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.

VLC is able to handle the subtitles automatically in a very simple way,it just checks the presence of SSA files with the same name of the loaded video and a possible subtitles folder. The functions which handle the MicroDVD, SSA and VPlayer subtitle formats are vulnerable to some stack based buffer-overflow vulnerabilities which can allow an attacker to execute malicious code. This exploit add support for VLC 0.86e version.
Linux Kernel Dirty COW Race Condition Privilege Escalation Exploit Update
This module exploits a race condition vulnerability in the Linux Kernel via MAP_PRIVATE COW.
The bug relies in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
This update improves the post-escalation execution.
TrendMicro is prone to an abuse in the talker.php function to get authentication bypass, combined with the mod TMCSS user-supplied unvalidated input before using it to execute a system calls leads us to execute arbitrary code.

Cisco WebEx ARF File Binary Planting Exploit
The specific flaw exists within the processing of ARF files. While opening an ARF file, WebEx Network Recording Player loads a DLL from an unqualified path. An attacker can leverage this vulnerability to execute code under the context of the current process.
NVIDIA Windows GPU Display Driver R340 before 342.00 and R375 before 375.63 contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x600000D where a value passed from a user to the driver is used without validation leading to escalation of privileges. This update add reliability and speed to the attack.
Linux Kernel UFO Memory Corruption Privilege Escalation Exploit
This module exploits a memory corruption vulnerability in the Linux kernel. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption that can be used by an attacker to escalate privileges.
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.
3S-Smart Software Solutions GmbH CODESYS Web Server Upload Restricted File and Buffer Overflow Exploit
A specially crafted web server request may allow the upload of arbitrary files to the CODESYS Web Server without authorization which may allow remote code execution.
A malicious user could overflow a buffer by providing overly long strings to functions that handle the XML. Because the function does not verify string size before copying to memory, the attacker may then be able to crash the application or run arbitrary code.
phpMyAdmin is prone to a regexp abuse via an eval modifier which can be found in old PHP versions. This vulnerability allows authenticated attackers to run arbitrary php code on the affected server.
PHP versions 4.3.0-5.4.6 had a "feature" which allowed users to run a RegExp Pattern Modifier using PREG_REPLACE_EVAL and may lead to execute code.
phpMyAdmin had an issue in their code that can be exploited from a table replace call.

McAfee ePolicy Orchestrator ActiveX Exploit
This module exploits a vulnerability in the SiteManager ActiveX Control (sitemanager.dll). A validation error in the ExportSiteList() method allows an attacker to run arbitrary code on the target system. The module runs a web server waiting for vulnerable clients (Internet Explorer) to connect to it. When a client connects, it will try to install a Level0v2 agent by exploiting this vulnerability.
Adobe Reader and Acrobat PDF subroutine pointer exploit
This module exploits a vulnerability in Adobe Reader and Acrobat 7.0.8 and earlier, which allows user-assisted remote attackers to execute code via a crafted PDF file that triggers memory corruption and overwrites a subroutine pointer during rendering.
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).
Acunetix Web Vulnerability Scanner GUI Html Script Injection Exploit
Acunetix Web Vulnerability Scanner 10.0 build 20160216 and previous versions, allows remote attackers to execute arbitrary JavaScript code in the context of the scanner GUI.
