This module exploits an elevation of privilege vulnerability in the Windows Cloud Files Mini Filter Driver (cldflt.sys) to achieve arbitrary code execution with SYSTEM privileges. The vulnerability resides in the HsmOsBlockPlaceholderAccess routine and abuses the Cloud Files abort hydration path to create attacker-controlled registry keys in the .DEFAULT user hive without proper access checks. MiniPlasma is the same issue previously tracked as CVE-2020-17103, which was reported by Google Project Zero and later claimed to be patched, but it remains exploitable on current Windows builds. The steps performed by the exploit are: Creates a controlled Cloud Files synchronization root and uses the abort hydration path to trigger the race condition. Redirects privileged registry key creation into the .DEFAULT user hive. Abuses the writable .DEFAULT Volatile Environment registry key to control the windir environment used by a SYSTEM process. Triggers the elevated process to launch a CORE Impact agent with SYSTEM privileges in the target user's interactive session.

A local unprivileged user can coerce "cupsd" into authenticating to an attacker-controlled localhost IPP service with a reusable "Authorization: Local" token. That token is enough to drive "/admin/" requests on "localhost", and the attacker can combine "CUPS-Create-Local-Printer" with "printer-is-shared=true" to persist a "file:///" queue even though the normal "FileDevice" policy rejects such URIs. Printing to that queue gives an arbitrary root file overwrite; allowing root command execution. This module uses the previous vulnerability to escalate privileges and deploy a new agent that will run with root user privileges. The module starts a local capture server on the port given by the CAPTURE_PORT parameter. If no parameter is provided, the module will use 9189 as the default port value. Also, the IPP port can be set with the IPP_PORT parameter. If no parameter is provided, the module will use 631 as the default port value. Then it will find and use the "ipptool" executable to trigger the local admin print to leak the auth token. The module will try to leak the token 5 times. Once the token is leaked, the module will create a temporary directory and upload the trigger and agent executables. Then it will locate the "sudo" and "whoami" executables and proceed to trigger the vulnerability to create a file inside the "/etc/sudoers.d/" directory that will allow the current user to use the "sudo" command without a password. If the attack succeeds, the agent will be executed via "sudo" which will deploy a new agent with root user privileges. Once the agent is deployed, the module will delete the trigger executable and the root file in the "/etc/sudoers.d/" directory.

This module exploits DirtyFrag, a local privilege escalation vulnerability chain in the Linux kernel that can corrupt cached pages of privileged files through kernel networking components. The trigger binary supports two exploitation paths. The ESP path temporarily corrupts the page-cache contents of "/usr/bin/su" with a small ELF launcher that executes a caller-supplied custom ELF as root. The rxrpc/rxkad path temporarily corrupts the page-cache contents of "/etc/passwd" to allow passwordless root authentication through "su" and then executes the supplied custom ELF. Before running either path, the trigger binary creates a temporary full backup of the target file it may corrupt. The ESP path restores "/usr/bin/su" from its backup after the patched "su" process is launched. The rxrpc/rxkad path restores "/etc/passwd" from its backup and removes that backup before handing execution to the custom ELF. The module uploads the DirtyFrag trigger binary and a generated Core Impact agent ELF with random names to the temporary directory given in the TMP_DIR parameter. If no parameter is provided, the module will use "/tmp" as the default value. The exploit is executed as the uploaded trigger binary with the uploaded agent path as its custom ELF argument. Once the attack is complete, a new Core Impact agent will be deployed on the target system with root user privileges. After the new agent connects, the module attempts to drop filesystem caches with the "sysctl" command and removes the uploaded trigger and agent binaries.

This module uses an incorrect 'in-place operation' vulnerability in the Linux kernel's algif_aead cryptographic algorithm interface by abusing the authencesn AEAD wrapper to deploy a network agent. The vulnerability will overwrite kernel's cached pages of a given SUID file. The module will upload a trigger binary for the vulnerability in the temporary directory given in the TMP_DIR parameter. If no parameter is provided, the module will use "/tmp" as the default value. The binary SUID file given in the TARGET_SUID_BINARY parameter will be used for the attack. If no parameter is provided, the module will use "/usr/bin/su" as the default value. Once the attack is complete a new Core Impact agent will be deployed in the target system that will run with root user privileges. Finally, the module will use the "sysctl" command to restore the cache.

