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.

VMware vCenter Server Java JMX-RMI Remote Code Execution Exploit
VMware vCenter Server is prone to a remote vulnerability that allows attackers to take advantage of an insecure deployment of the JMX/RMI service used to manage and monitor the Java Virtual Machine. By exploiting known methods, it is possible to remotely load an MLet file from an attacker controlled web server that points at a jar file.
Microsoft Windows NDIS Pool Overflow Vulnerability DoS (MS15-117)
A vulnerability in the Network Driver Interface Standard (NDIS) implementation in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, and Windows 7 SP1 allows local users to trigger buffer overflow. This allows unprivileged local user to cause an invalid dereference in kernel mode, which produces a BSoD.
WordPress Landing Pages Plugin OS Command Injection Exploit
An OS Command Injection vulnerability exists in the "Landing Pages" plugin for WordPress. This module verifies the vulnerability and provides a OS Command Inection Agent.
The vulnerability is due to an error while parsing crafted PRX files which can result in an buffer overflow. This module runs a malicious web site on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.

Microsoft Group Policy Preferences Exploit (MS14-025)
This module exploits a vulnerability in Microsoft's implementation of the Group Policy Preferences password encryption.
There is a directory traversal flaw in the fileserver upload/download functionality used for blob messages in Apache ActiveMQ. The vulnerability allows writing files anywhere in the filesystem as long as the user running the process has permissions to do so. It also allows to copy local files to local or remote destinations, the later by means of abusing UNC paths. This module first uses the vulnerability to upload the credentials for the web administration application to a SMB server and parses the credentials.
Linux Blueman D-Bus Service EnableNetwork Privilege Escalation Exploit
The EnableNetwork method in the org.blueman.Mechanism D-Bus service of Blueman, a Bluetooth Manager, receives untrusted Python code provided by unprivileged users and evaluates it as root. This can be leveraged by a local unprivileged attacker to gain root privileges.
Linux Overlayfs ovl_setattr Local Privilege Escalation Exploit
This module exploits a vulnerability in Linux. The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.
Linux abrt sosreport Symlink Privilege Escalation Exploit
The 'sosreport' program, part of the ABRT bug reporting system used in Red Hat Enterprise Linux, does not handle symbolic links correctly when writing core dumps of ABRT programs to the ABRT dump directory (/var/tmp/abrt). This can be leveraged by local unprivileged attackers to gain root privileges on vulnerable systems.
The default Jenkins configuration allows to execute groovy scripts without being authenticated.

Impact
Microsoft Windows Media Center MCL URL File Disclosure Exploit (MS15-134)
Windows Media Center MCL files can specify a URL to be automatically loaded within Media Center. A specially crafted MCL file can abuse this URL parameter in order to trick Windows Media Center into rendering the very same MCL file as a local HTML file within the application's embedded web browser. This way, attacker-controlled Javascript code can run in the context of embedded IE's Local Machine Zone with no security prompts, since Media Center does not opt-in for the Local Machine Zone Lockdown policy.
The vulnerability is due to an error while parsing ThinApp compressed files which can result in an buffer overflow. This module runs a malicious web site on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.
