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.

Product Name
MSRPC Messenger exploit
There is a buffer overflow vulnerability in the Microsoft Windows Messenger service. This allows an attacker to execute arbitrary code with System privileges. The vulnerability is triggered by sending a malformed message to the vulnerable host. Manipulating the length of the packet allows portions of the heap memory to be overwritten with user defined data.
Simple Web Server GET Request Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of software utilizing Simple Web Server. The vulnerability is caused due to a boundary error within Simple Web 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. Authentication is not required to exploit this vulnerability.
This module exploits a remote stack-based buffer overflow in Siemens Tecnomatix FactoryLink by sending a malformed packet to CSService listening on port 7580.

Impact
Samba lsa_io_trans_names buffer overflow exploit
This module exploits a buffer overflow vulnerability when parsing RPC requests through the LSA RPC interface in Samba 3.x. The exploit is triggered by sending a specially crafted RPC LsarLookupSids request to a vulnerable computer. After successful exploitation an agent will be deployed. This agent will inherit the user identity and capabilities of the samba server. However, the euid (as opposite to the uid) of the agent may be not that of the super user (usually is "nobody"), and by using the setuid module (see setuid module documentation), it can be changed to zero (root).
An anonymous user can gain remote root access due to a buffer overflow caused by a StrnCpy() into a char array (fname) using a non-constant length (namelen).
Safenet SoftRemote IKE Service Remote Buffer Overflow Exploit
This module exploits a remote stack-based buffer overflow in the Safenet IKE Service (included in several VPN clients) by sending a specially crafted packet to UDP port 62514.
RSH Daemon for Windows Remote Buffer Overflow Exploit
This module exploits a stack-based buffer overflow vulnerability in the Windows RSH application (rshd.exe). The module sends a specially crafted packet to port 514/tcp and installs an agent if successful.
This module exploits a stack-based buffer overflow in the Windows Routing and Remote Access Service. Since the service is hosted inside svchost.exe, a failed exploit attempt can cause other system services to fail as well. A valid username and password is required to exploit this flaw.
The rpc.statd program passes user-supplied data to the syslog() function as a format string. If there is no input validation of this string, a malicious user can inject machine code to be executed with the privileges of the rpc.statd process, typically root. This is a ONE SHOT exploit. This exploit is able to attack a Redhat and a Suse system in a 'one shot' attack.
Ricoh DC DL-10 SR10 FTP USER Command Buffer Overflow Exploit
Ricoh DC's DL-10 SR10 FTP Server is prone to a buffer-overflow vulnerability when handling data through the USER command. This can be exploited by supplying a long string of data to the affected command. In order to trigger the vulnerability, the log file of the application must not be empty. The vulnerable version of SR10.exe file is 1.0.0.520
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 module exploits a buffer overflow vulnerability in RealServer 8.0 when constructing error messages. After successful exploitation an agent will be installed.
This module exploits an array overflow vulnerability in RealServers and Helix Servers 8.0 and higher. The bug is present in the code for accessing RealServer's registry (or configuration options), in the constructor for the class ServRegKey (at least in the open source version of Helix Server). The bug occurs when a string is splitted in several substrings, using '.' as separator.
RealNetworks Helix Server AgentX Remote Buffer Overflow Exploit
This module exploits a remote stack-based buffer overflow vulnerability in AgentX++, as distributed with Helix Server, by sending multiple blocks of data to the port 705/TCP. Authentication is not required to exploit this vulnerability.
A stack overflow found in RabidHamster R4's web server by supplying a malformed HTTP request when generating a log.

Quick TFTP Server Pro Mode Remote Buffer Overflow Exploit
This module exploits a buffer overflow vulnerability in Quick TFTP Server Pro when processing a very large mode field in a read or write request and installs an agent if successful. This vulnerability can be exploited remotely by sending a very long TFTP Error Packet to both service or standalone versions.
This module exploit PureFTPd service using Bash Command Injection Vulnerability (CVE 2014-6278). The module works if the service is handling the incoming authentication connections via a bash script.
This module exploits a command injection error in Samba 3. For this exploit to work, the "username map script" option must be enabled on smb.conf, the samba configuration file. The agent will normally run as the "nobody" user, and will have limited capabilities.
SIELCO SISTEMI Winlog Malformed Packet Stack Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of software utilizing SIELCO SISTEMI Winlog when Run TCP/IP server is enabled in CONFIGURATION-OPTIONS-TCP/IP. The vulnerability is caused due to a boundary error within SIELCO SISTEMI Winlog when processing a malformed request. This can be exploited to cause a stack-based buffer overflow in Runtime.exe via a crafted 0x02 opcode packet. Authentication is not required to exploit this vulnerability.
SIDVault LDAP Server Remote Buffer Overflow Exploit
This module exploits a buffer overflow vulnerability in the LDAP service (sidvault.exe) of the SIDVault LDAP application. The exploit triggers a stack-based buffer overflow by sending a specially crafted packet to port 389/TCP of the vulnerable system and installs an agent if successful.
Serv-U supports an FTP command, "MDTM", which is used to change a file's modification time. An internal memory buffer may be overrun while handling an malformed time zone as MDTM argument. This condition may be exploited by attackers to ultimately execute instructions with the privileges of the serv-u process, typically administrator or system. The Serv-U server will be left inaccessible after successful exploitation.
