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.

JBoss Application Server is prone to a remote vulnerability due to deserialization of untrusted inputs, allowing attackers to instantiate arbitrary Java objects leading to remote code execution.
Jenkins is prone to a remote vulnerability due to deserialization of untrusted inputs, allowing attackers to instantiate arbitrary Java objects leading to remote code execution.
IBM WebSphere Application Server is prone to a remote vulnerability due to deserialization of untrusted inputs, allowing attackers to instantiate arbitrary java objects leading to remote code execution.
The specific flaw exists within the VPORTSDK.VPortSDKCtrl.1 ActiveX control. By passing an overly long string to the GetClientReg method's Name parameter.
HP LoadRunner Controller Scenario File Buffer Overflow Exploit
The specific flaw exists within the handling of scenario files (.lrs). By manipulating a scenario file's values, an attacker can cause a fixed-length stack buffer to overflow.
Linux fusermount Environment Variable Privilege Escalation Exploit
The 'fusermount' binary, part of the FUSE system in Linux, executes the /bin/mount binary with ruid set to 0 without clearing the environment variables provided by unprivileged users.
This flaw can be leveraged by local unprivileged users to gain root privileges by leveraging the functionality provided by the LIBMOUNT_MTAB environment variable to overwrite an arbitrary file on the affected system.
ManageEngine EventLog Analyzer is vulnerable to abuse a SQL query functionality that allows attackers to insert and export a crafted JSP using 'guest' credentials allowing us to install an agent.
Symantec Endpoint Protection Kernel Pool Overflow Privilege Escalation Exploit Update
Buffer overflow in the sysplant driver in Symantec Endpoint Protection (SEP) Client 11.x and 12.x before 12.1 RU4 MP1b, and Small Business Edition before SEP 12.1, allows local users to execute arbitrary code via a long argument to a 0x00222084 IOCTL call.
This update introduces variations in the SWF files of "Adobe Flash Player ByteArray valueOf Use-After-Free Exploit" and "Adobe Flash Player shared ByteArray Use-After-Free Exploit" modules to avoid antivirus signatures.
HP Client Automation Remote Code Execution Exploit
This module exploits a command injection vulnerability in HP Client Automation. The flaw exists within the radexecd.exe component which listens by default on TCP port 3465. When handling a remote execution request the process does not properly authenticate the user issuing the request. The command to be executed is also not properly sanitized. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of SYSTEM.
Authentication is not required to exploit this vulnerability.
A vulnerability in ElasticSearch versions 1.4.0 to 1.4.2 allows execution of unsandboxed Groovy code. This module installs an OS agent in vulnerable targets.
Microsoft Windows MS-DOS Device Name Privilege Escalation Exploit(MS15-038)
An elevation of privilege vulnerability exists when Windows kernel does not properly constrain impersonation levels.
The vulnerability occurs because a user can place symlinks for the system drives in the per-login session device map and the kernel will follow them during impersonation.
An attacker who successfully exploited this vulnerability may, for example, redirect a call to LoadLibrary, from a system service (when impersonating), to an arbitrary location.
This update improves the functionality of the impact agent running in windows 2000.

Borland AccuRev Reprise License Server edit_lf_process Write Arbitrary Files Exploit
The specific flaw exists within the edit_lf_process resource of the AccuRev Reprise License Manager service. The issue lies in the ability to write arbitrary files with controlled data. An attacker could leverage this vulnerability to execute arbitrary code under the context of SYSTEM.
The map_yp_alias function in functions/imap_general.php in SquirrelMail before 1.4.18 and NaSMail before 1.7 allows remote attackers to execute arbitrary commands via shell metacharacters in a username string that is used by the ypmatch program. This module works if map:map_yp_alias is set as the imap server address in config.php, which is not the default setting.
This update improves os detection and adds runtime cost.

Apache ActiveMQ Path Traversal Exploit
This update introduces an exploit for Apache ActiveMQ. The vulnerable versions present a path traversal vulnerability in default instalations that allows writing files to arbitrary filesystem locations, with the permissions of the user running the ActiveMQ process.
This module leverages the vulnerability to install an agent. This exploit doesn't require authentication.
The vulnerability is only present when the application is running in a Windows system.
Adobe Acrobat Pro Multiple Vulnerabilities Exploit
A specially crafted argument to makeMeasurement will leave objects in an inconsistent state and can produce a Buffer Overflow. This data can later be retrieved via a call to dumpMeasureData.
Finally using NSendApprovalToAuthorEnabled method it is possible to bypass the Javascript API restrictions.
Linux apport Race Condition Privilege Escalation Exploit Update
This module exploits a vulnerability in the Linux apport application. The apport application can be forced to drop privileges to uid 0 and write a corefile anywhere on the system. This can be used to write a corefile with crafted contents in a suitable location to gain root privileges.
This updates improves the way some files are cleaned up after a failed exploitation attempt.
This module exploit three different vulnerabilities in Symantec Endpoint Protection Manager (SEPM) in order to install an agent on a vunlerable target machine.
CVE-2015-1486 allows unauthenticated attackers access to SEPM.
CVE-2015-1487 allows reading and writing arbitrary files, resulting in the execution of arbitrary commands with 'NT Service\semsrv' privileges.
CVE-2015-1489 allows the execution of arbitrary OS commands with 'NT Authority\SYSTEM' privileges.
