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.

Simple Web Server GET Request Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of software utilizing Simple Web Server. The vulnerability is caused due to a boundary error within Simple Web Server when processing HTTP GET Request. This can be exploited to cause a stack-based buffer overflow via an overly long, specially-crafted argument passed to the affected command. Authentication is not required to exploit this vulnerability.
This module exploits a remote stack-based buffer overflow in Siemens Tecnomatix FactoryLink by sending a malformed packet to CSService listening on port 7580.

Impact
SIELCO SISTEMI Winlog Malformed Packet Stack Buffer Overflow Exploit
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of software utilizing SIELCO SISTEMI Winlog when Run TCP/IP server is enabled in CONFIGURATION-OPTIONS-TCP/IP. The vulnerability is caused due to a boundary error within SIELCO SISTEMI Winlog when processing a malformed request. This can be exploited to cause a stack-based buffer overflow in Runtime.exe via a crafted 0x02 opcode packet. Authentication is not required to exploit this vulnerability.
A weakness has been reported in WordPress which can be exploited to bypass certain security restrictions. The weakness is due to a bug within the password reset functionality when verifying the secret key. This can be exploited to reset the password of the first user without a key in the database (usually administrator) without providing the correct secret key.
Exploits / Authentication Weakness / Known Vulnerabilities
Impact
OpenSite Weak Authentication Exploit
This module exploits an authentication vulnerability in OpenSite 2.1. The function init in origin/libs/user.php checks for a matching origin_hash cookie. However, this cookie can be bruteforced in at most 2^32 tries for a known username. Actually, the number of attempts could be significantly reduced knowing that we do not have to check for time in the future, and long past. This works for OpenSite 2.1 and below. It has to be executed against the root directory of OpenSite.
Exploits / Authentication Weakness / Known Vulnerabilities
Impact
MyBB Privilege Escalation Exploit
A vulnerability has been reported in MyBB, which can be exploited by malicious users to conduct SQL injection attacks. Input passed via the "birthdayprivacy" parameter to inc/datahandlers/user.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. Successful exploitation requires a valid user account. The vulnerability is reported in MyBB 1.4.x versions prior to 1.4.7. This modules gives to a normal user, admin privileges.
Exploits / Authentication Weakness / Known Vulnerabilities
Impact
Serv-U chmod exploit
An internal memory buffer may be overrun while handling "site chmod" command with an overly long filename. This condition may be exploited by attackers to ultimately execute instructions with the privileges of the serv-u process, typically administrator or system. This bug requires the FTP user to have write privileges on at least one directory to be exploited. The Serv-U server will be left inaccessible after successful exploitation.
Serv-U supports an FTP command, "MDTM", which is used to change a file's modification time. An internal memory buffer may be overrun while handling an malformed time zone as MDTM argument. This condition may be exploited by attackers to ultimately execute instructions with the privileges of the serv-u process, typically administrator or system. The Serv-U server will be left inaccessible after successful exploitation.
Exploits a vulnerability in the Real VNC server to bypass the password authentication. A compatible VNC client is required. This exploit proxies TCP connections to a remote (or local) VNC server and monitors the list of supported authentication methods of the server. Connecting clients will receive a dummy list consisting of only one authentication method (no password). Unlike other exploits, this module does not deploy any agents.
POODLE TLS1.x to SSLv3 Downgrading Vulnerability Exploit
Before using this module please consider that this is not an actual one-step exploit but a tool that allows our community to confirm if a target infrastructure is vulnerable to Poodle attack by executing a PoC (Proof of Concept). This module is not meant to be used against a victim like most Impact exploits are. Further, to just scan your network for weak ciphers, see the "Test SSL Ciphers" in Impact's Web tab.
The SSL protocol, as used in Oracle Java, encrypts data by using CBC mode with chained initialization vectors. This weakness allows to decrypt HTTP headers by a chosen plain text attack, thus obtaining browser cookies from the target system's browser corresponding to a given HTTPS server. The cookies could then be used by the user to do a session hijacking attack. This module launches the attack against target systems. This systems must be running a browser with the vulnerable Java version for this exploit to work.
Microsoft Windows LNK Shortcut Automatic DLL Loading Exploit (MS15-020)
Microsoft Windows is prone to a vulnerability that may allow a DLL file to be automatically loaded because the software fails to handle LNK files properly. Specifically, the issue occurs when loading the icon of a shortcut file. A specially crafted LNK file can cause Windows to automatically execute code that is specified by the shortcut file. The attacker must entice a victim into viewing a specially crafted shortcut. The shortcut file and the associated binary may be delivered to a user through removable drives. An attacker may exploit this issue to execute arbitrary code.
SIDVault LDAP Server Remote Buffer Overflow Exploit
This module exploits a buffer overflow vulnerability in the LDAP service (sidvault.exe) of the SIDVault LDAP application. The exploit triggers a stack-based buffer overflow by sending a specially crafted packet to port 389/TCP of the vulnerable system and installs an agent if successful.
This module attacks default XAMPP installations and abuses the use of default credentials for webdav. The module can also be configured to take advantage of user supplied credentials.
