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.

Atlassian Bamboo is prone to a remote vulnerability that allows attackers to take advantage of a deserialization vulnerability present in the commons-collections Java library.
By exploiting known methods, it is possible to remotely load a InvokerTransformer Java class, which allows the execution of system commands.
TrendMicro node.js HTTP Server Remote Code Execution Exploit
The Password Manager component installed by various Trend Micro products runs a Node.js HTTP server by default. This web server opens multiple HTTP RPC ports for handling API requests. For example, the openUrlInDefaultBrowser API function, which internally maps to a ShellExecute function call, allows and attacker to execute arbitrary commands on localhost without the need of any type of credentials.
Web Application Authentication Testing Improvement
Improvement on Web Application Authentication Testing parameters to use a higher number of values between the authentication probes.

Apple Mac OS X XPC Entitlements Local Privilege Escalation Exploit
The Admin framework in Apple OS X contains a hidden backdoor API to gain root privileges. A local user can exploit this flaw in the checking of XPC entitlements.
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.
There are several API endpoints that allow low-privilege users to POST XML files that then get deserialized by Jenkins. Maliciously crafted XML files sent to these API endpoints could result in arbitrary code execution.

There are several API endpoints that allow low-privilege users to POST XML files that then get deserialized by Jenkins. Maliciously crafted XML files sent to these API endpoints could result in arbitrary code execution. This update adds support for HTTPS and IPv6. It also allows to change the application root path.
Exim perl_startup Configuration Variable Local Privilege Escalation Exploit
Exim installations compiled with Perl support do not perform sanitation of the environment before loading a perl script defined with perl_startup setting in exim config file. This can be exploited by malicious local attackers to gain root privileges.
Microsoft Internet Explorer VBScript Filter Type Confusion Exploit (MS15-106)
The Filter function of the VBScript engine in Microsoft Internet Explorer is prone to a type confusion vulnerability when processing specially crafted parameters. This vulnerability allows attackers to execute arbitrary code on vulnerable machines by enticing unsuspecting users to visit a specially crafted website.
The amd64_set_ldt() function in sys/amd64/amd64/sys_machdep.c in the FreeBSD kernel code is prone to an integer signedness error when processing a system call with specially crafted parameters originated from user space. This issue ultimately leads to a kernel heap overflow, which can be used by unprivileged local attackers to cause a kernel panic and crash the machine.
Advantech WebAccess webvrpcs Service BwWebSvc ProjectName sprintf Buffer Overflow Exploit
The specific flaw exists within the implementation of the 0x13C83 IOCTL in the BwOpcTool subsystem. A stack-based buffer overflow vulnerability exists in a call to memcpy using the ProjectName parameter. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system.

Netgear ProSafe Network Management System Arbitrary File Upload Vulnerability Exploit
A vulnerability exists in the FileUpload2Controller servlet. This servlet allows unauthenticated file uploads. By uploading a JSP file, an attacker can achieve remote code execution.
Advantech WebAccess webvrpcs Service DrawSrv TagGroup Buffer Overflow Exploit
The specific flaw exists within the implementation of the 0x280A IOCTL in the DrawSrv subsystem. A stack-based buffer overflow vulnerability exists in a call to strcpy. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system.
Linux Kernel join_session_keyring Reference Counting Privilege Escalation Exploit
The join_session_keyring() function in security/keys/process_keys.c in the Linux kernel is prone to a reference counter overflow that occurs when a process repeatedly tries to join an already existing keyring. This vulnerability can be leveraged by local unprivileged attackers to gain root privileges on the affected systems.
