snap uses a seccomp filter to prevent the use of the TIOCSTI ioctl; in the
source code, this filter is expressed as follows:
# TIOCSTI allows for faking input (man tty_ioctl)
# TODO: this should be scaled back even more
ioctl - !TIOCSTI
In the X86-64 version of the compiled seccomp filter, this results in the
following BPF bytecode:
[...]
0139 if nr == 0x00000010: [true +0, false +3]
013b if args[1].high != 0x00000000: [true +205, false +0] -> ret ALLOW (syscalls: ioctl)
0299 if args[1].low == 0x00005412: [true +111, false +112] -> ret ERRNO
030a ret ALLOW (syscalls: ioctl)
[...]
This bytecode performs a 64-bit comparison; however, the syscall entry point for
ioctl() is defined with a 32-bit command argument in the kernel:
SYSCALL_DEFINE3(ioctl, unsigned int, fd, unsigned int, cmd, unsigned long, arg)
{
return ksys_ioctl(fd, cmd, arg);
}
This means that setting a bit in the high half of the command parameter will
circumvent the seccomp filter while being ignored by the kernel.
This can be tested as follows on Ubuntu 18.04. You might have to launch the
GNOME calculator once first to create the snap directory hierarchy, I'm not
sure.

# Exploit: X-NetStat Pro 5.63 - Local Buffer Overflow (EggHunter) #
# Date: 2019-03-23 #
# Author: Peyman Forouzan #
# Tested Against: Winxp SP2 32-64 bit - Win7 Enterprise SP1 32-64 bit - Win10 Enterprise 32-64 bit #
# Vendor Homepage: https://freshsoftware.com #
# Software Download : https://www.freshsoftware.com/files/xns56p_setup.exe #
# Version: 5.63 #
# Special Thanks to my wife #
# The program has Local Buffer Overflow in several places. #
# Note: Although there are even more simple codes to this vulnerability, #
# this technique (EggHunter) has been used to run vulnerability in different windows versions. #
# Steps : #
# 1- Run python code : X-NetStat.py ( Three files are created ) #
# 2- App --> Tools --> HTTP Client --> paste in contents from the egg.txt into "URL" #
# --> Enter --> Close HTTP Client window. #
# 3- Rules --> Add New Rule --> Actions --> paste in contents from the egghunter-winxp-win7.txt #
# or egghunter-win10.txt (depend on your windows version) into "Run Program" --> Ok #
# --> Wait a litle --> Shellcode (Calc) open #
# Also Instead of the third stage you can : #
# File --> Import / Resolve bulk IP List ... --> paste in contents from the egghunter-winxp-win7.txt #
# or egghunter-win10.txt (depend on your windows version) into "IP List (One IP per Line)" --> #
# Then Press Open file (Folder) Icon --> Wait a litle --> Shellcode (Calc) open #
#---------------------------------------------------------------------------------------------------------#
# "Egg" shellcode into memory --> Egghunter field overflow: EIP overwrite #
#---------------------------------------------------------------------------------------------------------#

