Privilege Vulnerability Exploit
The Windows NT operating system kernel executable (ntoskrnl.exe) present in Microsoft Windows is vulnerable to a race condition, which can result in arbitrary memory write. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges.
Linux Kernel GSM Multiplexing Race Condition Local Privilege Escalation Exploit
This vulnerability allows local attackers to execute arbitrary code on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the n_gsm driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel.
SolarWinds Serv-U FTP Server Path Traversal Vulnerability Exploit
A directory traversal vulnerability in SolarWinds Serv-U FTP Server allows unauthenticated remote attackers to download system files. To take advantage of this vulnerability, we need to make a request using the InternalDir and InternalFile parameters, this will allow us to trigger a directory traversal and thus be able to read an arbitrary file. This module exploits the directory traversal to download the file specified and to save it locally in the location specified in the "OUTPUT PATH" parameter.
Ivanti Core Server EPM Remote Code Execution Exploit
A vulnerability in the RecordGoodApp method allows to unauthenticated remote attackers to execute commands. This function is potentially vulnerable to an SQL injection because it uses string.Format to insert a value into the SQL query.
A SQL injection vulnerability in Fortra FileCatalyst Workflow versions 5.1.6 build 135 and earlier allows remote attackers, including anonymous ones, to exploit a SQL injection via the JOBID parameter. This could lead to unauthorized SQL commands execution such as table deletion or admin user creation. This module without authentication creates an administrative user, proceeds to authenticate with this newly created user to assess if the system is vulnerable. This module does not install an agent but instead creates an administrator user for FileCatalyst.s
Progress Telerik Report Server XmlSerializer NET Deserialization Vulnerability Remote Code Execution Exploit
This module chains 2 vulnerabilities to deploy an agent in Progress Telerik Report Server that will run with root user privileges. The first vulnerability is an authentication bypass vulnerability present in Telerik.ReportServer.Web.Controllers.StartupController.Register class. The second vulnerability a .NET deserialization vulnerability in Telerik.Reporting.XmlSerialization.XmlSerializer class. This module will use first vulnerability to create a random user with "System Administrator" role against the "/Startup/Register" endpoint and then login into the application.

Ivanti Connect Secure WEB COMPONENT Unauthenticated Remote Code Execution Exploit
An authenticated user can exploit a command injection vulnerability in the web components of Ivanti Connect Secure (9.x and 22.x) to execute arbitrary commands. This module exploits two vulnerabilities. First, it leverages the lack of authentication in "/api/v1/totp/user-backup-code", allowing unauthenticated access and path traversal. Then, it uses this vulnerability to access the system and execute remote commands in "/api/v1/license/key-status/path:node_name". The deployed agent will run with ROOT privileges.
Microsoft Windows CSC Service Elevation of Privilege Vulnerability Exploit
The Windows Client Side Caching Driver (csc.sys) present in Microsoft Windows is vulnerable to a memory corruption vulnerability. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges by creating a specially crafted IOCTL request.
Microsoft Windows InitializeXamlDiagnosticsEx Local Privilege Escalation Exploit
This exploit uses InitializeXamlDiagnosticsEx in order to inject a DLL in an elevated process. It will check if any elevated process running uses UWP and then inject. One example of elevated process with UWP is taskmgr. It will check for 180 seconds.
An error in the way Fortra Robot Schedule grants write permission to unprivileged users to replace modules that are running with system privileges. A low-privileged user can overwrite the service executable. When the service is restarted, the replaced binary runs a SYSTEM privileged Core Impact agent.
In PHP, when using Apache and PHP-CGI on Windows and if the system is set up to use certain code pages, Windows may use "Best-Fit" behavior to replace characters in command line given to Win32 API functions. PHP CGI module may misinterpret those characters as PHP options, which may allow remote attackers to pass options to PHP binary being run, leading to execute system commands in the context of the affected application.
