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.

Insufficient input validation in the management interface of Solarwinds LEM Management Virtual Appliance v6.3.1 can be leveraged in order to execute arbitrary commands.
This can lead to shell access to the underlying operating system as root.
Linux Kernel DCCP_PKT_REQUEST Privilege Escalation Exploit
This module exploits a double-free vulnerability in the Linux Kernel. The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to escalate privileges via an application that makes an IPV6_RECVPKTINFO setsockopt system call.
The specific flaw exists within processing of the AddStringUserProperty method within the UCCDRAW.UCCDrawCtrl.1 ActiveX control. The process does not properly validate a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process.
Linux Kernel SO_SNDBUFFORCE Privilege Escalation Exploit
This module exploits a signedness issue in the Linux Kernel. The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to escalate privileges.
The specific flaw exists within the dbman.exe service, which listens on TCP port 2810 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call.
Microsoft Office Word OLE2Link OLE Object Exploit Update
This module exploits a vulnerability in Microsoft Office Word. The flaw is related in how Microsoft Word handles OleLink objects. It is possible to open a RTF file and execute arbitrary code in vulnerables installations of Microsoft Office Word.
This vulnerability was originally seen being exploited in the wild starting in October 2016.
This module adds support for Microsoft Office 2010, Microsoft Office 2013 and Microsoft Office 2016.

Impact
Microsoft Windows COM Aggregate Marshaler Type Confusion Exploit
An elevation of privilege exists in Windows COM Aggregate Marshaler. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges.
Microsoft Windows SMB Pool Overflow Remote Code Execution (MS17-010)
This module exploits the ms17-010 vulnerability by taking advantage of a remote pool overflow in the smb transaction handling code of the windows smb driver.
Microsoft Office Malformed EPS Use-After-Free File Vulnerability Exploit
Use After Free in Microsoft Office allows remote attackers to execute arbitrary code via crafted EPS file in an Office document, leading to improper memory allocation.
This module uses a directory traversal vulnerability in the file import feature in Nuxeo Platform CMS to upload a JSP to gain arbitrary code execution on the affected system.

Microsoft Office Word OLE2Link OLE Object Exploit
This module exploits a vulnerability in Microsoft Office Word. The flaw is related in how Microsoft Word handles OleLink objects. It is possible to open a RTF file and execute arbitrary code in vulnerables installations of Microsoft Office Word.
This vulnerability was originally seen being exploited in the wild starting in October 2016.
Disk Sorter Enterprise server is prone to a buffer-overflow vulnerability when handling a crafted GET request, this can trigger an overflow in a finite-sized internal memory buffer, and install an agent with SYSTEM privileges.
This module exploits two vulnerabilities in Trend Micro Threat Discovery Appliance.
The first is an authentication bypass vulnerability via a file delete in logoff.cgi which resets the admin password back to 'admin' upon a reboot. This is useful if the password for the admin user is unknown.
The second is an authenticated command injection flaw using the timezone parameter in the admin_sys_time.cgi interface.
Microsoft Windows OLE Package Manager Code Execution Exploit (MS14-064) Update
Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allow remote attackers to execute arbitrary code via a crafted OLE object, as exploited in the wild in October 2014 with a crafted PowerPoint document.
This update resolves an issue in the PowerShell feature.

PHPMailer Remote Command Execution Exploit Update
PHPMailer is prone to a abuse the mailSend function. This vulnerability allows remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code via a \" (backslash double quote) in a crafted Sender property.
This updates adds x86/x64 and HTTP/HTTPS Channel Support.
HPE Intelligent Management Center is prone to a remote vulnerability that allows attackers to take advantage of an insecure deployment of the RMI Registry service used to manage and monitor the Java Virtual Machine.
