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.

Product Name
Microsoft Windows Networks File System 4.1 Remote DoS
Microsoft Windows could allow a remote attacker to execute arbitrary code or BSOD the system, caused by a design flaw in the Network File System component.
Linux Kernel Netfilter Dup Netdev OOB Write Local Privilege Escalation Exploit
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges because of a heap out-of-bounds write. This is related to nf_tables_offload.
A vulnerability was discovered in RealVNC VNC Server installations on Windows when running MSI repair, which can lead to a local user privilege escalation.
Linux Kernel eBPF OR NULL Pointer Local Privilege Escalation Exploit
The bpf verifier(kernel/bpf/verifier.c) did not properly restrict several *_OR_NULL pointer types which allows these types to do pointer arithmetic. An unprivileged user could use this flaw to escalate their privileges on a system. Setting parameter "kernel.unprivileged_bpf_disabled=1" prevents such privilege escalation by restricting access to bpf(2) call.
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.
Microsoft Windows Support Diagnostic Tool (MSDT) Remote Code Execution Exploit
This module exploits a vulnerability in Microsoft MSDT, which can be leveraged to execute arbitrary code on vulnerable machines by convincing an unsuspecting user to open a malicious document.
This update adds a new parameter to the "Ransomware Simulation" module: "RENAME FILES"; if set to TRUE, encrypted files will also be renamed by adding the .1mp4ct extension to them.
Microsoft Windows Point-to-Point Tunneling Protocol DoS
A denial of service vulnerability exists in Point-to-Point Tunneling Protocol service when an unauthenticated attacker connects to the target system and sends specially crafted requests.
This update adds a couple modules to simulate a ransomware attack in a previously exploited host. "Ransomware Simulation" to run the simulated ransomware attack. "Files Decryption after Ransomware Simulation" to decrypt previously encrypted files.

Impact
Spring Framework Spring4Shell Remote Code Execution Exploit
An unsafe data binding used to populate an object from request parameters (either query parameters or form data) to set a Tomcat specific ClassLoader in Spring MVC and Spring WebFlux applications allows unauthenticated attackers to upload and execute a JSP file in the Tomcat virtual file system webapps directory.
A deserialization vulnerability present in the OpenssoEngineController component of Oracle Access Manager allows a unauthenticated attacker with network access via HTTP to execute system commands.
Linux Kernel watch_queue Local Privilege Escalation Exploit
An out-of-bounds (OOB) memory write flaw was found in the Linux kernel's watch_queue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system.
Veeam Backup and Replication ExecuteUploadManagerPerformUpload Remote Code Execution Exploit
An authentication bypass in Veeam.Backup.ServiceLib.CForeignInvokerNegotiateAuthenticator.Authenticate and a file upload present in ExecuteUploadManagerPerformUpload allows an unauthenticated attacker to execute system commands with the privileges of the "IIS Worker Process" process (NT AUTHORITY\\NETWORK SERVICE)
This bug could allow an attacker to gain code execution on an affected system by sending specially crafted packets to a system utilizing the HTTP Protocol Stack (http.sys) to process packets. No user interaction, no privileges required, and an elevated service add up to a wormable bug. And while this is definitely more server-centric, remember that Windows clients can also run http.sys, so all affected versions are affected by this bug. Test and deploy this patch quickly.
Apache James Log4shell Remote Code Execution Vulnerability Exploit
Description: JNDI features used in configuration, log messages, and parameters present in Apache Log4j2 do not protect against attacker controlled LDAP and other JNDI related endpoints. This library, used by Apache James, allows unauthenticated attackers to execute system commands.
Linux Kernel Dirty Pipe Local Privilege Escalation Exploit
Improper initialization of the flags member of the pipe buffer structure in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel, could allow an unprivileged local user to write to pages in the page cache backed by read-only files and escalate privileges on the system.
Microsoft Windows Print Spooler Elevation of Privilege Vulnerability Exploit (CVE-2022-21999)
An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly allows arbitrary writing to the file system. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
JNDI features used in configuration, log messages, and parameters present in Apache Log4j2 do not protect against attacker controlled LDAP and other JNDI related endpoints. This library, used by VMware Horizon Connection Server, allows unauthenticated attackers to execute system commands.
