Library of expert validated exploits for safe and effective pen tests
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. Whether written by our own internal team or by a third party like ExCraft, 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.

IE VML buffer overflow exploit
This module exploits a buffer overflow in the Microsoft Internet Explorer via a Stack-based buffer overflow in Microsoft Internet Explorer 6.0 allowing remote attackers to execute arbitrary code via a long fill parameter within a rect tag in a Vector Markup Language (VML) file. WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations.
The suid_dumpable support in Linux kernel 2.6.13 up to versions before 2.6.17.4, and 2.6.16 before 2.6.16.24, allows a local user to cause a denial of service (disk consumption) and possibly gain privileges via the PR_SET_DUMPABLE argument of the prctl function and a program that causes a core dump file to be created in a directory for which the user does not have permissions.
This module exploits a stack-based buffer overflow in Microsoft Windows Media Player 9 and 10 allows remote attackers to execute arbitrary code via a PNG image with a large chunk size.
Microsoft Internet Explorer 6 Service Pack 1 on Windows 2000 and Windows XP SP1 contains a vulnerability when viewing a web site using the HTTP 1.1 protocol. If the web site uses HTTP 1.1 compression and contains an overly long URL, a buffer overflow can occur. This vulnerability was introduced with the first release of the MS06-042. This module exploits this vulnerability. WARNING: This is an early release module. This is not the final version of this module.
This module exploits a stack buffer overflow in WinRAR 3.60 beta6 and prior to install a level0 agent. This update adds support to register the exploit into the IMPACT webserver.
This module exploits a stack-based buffer overflow in WINSRV.DLL in the Client Server Runtime System (CSRSS) process. Allows local users to gain privileges via a specially-designed application that provides console window information with a long FaceName value. This update improve the exploit reliability in windows 2003.
The Ubuntu 5.10 installer does not properly clear passwords from the installer log file (questions.dat), and leaves the log file with world-readable permissions, which allows local users to gain privileges
This module exploits a remotely exploitable vulnerability in Windows' Server Service (MS06-040) over Microsoft DCERPC (ports 139 and 445). This update adds support for Windows XP SP0 and SP1.
The server driver (srv.sys) in Microsoft Windows 2000 SP4, Server 2003 SP1 and earlier, and XP SP2 and earlier allows remote attackers to cause a denial of service (crash) via a crafted packet on an SMB PIPE that triggers a null dereference. While investigating the Microsoft Server Service Mailslot heap overflow vulnerability reported in Microsoft Security Bulletin MS06-035 we discovered a second bug in the server service. This module exploits this vulnerability. For more info go to http://www.coresecurity.com/common/showdoc.php?idx=562&idxseccion=10
This module exploits a remotely exploitable vulnerability in Windows' Server Service (MS06-040) over Microsoft DCERPC (ports 139 and 445). WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations. Since this module is not the final version it may contain bugs or have limited functionality and may not have complete or accurate documentation.
do_command.c in Vixie cron (vixie-cron) 4.1 does not check the return code of a setuid call, which might allow local users to gain root privileges if setuid fails in cases such as PAM failures or resource limits, as originally demonstrated by a program that exceeds the process limits as defined in /etc/security/limits.conf
This module exploits a remote vulnerability that could allow an attacker to send a specially crafted SMB message to an affected system causing a denial of service (MS06-035). WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations. Since this module is not the final version it may contain bugs or have limited functionality and may not have complete or accurate documentation.
This module sends a series of UDP packets containing malformed IAX2 requests that will crash vulnerable listening IAX clients. If a broadcast IP address is specified, an entire subnetwork can be attacked in a single run.
This module exploits a stack based buffer overflow handling the mail headers in the OWA (Outlook Web Access) service when processing meeting requests of Exchange Server clients (MS06-019).
X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile.
This exploit simulates a RealVNC client and establishes a connection with a Real VNC server without using a password. After that, it opens a console, writes the exploit and executes it in ntsd.exe
This exploit proxies TCP connections to a remote (or local) VNC server and monitors the list of supported authentication methods of the server. Connecting clients will receive a dummy list consisting of only one authentication method (no password).
This is a denial of service exploit for a vulnerability in the MSDTC component of windows systems (MS06-018). This update fixes the correct CVE number (CVE-2006-1184)
This update will add DCERPC encryption to some MSRPC exploits. The result is that, when enabled, all the 'Stub data' for DCERPC requests will be encrypted, thus hiding the real content.
The logging function used by the Ultr@VNC server is affected by a limited buffer-overflow caused by two strcat calls which add a Windows error message to the output buffer causing the server to crash and stop responding to further connections.
