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.

A vulnerability in the installer component of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated local attacker to copy user-supplied files to system level directories with system level privileges. The vulnerability is due to the incorrect handling of directory paths. An attacker could exploit this vulnerability by creating a malicious file and copying the file to a system directory. An exploit could allow the attacker to copy malicious files to arbitrary locations with system level privileges.
The specific flaw exists within the parsing of wTextLen information within VU3 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
ATI Technologies Driver atillk64 Kernel Arbitrary Read Write Local Privilege Escalation Exploit
AMD ATI atillk64 allows low-privileged users to interact directly with physical memory by calling one of several driver routines that map physical memory into the virtual address space of the calling process. This could enable low-privileged users to achieve NT AUTHORITY\SYSTEM privileges via a DeviceIoControl call associated with MmMapIoSpace, IoAllocateMdl, MmBuildMdlForNonPagedPool, or MmMapLockedPages.
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the implementation of IOCTL 0x00005227 in DATACORE.exe. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator.
Microsoft Exchange Validation Key Remote OS Command Injection Exploit Update
.NET deserialization vulnerability in the Microsoft Exchange Control Panel web page allows authenticated attackers to execute OS commands with SYSTEM privileges.
The lack of randomization in the validationKey and decryptionKey values at installation allows an attacker to create a crafted viewstate to execute OS commands via .NET deserialization.
This update adds payload generation error detection and dependencies documentation.
The specific flaw exists within the handling of XML files. When parsing the szFilename attribute of the MulStatus element. This update adds CVE number.
Deserialization of Untrusted Data in Liferay Portal prior to 7.2.1 CE GA2 allows remote attackers to execute arbitrary code via JSON web services (JSONWS).
Oracle Coherence T3 ReflectionExtractor Deserialization Vulnerability Remote Code Execution
Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Caching,CacheStore,Invocation). Supported versions that are affected are 3.7.1.17, 12.1.3.0.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via T3 to compromise Oracle Coherence. Successful attacks of this vulnerability can result in takeover of Oracle Coherence.
Windows Search Indexer get_RootURL Race Condition Privilege Escalation Exploit
A race condition exists in Windows Search Indexer, when the put_RootURL function wrote a user-controlled data in the memory of CSearchRoot+0x14.AT the same time, the get_RootURL function read the data located in the memory of CSearchRoot+0x14.
The vulnerability was caused by the access to a shared variable between two different methods of the same instance .
The sub_resource_create function of class M_devices in m_devices.php of Open-AudIT 3.2.2 allows remote authenticated users to upload arbitrary PHP files, allowing the execution of arbitrary php code in the system.

Microsoft Windows Background Intelligent Transfer Service Elevation of Privilege Vulnerability Exploit
An elevation of privilege vulnerability exists when the Windows Background Intelligent Transfer Service (BITS) improperly handles symbolic links. An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status and take control of an affected system.
Kinetica Admin getLogs Function Remote OS Command Injection Exploit
The Kinetica Admin web application did not properly sanitise the input for the function getLogs. This lack of sanitisation could be exploited to allow an authenticated attacker to run remote code on the underlying operating system.