This module exploits a Time-Of-Check Time-Of-Use (TOCTOU) race condition within the Windows Defender remediation process to achieve arbitrary code execution with SYSTEM privileges. The exploit chain leverages the Windows Cloud Files API (cfapi) and an EICAR test string to purposely pause the antivirus engine's remediation thread using a Batch Oplock. During this suspended state, the module uses NTFS mount points (directory junctions) to redirect the highly privileged antivirus file operations from a temporary directory to a protected system folder (C:\Windows\System32). When the oplock is released, the antivirus mistakenly overwrites a legitimate system binary (TieringEngineService.exe) during its cleanup routine. The module then replaces this corrupted binary with a malicious payload and triggers a specific COM object to start the service, yielding a SYSTEM agent. The steps performed by the exploit are: Creates a decoy executable containing a dynamically generated EICAR test string within a temporary directory to trigger an immediate antimalware response. Registers the temporary directory as a Cloud Sync Root and converts the decoy file into a cloud placeholder to intercept system interactions. Freezes the highly privileged antivirus remediation thread at a precise moment by requesting a Batch Oplock that trips when the engine scans the placeholder file. Executes a TOCTOU race condition by renaming the original directory and replacing it with an NTFS mount point targeting C:\Windows\System32. Releases the oplock, tricking the antivirus engine into blindly overwriting the target service binary (TieringEngineService.exe) as part of its automated threat remediation. Replaces the overwritten service binary with the exploit payload and invokes the Tiering Management Engine COM object to start the service as NT AUTHORITY\SYSTEM. Creates a named pipe to get the current session id and executes an interactive CORE Impact agent directly into the target user's desktop session.

This module exploits a Time-Of-Check Time-Of-Use (TOCTOU) race condition within the Windows Defender signature update mechanism to achieve arbitrary code execution with SYSTEM privileges. The exploit chain leverages Cloud Files oplocks and an EICAR synchronization trigger to purposefully freeze Windows Defender's I/O operations. During this paused state, the module uses NTFS directory junctions and Object Manager symbolic links to redirect Defender's file access from a legitimate signature update file to the locked SAM database within a Volume Shadow Copy (VSS). After reading the SAM hive into memory, the module performs offline AES/DES decryption to harvest local NTLM hashes. Finally, it uses the pass-the-hash technique to temporarily reset an administrator's password, creates a self-deleting Windows service, and injects an interactive SYSTEM-level agent directly into the target user's desktop session. The steps performed by the exploit are: Downloads the Windows Defender signature update and extracts the required files directly into memory to evade disk-based detection. Freezes Windows Defender's file input/output operations at a precise moment by chaining an EICAR test file trigger with Cloud Files oplocks. Captures the exact object namespace path of the temporary Volume Shadow Copy (VSS) generated during Defender's remediation workflow. Executes a TOCTOU race condition using an NTFS junction and Object Manager symlink to trick Defender into opening the locked SAM database instead of the signature file. Reads the SAM database contents into memory and utilizes offline AES and DES decryption to extract local NTLM hashes. Employs a pass-the-hash technique to temporarily alter an administrator password, registers a self-deleting service to achieve SYSTEM privileges, and injects a CORE Impact agent into the active user's desktop session.

ATBroker.exe (Windows Accessibility Infrastructure) resolves AT configuration from the per-user ATConfig path but performs unsafe file/registry operations. A registry symlink race condition in the ATConfig handling lets a local attacker write arbitrary values into protected HKLM keys and redirect the configuration load to a malicious AT entry, leading to arbitrary code execution as SYSTEM. The steps performed by the exploit are: Write target value to ATConfig registry path Set oplock on oskmenu.xml Lock workstation Wait for oplock (user interaction) Start target service (run agent as SYSTEM)

An authorization bypass vulnerability exists in the AsIO3.sys functionality of Asus Armoury Crate. A specially crafted hard link can lead to an authorization bypass. An attacker can create a hard link to trigger this vulnerability. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges. The steps performed by the exploit to elevate privileges are: Leak the address of the current thread Leak the address of the current process token Leak the address of the SYSTEM process token Trigger the vulnerability to bypass the authorization Abuse the driver to overwrite PreviousMode Replace the current process token with the SYSTEM token Restore original PreviousMode value