VMware: Host VMX Process Impersonation Hijack EoP
Platform: VMware Workstation Windows v14.1.5 (on Windows 10). Also tested VMware Player 15.0.2.
Class: Elevation of Privilege
Summary: The creation of the VMX process on a Windows host can be hijacked leading to elevation of privilege.
Description: The VMX process (vmware-vmx.exe) process configures and hosts an instance of VM. As is common with desktop virtualization platforms the VM host usually has privileged access into the OS such as mapping physical memory which represents a security risk. To mitigate this the VMX process is created with an elevated integrity level by the authentication daemon (vmware-authd.exe) which runs at SYSTEM. This prevents a non-administrator user opening the process and abusing its elevated access.
Unfortunately the process is created as the desktop user and follows the common pattern of impersonating the user while calling CreateProcessAsUser. This is an issue as the user has the ability to replace any drive letter for themselves, which allows a non-admin user to hijack the path to the VMX executable, allowing the user to get arbitrary code running as a “trusted” VMX process. While having an elevated integrity level isn’t especially dangerous, the fact that arbitrary code is running as a “trusted” VMX process means you can access all the facilities for setting up VMs, such as the “opensecurable” command which allows the process to open almost any file as SYSTEM for arbitrary read/write access which could easily be used to get administrator privileges. Write file write access you could perform an attack similar to https://googleprojectzero.blogspot.com/2018/04/windows-exploitation-tricks-exploiting.html.
I reported the technique of hijacking process creation to Microsoft over 3 years ago (see https://bugs.chromium.org/p/project-zero/issues/detail?id=351). Unfortunately Microsoft declined to fix it at the time. This makes fixing this issue more difficult than it should be. You might think a a quick fix would be to not impersonate the user over the call to CreateProcessAsUser. However you can end up with other issues such as (https://bugs.chromium.org/p/project-zero/issues/detail?id=692). Also even if the user didn’t hijack the main process creation they could instead hijack DLL’s loaded by the VMX process once started.
A more comprehensive fix would to not create the process as the desktop user, instead using another user identity, however that in itself has risks and makes things considerably more complex.
Proof of Concept:
I’ve provided a PoC as a C#/C++ project. The C# application will perform the hijack and get the C++ vmware-vmx process
1) Compile the project. It will need to grab the NtApiDotNet from NuGet to work.
2) Ensure the compiled output directory has the files HijackVMXProcess.exe, NtApiDotNet.dll and vmware-vmx.exe.
3) Run HijackVMXProcess.exe. If successful you should find that instead of the installed version of vmware-vmx the fake one is running. You can also specify a path to HijackVMXProcess and the fake vmware-vmx will demonstrate opening the file using the opensecurable command for write access.
Expected Result:
The VMX process created is the version provided by VMWare.
Observed Result:
The VMX process is a fake one provided by the PoC which allows access to secured commands.

VMware: Host VMX Process COM Class Hijack EoP
Platform: VMware Workstation Windows v14.1.5 (on Windows 10). Also tested VMware Player 15.
Class: Elevation of Privilege
Summary: COM classes used by the VMX process on a Windows host can be hijacked leading to elevation of privilege.
Description: The VMX process (vmware-vmx.exe) process configures and hosts an instance of VM. As is common with desktop virtualization platforms the VM host usually has privileged access into the OS such as mapping physical memory which represents a security risk. To mitigate this the VMX process is created with an elevated integrity level by the authentication daemon (vmware-authd.exe) which runs at SYSTEM. This prevents a non-administrator user opening the process and abusing its elevated access.
Unfortunately the process is created as the desktop user which results in the elevated process sharing resources such as COM registrations with the normal user who can modify the registry to force an arbitrary DLL to be loaded into the VMX process.
The COM classes observed to be loaded by the VMX process, and thus can be hijacked by modifying the registry are as follows:
1b1cad8c-2dab-11d2-b604-00104b703efd Microsoft WBEM (non)Standard Marshaling for IEnumWbemClassObject
7c857801-7381-11cf-884d-00aa004b2e24 PSFactoryBuffer
8bc3f05e-d86b-11d0-a075-00c04fb68820 Windows Management and Instrumentation
bcde0395-e52f-467c-8e3d-c4579291692e MMDeviceEnumerator class
cb8555cc-9128-11d1-ad9b-00c04fd8fdff WbemAdministrativeLocator Class
d68af00a-29cb-43fa-8504-ce99a996d9ea Microsoft WBEM (non)Standard Marshaling for IWbemServices
e7d35cfa-348b-485e-b524-252725d697ca PSFactoryBuffer
The majority of these are related to WMI and are probably not critical so could be removed, however MMDeviceEnumerator is used to find audio devices which is probably important. Also note that hijacking COM classes isn’t necessarily the only resource which could be hijacked. From a fixing perspective I don't know of any documented way of preventing the lookup of COM classes from HKEY_CURRENT_USER other than running the process as an administrator, about all you can do is not use COM at all. As with the other bug I’ve reported at the same time a more comprehensive fix would probably to not create the process as the desktop user, instead using another user identity, however that in itself has risks.
Proof of Concept:
I’ve provided a PoC as a C++ project.
1) Compile the project, make sure to compile the x64 version of the DLL otherwise the PoC will fail.
2) Copy the compiled HijackDll.dll to the folder c:\hijack.
3) Install the hijack.reg file using REGEDIT or the command line REG tool. This setups up a hijack of the CB8555CC-9128-11D1-AD9B-00C04FD8FDFF class.
4) Start a VMX instance using the normal GUI or vmrun.
Expected Result:
The system COM class is loaded into the VMX.
Observed Result:
The VMX process loads the hijack DLL into memory and a dialog box appears proving the code injection.

