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.

Web Application Authentication Testing Improvement
Improvement on Web Application Authentication Testing parameters to use a higher number of values between the authentication probes.
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.

This update adds support for HTTPS and IPv6. It also allows to change the application root path.
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.
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.
The specific flaw exists within the activate_doit function of the service. The issue lies in the handling of the actserver parameter which can result in overflowing a stack-based buffer.
NVIDIA Stereoscopic 3D Driver Service Privilege Escalation
This module will exploit a vulnerability in the NVIDIA Stereoscopic 3D Driver Service. It will wait for users to login on the target system, installing agents for every user, until being able to install an agent for a user in the Built In Administrators group.
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.
Apple Mac OS X DYLD_PRINT_TO_FILE Privilege Escalation Exploit
This module exploits a vulnerability present in Mac OS X. dyld in Apple OS X before 10.10.5 does not properly validate pathnames in the environment, which allows local users to gain root privileges via the DYLD_PRINT_TO_FILE environment variable.
Oracle Application Testing Suite UploadServlet Servlet Remote Code Execution Exploit
A vulnerability exists in the UploadServlet servlet. By providing a filename header containing a directory traversal, an attacker can upload a file to an arbitrary location on the system.
This module abuses the auto deploy feature in the server in order to achieve remote code execution.
Improvement on Web Application Authentication Testing parameters to use a high number of values between the authentication probes.
Exploits / Authentication Weakness
Impact Professional
Oracle Application Testing Suite UploadFileAction Servlet Remote Code Execution Exploit
A vulnerability exists in the UploadFileAction servlet. By providing a fileType parameter of "*" to the UploadFileUpload page, an attacker can upload a file to an arbitrary location on the system.
This module abuses the auto deploy feature in the server in order to achieve remote code execution. Also, this module makes use of an authentication bypass vulnerability to perform the attack.
Adobe Acrobat Reader armsvc Service Privilege Escalation Exploit
Adobe Reader and Acrobat 10.x before 10.1.15 and 11.x before 11.0.12, Acrobat and Acrobat Reader DC Classic before 2015.006.30060, and Acrobat and Acrobat Reader DC Continuous before 2015.008.20082 on Windows and OS X allow attackers to bypass intended access restrictions and perform a transition from Low Integrity to Medium Integrity via unspecified vectors, a different vulnerability than CVE-2015-4446 and CVE-2015-5106.
Spring Boot Default Error Page Expression Language Injection Exploit
Spring Boot Framework 1.2.7 provides a default error page (also known as "Whitelabel Error Page"), that's prone to Spring Expression Language injection when the type of a parameter expected is not expected to be a string but a string is provided. Applications based on Spring Boot that don't deactivate the feature, or customize it in such a way as to stop the injection, are thus susceptible to execution of some Java statements and, in particular, to OS command injections.
