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.

Serv-U chmod exploit
An internal memory buffer may be overrun while handling "site chmod" command with an overly long filename. This condition may be exploited by attackers to ultimately execute instructions with the privileges of the serv-u process, typically administrator or system. This bug requires the FTP user to have write privileges on at least one directory to be exploited. The Serv-U server will be left inaccessible after successful exploitation.
Schneider Electric Serial Modbus Driver Buffer Overflow Exploit
The Modbus Serial Driver creates a listener on Port 27700/TCP. When a connection is made, the Modbus Application Header is first read into a buffer. If a large buffer size is specified in this header, a stack-based buffer overflow can be done.
Schneider Electric Interactive Graphical SCADA System Buffer Overflow Exploit
This Stack-based buffer overflow exploits a vulnerability in Schneider Electric's Interactive Graphical SCADA System (IGSS) that allows remote attackers to execute arbitrary code by sending a specially crafted packet to TCP port-12397.
Schneider Electric Accutech Manager Heap Overflow Exploit
This module exploits a heap overflow vulnerability in the Schneider Electric Accutech Manager Server by sending a malformed packet to the 2537/TCP port to crash the application.
SAP Netweaver Message Server _MsJ2EE_AddStatistics Memory Corruption Exploit
The Message Server component of SAP Netweaver is prone to a memory corruption vulnerability when the _MsJ2EE_AddStatistics function handles a specially crafted request with iflag value 0x0c MS_J2EE_SEND_TO_CLUSTERID, or 0x0d MS_J2EE_SEND_BROADCAST. This vulnerability can be exploited by remote unauthenticated attackers to execute arbitrary code on the vulnerable server. This exploit bypasses Data Execution Prevention (DEP). Agents installed with this module will run under the SAPService user account.
SAP Netweaver DiagTraceR3Info Remote Buffer Overflow Exploit
The DiagTraceR3Info function of the disp+work.exe component of SAP Netweaver is prone to a remote buffer overflow when the worker process trace level is set to values 2 or 3 for the Dialog Processor component. This vulnerability can be exploited to execute arbitrary code on the vulnerable machine by sending a specially crafted packet containing ST_R3INFO CODEPAGE items. This exploit bypasses Data Execution Prevention (DEP). Agents installed with this module will run under the SAPServiceSNP user account.
This module exploits a stack-based buffer overflow vulnerability in the waHTTP.exe (SAP DB Web Server) component included with the SAP DB. The exploit is triggered by sending an unauthenticated, specially crafted HTTP request to the default port 9999/TCP.
Sami FTP Server Authentication Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on installations of Sami FTP Server, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error within the authentication process. This can be exploited to cause a stack-based buffer overflow by sending an overly long, specially-crafted password to the affected server and waiting for the administrator of Sami FTP Server to set focus on the GUI of the program in order to deploy an agent.
This module exploit PureFTPd service using Bash Command Injection Vulnerability (CVE 2014-6271). The module works if the service is handling the incoming authentication connections via a bash script.
TwonkyMedia Server Error Page Cross Site Scripting Exploit
Input passed via the URL is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Impact
RealVNC 4.1.1 Authentication Exploit Proxy
Exploits a vulnerability in the Real VNC server to bypass the password authentication. A compatible VNC client is required. 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). Unlike other exploits, this module does not deploy any agents.
POODLE TLS1.x to SSLv3 Downgrading Vulnerability Exploit
Before using this module please consider that this is not an actual one-step exploit but a tool that allows our community to confirm if a target infrastructure is vulnerable to Poodle attack by executing a PoC (Proof of Concept). This module is not meant to be used against a victim like most Impact exploits are. Further, to just scan your network for weak ciphers, see the "Test SSL Ciphers" in Impact's Web tab.
The SSL protocol, as used in Oracle Java, encrypts data by using CBC mode with chained initialization vectors. This weakness allows to decrypt HTTP headers by a chosen plain text attack, thus obtaining browser cookies from the target system's browser corresponding to a given HTTPS server. The cookies could then be used by the user to do a session hijacking attack. This module launches the attack against target systems. This systems must be running a browser with the vulnerable Java version for this exploit to work.
Microsoft Windows LNK Shortcut Automatic DLL Loading Exploit (MS15-020)
Microsoft Windows is prone to a vulnerability that may allow a DLL file to be automatically loaded because the software fails to handle LNK files properly. Specifically, the issue occurs when loading the icon of a shortcut file. A specially crafted LNK file can cause Windows to automatically execute code that is specified by the shortcut file. The attacker must entice a victim into viewing a specially crafted shortcut. The shortcut file and the associated binary may be delivered to a user through removable drives. An attacker may exploit this issue to execute arbitrary code.
SlimFTPd LIST Command Remote Buffer Overflow Exploit
SlimFTPd server is prone to a stack buffer overflow when sending a LIST command with an overly-long argument. The attacker needs to be authenticated, so a successful login is required for the exploit to work.
Yokogawa Centum CS 3000 BKHOdeq Remote Buffer Overflow Exploit
This module exploits a stack based buffer overflow in Yokogawa CENTUM CS 3000 by using its BKHOdeq.exe service. The BKHOdeq.exe service, started when running the FCS / Test Function listens by default on TCP/20109, TCP/20171 and UDP/1240. By sending a specially crafted packet to the port TCP/20171 its possible to trigger a stack based buffer overflow which allows execution of arbitrary code with the privileges of the CENTUM user.