A file with the .reg file extension is a Registration file used by the Windows registry. These files can contain hives, keys, and values.
.reg files can be created from scratch in a text editor or can be produced by the Windows registry when backing up parts of the registry.
[Vulnerability Type]
Windows .Reg File Dialog Box Message Spoofing
[CVE Reference]
N/A
[Security Issue]
The Windows registry editor allows specially crafted .reg filenames to spoof the default registry dialog warning box presented to an end user.
This can potentially trick unsavvy users into choosing the wrong selection shown on the dialog box. Furthermore, we can deny the registry editor
its ability to show the default secondary status dialog box (Win 10), thereby hiding the fact that our attack was successful.
Normally when a user opens a .reg file UAC will launch (if user is run as Admin) if targeting a non privleged user we can still hijack HKCU reg settings
without having to deal with UAC. After they will get the registry security warning dialog box asking them if they "trust the source" and
"Are you sure you want to continue?" etc and will also have a choice of either 'Yes' or 'No' to select from.
However, we can inject our own messages thru the filename to direct the user to wrongly click "Yes", as the expected "Are you sure you want to continue?"
dialog box message is under our control. The registry dialog echoes back the filename plus any text we add and allows us to terminate part of its
default security warning message. We achieve this using % encoded characters in the filename like %n or %r and %0.
Example, the "do not add it to the registry" and "Are you sure you want to continue?" default warning messages can be done away with using %0.
This spoofing flaw lets us spoof the "Are you sure you want to continue?" warning message to instead read "Click Yes" or whatever else we like.
Potentially making a user think they are cancelling the registry import as the security warning dialog box is now lying to them.
Denial of secondary registry editor status dialog box (hiding successful attacks) in Windows 10:
------------------------------------------------------------------------------------------------
Typically, upon a successful import the registry editor pops up another dialog box with a status message telling us
"the keys and values contained in <REGFILE> have been successfully added to the registry".
We can obstruct that behavior to deny this secondary registry editor dialog from appearing by tacking on a (null) right before the
end of our filename using %1 or %25 like: "Microsoft-Security-Update-v1.2-Windows-10.r%e%g%r%nC%l%i%c%k%b%Y%e%s%b%b%b%1%0.reg"
If don't want to use (null) use %3 but it will display a asian char instead but still prevents the secondary registry dialog box you.
You will have to manually refresh the registry written to in order to see the values stored when using these dialog denial of service methods.
Note: Denial of the secondary dialog box seems to only work on Windows 10.
Behaviors I discovered playing with registry filenames that affect the dialog box, depending on Windows OS version you will get different results.
% - can be used for obfuscation e.g. %h%a%t%e = hate
%b will create white-space
%n makes a newline
%r makes a newline
%1 creates (null) - important as we prevent the second registry dialog from appearing after a successful import!
%0 Important terminates string
%25 (Windows 10) creates (null) - Important as we prevent the second registry dialog from appearing after a successful import!
%3 - Important as we prevent the second registry dialog from appearing after a successful import! (but shows asian char)
%5 (Windows 10) duplicates the default registry dialog box message by "n" amount of times per amount of %5 injected into the filename
%25 (Windows 7) duplicates the default registry dialog box message by "n" amount of times per amount of %25 injected into the filename
%2525 prevents registry editor from opening
%169 will show our junky filename in the dialog box (we don't want that)
%3, %197, %17 and some others change the default language shown in the registry dialog box to asian characters etc
Each injected character can be separated by a percent "%" sign without messing up our spoofed message, we can leverage this to obfuscate the end of the filename.
We then use %0 to terminate the message string so that the second .reg extension and default registry messages are not displayed in the registry dialog box.
The filename "Microsoft-Security-Update-v1.2-Windows-10.r%e%g%r%nC%l%i%c%k%b%Y%e%s%b%b%b%1%0.reg" will show as "Microsoft-Security-Update-v1.2-Windows-10.reg"
in the registry dialog box, along with our spoofed user directions.
While this spoofing vulnerability requires user interaction and bypassing Windows UAC (if targeting Admin) prompt to succeed, the fact the we can prevent secondary
registry dialogs and modify registry messages displayed to the user makes it a viable attack vector. If we are successful in our attack we can achieve a persistent
RCE backdoor all while the user thinks they have aborted the import. Moreover, targeting a non privileged user allows us to hijack programs and not worry about UAC.

