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.

An improper authorization vulnerability in Atlassian Confluence allows unauthenticated remote attackers to restore the database of the instance. This allows the creation of unauthorized administrator accounts and the later installation of malicious plugins that allow the execution of OS system commands.
An OGNL injection vulnerability in Confluence Server and Data Center allow an unauthenticated attacker to execute arbitrary code on a Confluence Server or Data Center instance.
The Widget Connector macro in Atlassian Confluence Server allows remote attackers to achieve path traversal and remote code execution via server-side template injection.
The Widget Connector macro in Atlassian Confluence Server allows remote attackers to achieve path traversal and remote code execution via server-side template injection.
This update adds support to control the FTP Server port number and socket timeout.
An OGNL injection vulnerability present in ActionChainResult class of xwork jar file would allow an unauthenticated attacker to execute arbitrary code on a Confluence Server or Data Center instance.
The pdkinstall development plugin is incorrectly enabled in release builds of Atlassian Crowd and Crowd Data Center. An attacker can leverage this vulnerability to install a malicious plugin and execute code in the system.
The ExceptionDelegator component of the XWork framework, part of the Apache Struts 2 web framework, as shipped with Atlassian FishEye, interprets parameters values as OGNL expressions when handling a type conversion error.
This can be exploited to execute arbitrary code on the vulnerable server by tricking a logged-in user with administrator privileges within the FishEye site to visit a specially crafted web page.
The ParametersInterceptor class of XWork framework, part of the Struts 2 web framework, as shipped with Atlassian FishEye, does not properly restrict access to server-side objects. This can be exploited by remote unauthenticated attackers to modify server-side objects and e.g. execute arbitrary commands via specially crafted OGNL (Object-Graph Navigation Language) expressions.
A path traversal vulnerability affects the Issue Collector plugin in Atlassian JIRA. This module exploits that vulnerability to achieve remote code execution. The installed agent will have SYSTEM privileges.
Atlassian Jira Server/Data Center 8.16.0 - Cross-Site Scripting
CVE-2021-26078 The number range searcher component in Jira Server and Jira Data Center before version 8.5.14, from version 8.6.0 before version 8.13.6, and from version 8.14.0 before version 8.16.1 allows remote attackers inject arbitrary HTML or JavaScript via across site scripting (XSS) vulnerability.

Atlassian Jira Template Injection Vulnerability Remote OS Command Injection Exploit
Server-side template injection vulnerability in Jira Server and Data Center, in the ContactAdministrators and the SendBulkMail actions.
If an SMTP server has been configured, then an unauthenticated user can execute code on vulnerable systems using the ContactAdministrators action if the "Contact Administrators Form" is enabled; or an authenticated user can execute code on vulnerable systems using the SendBulkMail action if the user has "JIRA Administrators" access.

Atlassian Questions for Confluence Hardcoded Credentials Vulnerability Checker
Atlassian Questions for Confluence creates a Confluence user account with the username disabledsystemuser.
The disabledsystemuser account is created with a hardcoded password and is added to the confluence-users group, which allows viewing and editing all non-restricted pages within Confluence by default
A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access any pages the confluence-users group has access to.
AtomixMP3 contains a buffer prone to exploitation via an overly long string. The vulnerability is caused due to a boundary error in AtomixMP3 when handling .M3U files. This can be exploited to cause a stack-based buffer overflow via a specially crafted .M3U file.
This module runs a malicious web server on the CORE IMPACT Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
