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.

Impact
VMware OVF Tool Format String Exploit
Format String vulnerability in OVF Tool when parsing crafted OVF files.
Microsoft Windows Sysret Instruction Privilege Escalation Exploit (MS12-042)
On Intel CPUs, sysret to non-canonical addresses causes a fault on the sysret instruction itself after the stack pointer is set to guest value but before the current privilege level (CPL) is changed. Windows is vulnerable due to the way the Windows User Mode Scheduler handles system requests. This module exploits the vulnerability and installs an agent with root privileges.
The Java plugin for Internet Explorer is affected by a stack-based buffer overflow when processing the docBase parameter of a Java applet. This can be exploited to execute arbitrary code with the privileges of the current user by enticing the victim to visit a malicious web page. WARNING: This is an early release module. This is not the final version of this module. It is a pre-released version in order to deliver a module as quickly as possible to our customers that may be useful in some situations.
MediaCoder contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error in MediaCoder when handling .M3U files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .M3U file. This update support the last version of the program.

Impact
Microsoft Address Book wab32res DLL Hijacking Exploit
Microsoft Address Book is prone to a vulnerability that may allow execution of wab32res.dll if this dll is located in the same folder than .WAB file.
Real Player MS HelpCenter Command Execution Exploit (MS10-042)
This module exploits a vulnerability caused due to an error in the MPC::HTML::UrlUnescapeW() function in helpctr.exe when escaping URLs, add direct exploitation from Real Player to the original Internet Explorer attack vector.
Microsoft Office Outlook Linked Attachment Exploit (MS10-045) Update
This module exploits a vulnerability in Microsoft Office Outlook when verifying attachments that are attached using the ATTACH_BY_REFERENCE value of the PR_ATTACH_METHOD property in a specially crafted e-mail message. This update uses WebDav.
There is a possible reflected Cross-Site Scripting attack. An attacker able to cause a user to follow a specially crafted malicious link may be able to recover session identifiers or exploit browser vulnerabilities. The template parameter is vulnerable.
Exploits/Cross Site Scripting (XSS)/Known Vulnerabilities
Impact
Microsoft Windows SMB Client Transaction DoS (MS10-020)
This module exploits a remote vulnerability in Microsoft Windows SMB client allowing the attacker to cause a DoS in the remote host.
CastRipper contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error in CastRipper when handling .PLS files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .PLS file.
HP OpenView NNM getnnmdata ICount CGI Buffer Overflow Exploit
This module exploits a stack-based buffer overflow in the getnnmdata.exe CGI application, a component of HP OpenView Network Node Manager, by sending an HTTP request with an invalid value for the ICount parameter.
This module exploits a vulnerability in the CTSUEng.ocx control included in the Creative Software AutoUpdate application. The exploit is triggered when the CacheFolder property processes a long string argument resulting in a stack-based 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. This update add support till 2.0.12.0 version of CTSUEng.ocx.
Zope is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