# Exploit Title: Core FTP 2.0 build 653 - 'PBSZ' - Unauthenticated - Denial of Service (PoC)
# Date: 2019-03-12
# Exploit Author: Hodorsec (hodorsec@protonmail.com / hodor@hodorsec.com)
# Vendor Homepage: http://www.coreftp.com/
# Software Link: http://coreftp.com/server/download/archive/CoreFTPServer653.exe
# Version: Version 2.0, build 653, 32-bit
# Tested on: Windows 8.1 6.3 (build 9600)
# CVE: N/A
# Description:
# CoreFTP 2.0 is vulnerable to a DoS attack via the PBSZ command. Ironically, this command is being used for "Protection Buffer Size"
# and CoreFTP responds unauthenticated.
# The PBSZ command in CoreFTP only allows for a certain length of the string to be vulnerable to a DoS.
# This script triggers the DoS and filling ECX with the intented buffer.
# Although NSEH/SEH is overwritten, the executable binary is SafeSEH protected and no other assemblies are referenced.
# Replication:
# - Install CoreFTP and setup a domain with an IP and path
# - Start the service or click "Start"
# - No need to add users or set anything specific: just run the script and watch it crash
# Crash as service:
# (7e0.bf4): Access violation - code c0000005 (first chance)
# First chance exceptions are reported before any exception handling.
# This exception may be expected and handled.

# Version: Windows 7 SP1, Server 2008, Server 2012, Server 2012 R2, 8.0, 8.1, 10 (any) with full patches up to December 2018. both x86 and x64 architectures.

# CVE : CVE-2019-0541
The Microsoft Windows MSHTML Engine is prone to a vulnerability that allows attackers to execute arbitrary code on vulnerable systems because of improper validation
of specially crafted web documents (html, xhtml, etc). The issue is triggered when users "Edit" specially crafted documents containing a 'meta' HTML tag set to 'ProgId' and its content set to a 'ProgId' of choice eg. 'HTAFILE', usually through MS IE browser or a MS Office
component (The Edit HTML app 'msohtmed.exe'). Some Office versions will add an "Edit" menu option to html and xhtml files, making it possible to exploit the vulnerability locally or remotely (usually through network shares)
This is the 'ProgId' exploit: Similar to the old Windows Shell / Internet Explorer ClassId vulnerabilit(ies) that haunted Windows 98/2000/XP in the past.'.
On patched systems, the PoC file will always open in Notepad.

'Name' => 'elFinder PHP Connector exiftran Command Injection',
'Description' => %q{
This module exploits a command injection vulnerability in elFinder
versions prior to 2.1.48.
The PHP connector component allows unauthenticated users to upload
files and perform file modification operations, such as resizing and
rotation of an image. The file name of uploaded files is not validated,
allowing shell metacharacters.
When performing image operations on JPEG files, the filename is passed
to the `exiftran` utility without appropriate sanitization, causing
shell commands in the file name to be executed, resulting in remote
command injection as the web server user.
The PHP connector is not enabled by default.
The system must have `exiftran` installed and in `$PATH`.
This module has been tested successfully on elFinder versions 2.1.47,
2.1.20 and 2.1.16 on Ubuntu.
