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.

Evological EvoCam Remote Buffer Overflow Exploit
The vulnerability is caused due to a boundary error in the included web server when processing HTTP requests. This can be exploited to cause a stack-based buffer overflow via an overly long GET request.
This module uploads a specially crafted e-mail via a user provided IMAPv4 account and waits until this email is opened through OWA (Outlook Web Access) and any button inside the window is pressed (the Maximize/Normal, Minimize and Close buttons do nothing), then the agent connects back.
The Internet Mail Service in Exchange Server 5.5 and Exchange 2000 allows remote attackers to cause a denial of service (memory exhaustion) by directly connecting to the SMTP service and sending a certain extended verb request (XEXCH50) In Exchange 2000 an agent could be installed exploiting a buffer overflow in the same SMTP command.
Heap based buffer overflow handling the X-LINK2STATE command in the SMTP service of Exchange Server allows the execution of arbitrary code. After successful exploitation an agent will be installed.
This module is a port to Python of the Metasploit module developed by Qualys for CVE-2015-0235. This module remotely exploits CVE-2015-0235 (a.k.a. GHOST, a heap-based buffer overflow in the GNU C Library's gethostbyname functions) on x86 and x86_64 GNU/Linux systems that run the Exim mail server. Technical information about the exploitation can be found in the original GHOST advisory, and in the source code of this module. SERVER-SIDE REQUIREMENTS (Exim) Summary: if this module's "check" or "exploit" method determines that a remote system is vulnerable, it is probably also exploitable.
The internal string handling functions of the Exim software contain a function called string_format(). The version of this function included with Exim versions prior to 4.70 contains a flaw that can result in a buffer overflow. This module exploits the vulnerability to run commands as the "Debian-exim" user. Afterwards, this module attempts to exploit the Alternate Configuration Privilege Escalation Vulnerability (CVE-2010-4345). If the second exploit is successful, an agent is installed with root privileges.

FileCopa LIST Command Remote Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on installations of FileCopa FTP Server, which can be exploited by malicious people to compromise a vulnerable system. FileCopa FTP Server is prone to a buffer-overflow vulnerability when handling data through the LIST command, a large amount of data can trigger an overflow in a finite-sized internal memory buffer. Successful login in the ftp server is required to exploit this vulnerability. Anonymous user is enabled by default.
File Sharing Wizard HEAD Command Buffer Overflow Exploit
An internal memory buffer may be overrun while handling "HEAD" command. This condition may be exploited by attackers to ultimately execute instructions with the privileges of the FileSharingWizard.exe process.
This module exploits a buffer overflow vulnerability in the database service (fbserver.exe) of the FireBird SQL application. The exploit triggers a stack-based buffer overflow by sending a specially crafted "create" request to port 3050/TCP of the vulnerable system and installs an agent if successful.

A vulnerability in the freeSSHd SSH Server allows remote attackers to bypass authentication via a crafted session. This module exploits the vulnerability and installs an agent into the target host.
Free Download Manager Control Server Remote Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of software utilizing Free Download Manager Control Server. The vulnerability is caused due to a boundary error within Free Download Manager Control Server when processing HTTP GET Request. This can be exploited to cause a stack-based buffer overflow via an overly long, specially-crafted argument passed to the affected command.
By exploiting this vulnerability, the return address in the stack can be arbitrarily altered, allowing the auditor to gain control of the target host. After successful exploitation an agent will be deployed. This agent will inherit the user identity and capabilities of the abused service, usually those of the user used to login to the FTP server (for example, ftp). However, the UID (as opposite to the EUID) of the agent will be that of the super user in most cases (usually 0), and it can be changed by using the setuid module (see "setuid").
