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.

This module exploits the nginx stream ssl_preread/SNI variant of CVE-2026-42533. A crafted TLS Server Name Indication triggers two-pass complex-value evaluation, allowing an unauthenticated attacker to disclose process addresses and corrupt the nginx worker heap. The module captures the leaked addresses, sprays a forged cleanup handler through the HTTP listener, and triggers the corruption through the stream listener to invoke system() in the nginx worker. It then downloads and executes a Core Impact Linux agent. The attack is layout-dependent and may interrupt the nginx worker.
GitLab Repository Commits API Path Traversal Arbitrary File Read Exploit
CVE-2026-85706 is an improper path confinement and missing authentication vulnerability in the GitLab repository commits API. A remote unauthenticated attacker can forge Workhorse body-upload metadata and make GitLab read an arbitrary local file before authentication is enforced. This module sends a crafted form to the repository commits API and extracts file content reflected by a parser error. The request does not require a GitLab account, but PROJECT ID must identify an existing project that is available to unauthenticated users.

Microsoft Configuration Manager CAB Extraction Remote Code Execution Exploit
The module authenticates to Configuration Manager AdminService with a low-privileged domain identity and calls UploadExtensionInChunks. The exploit uses an Authenticode-signed CAB to extract a path traversal to place an adsource.dll proxy and a preserved original DLL in the Configuration Manager bin X64 directory. Active Directory System Discovery subsequently loads the proxy in SMS_EXECUTIVE and modifies the built-in RID-500 account as NT AUTHORITY\\SYSTEM. The module then authenticates over SMB with that local administrator and deploys an Impact agent as SYSTEM.
Microsoft Windows Kerberos Improper Authorization ResetNightmare
ResetNightmare is an authorization flaw in the Microsoft Kerberos Change Password protocol. On an unpatched domain controller, an attacker who can write the userPrincipalName attribute of a controlled account can obtain a kadmin/changepw ticket whose client name identifies another account while its PAC identifies the controlled account. The module temporarily changes the controlled account's UPN to the target sAMAccountName, requests a kadmin/changepw ticket with an NT-ENTERPRISE client name, restores the original UPN, and uses the ticket in an RFC 3244 password-change exchange.

Linux Kernel VsockDrop Local Privilege Escalation Exploit
This module exploits CVE-2026-53365, to elevate privileges on a Linux target. The vulnerability is a page-reference-count underflow in the Linux kernel io_uring zero-copy send path over AF_VSOCK. It can free a page that remains pinned and allow the page to be reclaimed as privileged file page-cache data. The exploit uses the vulnerability to modify the interpreter path in the page-cache contents of "/usr/bin/su" and execute a caller-supplied ELF with root privileges.
Microsoft Windows Cross Device Service Elevation of Privilege Vulnerability Exploit
This module exploits CVE-2026-66804, an improper access control vulnerability in the Microsoft Windows Cross Device Service, to execute a CORE Impact agent with NT AUTHORITY\SYSTEM privileges. Windows registers the Cross Device virtual-camera COM server at PROGRAMDATA\CrossDevice\CrossDevice.Streaming.Source.dll. On affected systems, the machine-wide registration can exist while PROGRAMDATA\CrossDevice is absent and creatable by a standard user. An attacker can create that missing directory and plant the registered COM DLL.
Microsoft Windows Snipping Tool NTLM Information Disclosure Exploit
This module exploits an information disclosure vulnerability in Microsoft Windows Snipping Tool. A malicious web page invokes the ms-screensketch URI handler with an attacker-controlled UNC path. When the victim allows the browser to open Snipping Tool, the application connects to the SMB server and discloses the current user's Net-NTLM response. This exploit does not install an agent.
Microsoft Windows Win32k xxxInterceptSetWindowPos Elevation of Privilege Vulnerability Exploit
Microsoft Windows is vulnerable to a use-after-free in win32kfull!WindowActions::xxxInterceptSetWindowPos. The vulnerability can be triggered while processing deferred window-position operations for intercept windows, allowing freed kernel memory to be reclaimed with attacker-controlled allocations. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges.
This module exploits CVE-2026-63077, a pre-authentication unsafe XML deserialization vulnerability in JetBrains TeamCity On-Premises. It registers a synthetic build agent through the agent polling protocol and submits a crafted XML document using the resulting agent session, without requiring TeamCity user credentials. Deserialization of the payload initializes an in-memory HSQLDB data source and uses HSQLDB's SCRIPT functionality to write a temporary JSP payload into the TeamCity ROOT web application.

Microsoft Defender ShieldBreak Elevation of Privilege Vulnerability Exploit
This module exploits the ShieldBreak local privilege escalation vulnerability in Microsoft Defender to execute a Core Impact agent with SYSTEM privileges. ShieldBreak bypasses the fix for the RoguePlanet vulnerability (CVE-2026-50656). The exploit combines the Windows Cloud Files API, Object Manager shadow directories and symbolic links, the Common Log File System, and Defender's privileged remediation workflow to redirect a file operation into the native Windows System32 directory.
This module exploits CVE-2025-37164, an unauthenticated remote code execution vulnerability in HPE OneView. The module first queries the appliance version endpoint, then validates the vulnerability by sending a benign command to the ID Pools executeCommand REST endpoint. If the target is vulnerable, commands are executed through the same endpoint to deploy an OSCI agent or a classic network agent. The vulnerable endpoint does not return command output, so the OSCI agent is committed as a blind command execution primitive.

Microsoft Windows WalletService Elevation of Privilege Vulnerability Exploit (CVE-2026-49176)
This module exploits an elevation of privilege vulnerability in Windows WalletService to achieve arbitrary code execution with NT AUTHORITY\\SYSTEM privileges. The exploit performs the following steps: Prepares a controlled Wallet store containing a persisted callback. Temporarily redirects the current user's Documents known folder to the controlled store. Triggers WalletService through the Windows Wallet APIs. Starts a SYSTEM-level CORE Impact agent from the WalletService callback. Restores the original Documents known folder and removes temporary artifacts when possible.
This module uses a chain of a REST batch route-confusion combined with a SQL injection vulnerability to deploy a network agent in WordPress Core that will run with the same user privileges than the affected software. The module will use the vulnerability chain and perform the following steps: * Check if the target is vulnerable. If it's not, the attack will stop. * Query the current number of wp_posts rows whose type is oembed_cache. This is saved so cleanup can later verify the run restored the cache count.
