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.

A buffer overflow in the ScStoragePathFromUrl function in the WebDAV service in Internet Information Services (IIS) 6.0 in Microsoft Windows Server 2003 R2 allows remote attackers to execute arbitrary code via a long header in a PROPFIND request.
An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java object to the Jenkins CLI, making Jenkins connect to an attacker-controlled LDAP server, which in turn can send a serialized payload leading to code execution, bypassing existing protection mechanisms. This can be exploited by malicious local attackers to gain SYSTEM privileges on Windows targets.
The register method in the UsersModelRegistration class in controllers/user.php in the Users component in Joomla! before 3.6.4 allows remote attackers to gain privileges by leveraging incorrect use of unfiltered data when registering on a site. This registration works even when registration has been disabled. This module exploits this vulnerability to add an administrator user to the Joomla database. Notice that this account could need registration confirmation (activation).

Webex Extension Remote Code Execution Exploit
This module exploits a vulnerability in the WebEx extension for Chrome. The module will start a web server and serve a specially crafted page. The page will execute a series of PowerShell commands to download an executable file from Impact's web server and execute it. The vulnerability requires that the attack web page be served using HTTPS. See "Special comments" for futher detail.
Mozilla Firefox Use After Free DOM and Audio Elements Exploit
This module exploits a use after free vulnerability while manipulating DOM events and removing audio elements due to errors in the handling of node adoption in Mozilla Firefox. This module runs a web server waiting for vulnerable clients (Mozilla Firefox) to connect to it. When the client connects, it will try to install an agent by exploiting this vulnerability.
Microsoft Windows Win32k Privilege Escalation Exploit (MS16-135)
This module exploits a vulnerability in win32k.sys. By forcing an invalid combination of window style and window menu, a local attacker can trigger a kernel arbitrary right, resulting in elevated privileges.
Linux Kernel Dirty COW Race Condition Privilege Escalation Exploit
This module exploits a race condition vulnerability in the Linux Kernel via MAP_PRIVATE COW. The bug relies in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
This module exploits a vulnerability in Rivatuner's core (Rivatuner*.sys, RTCore*.sys), a driver used by hardware tweaking apps Rivatuner, MSI Afterburner, EVGA Precision X (and possibly others). During app operation, the driver is loaded and used to read and write physical memory, MSR registers, io ports, etc. This module abuses said functionality to escalate privileges.
