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.

This module exploits a path traversal vulnerability in Novell ZENworks Asset Management. The specific flaw exists within a servlet provided within the Novell Zenworks distribution for uploading files. When processing the path name for the file, the servlet will allow a user to inject path traversal entities into the filename. Then, when the servlet downloads the provided file, the destination will store it to the user-provided location.
This module exploits a remote stack-based buffer overflow vulnerability in the Preboot Service component of Novell ZENworks Configuration Management, by sending a specially crafted packet to the port 998/TCP.

Novell ZENworks Configuration Management Preboot Service Remote Buffer Overflow Exploit
This module exploits a remote stack-based buffer overflow vulnerability in the Preboot Service component of Novell ZENworks Configuration Management, by sending a specially crafted packet to the port 998/TCP.
A remote code execution vulnerability in the UploadServlet component of Novell ZENworks Configuration Management allows remote attackers to execute arbitrary code. This module uploads an arbitrary .WAR file on the target in order to deploy an agent on it.
Novell ZENworks Mobile Management Remote Code Execution Exploit
This module exploits a vulnerability in the Novell ZENworks Mobile Management application by injecting code in the PHP session file and leveraging a Local File Inclusion in mdm.php to execute the injected PHP code. The agent installed by this exploit will run with the privileges of the "IUSR" user.
Now SMS MMS Gateway Web Authorization Buffer Overflow Exploit
A vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of software utilizing the web interface of Now SMS MMS Gateway. The vulnerability is caused due to a boundary error within Now SMS MMS Gateway web interface which listens on port 8800 and allows the users to use the gateway for sending various types of messages. This can be exploited to cause a stack-based buffer overflow via an overly long, specially-crafted argument passed to the web interface. Authentication is not required to exploit this vulnerability.
Omni-NFS Enterprise FTP Server Buffer Overflow Exploit
Omni-NFS Enterprise is a suite of network related tools, including an FTP Server. That server is vulnerable to stack-based buffer overflow caused by malicious FTP requests, and this module exploits that vulnerability in order to install an agent on the target machine.

Openftpd Server Buffer Overflow Exploit
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.
This exploit abuses an integer overflow condition present in sshd's authentication for bsdauth and skey authentication modes. After successful exploitation an agent will be deployed. The agent will be installed with root privileges. Tests performed in our lab required up to 1 hour to find the needed address in the raw brute forcing mode.
This module exploits an error in the PAM authentication code present in certain portable versions of OpenSSH. Vulnerable servers allow valid users to login with invalid passwords.
This module exploits a vulnerability in the OpenSSL library. OpenSSL versions 0.9.7-beta, 0.9.7, 0.9.7a and 0.9.7b are affected. The corresponding OpenSSL advisory states: "Certain ASN.1 encodings that are rejected as invalid by the parser can trigger a bug in the deallocation of the corresponding data structure". This module triggers this deallocation and abuses the dynamic memory allocator of vulnerable Linux systems in order to execute arbitrary code.
This module exploits a vulnerability in the OpenSSL library, which is used by Apache if HTTPS support is provided. OpenSSL versions 0.9.7-beta, 0.9.7, 0.9.7a and 0.9.7b are affected. The corresponding OpenSSL advisory states: "Certain ASN.1 encodings that are rejected as invalid by the parser can trigger a bug in the deallocation of the corresponding data structure". This module triggers this deallocation and abuses the dynamic memory allocator of vulnerable Linux systems in order to execute arbitrary code. This module can not be launched from an agent.
A missing boundary check in the TLS Heartbeat extension in OpenSSL can be abused by remote attackers to read up to 64 kb of memory from the server. This memory disclosure vulnerability can be used by remote unauthenticated attackers to obtain sensitive information from the affected server, including private keys and session cookies. This module will check if the target machine is vulnerable and it will try to dump memory contents to the Module Log window. This memory dump may contain sensitive data, as explained above.
This module exploits a stack based buffer overflow in the Oracle process. This is done by sending an 'AUTH_SESSKEY' property longer than the 64 bytes expected.
Oracle Database Server is prone to a remote vulnerability that allows attackers to poison the data handled by the remote 'TNS Listener' component of the application. This module tries to verify if the vulnerability is present in the 'TNS Listener' component of the database server, without deploying an agent.
