Brigadier Fails at 7Zip Extraction #37

Open Mrjamin opened 5 years ago

Mrjamin commented 5 years ago

Hi,

Thanks for taking the time to develop this tool. I'm getting a failure at the point Brigadier is trying to extract the 7zip file. Here's the console ouput:

... Fetching Boot Camp product at URL http://swcdn.apple.com/content/downloads/39/14/031-55710/u2c6bi4yl91ud1lqc3k53bx9860hvsnf7z/BootCampESD.pkg.

Not sure if this is a bug or something with my system, so any thoughts would be greatly appreciated.

Thanks for reporting this issue. It also happens on my Windows 10.

To have it fixed, I have manually downloaded and installed 7zip in its default folder.

There's still a problem afterwards, but it could be worked around as you could see where the drivers were downloaded and invoke the install files yourself.

To the original issue, the logic for handling whether 7zip is installed correctly and is of proper version doesn't work correctly in some configurations. That could definitely get touched up.

The last time I built an installer for this was a couple of years ago, so take this with a grain of salt... The installer that Apple created only seems to work properly when run as SYSTEM (similar to root on macOS). When you try to execute the installer via setup.exe or by using msiexec, the install generally fails due to either timing out or some other error. I believe they did this because it was only intended to be run via the Bootcamp installer which installs it as part of the unattended setup of Windows.

At one point, I re-wrote this whole application as a Powershell script which created a scheduled task to run the setup.exe installer as SYSTEM. I had played with using PsExec, but some AV's were flagging it is a "hacking" tool... PsExec is obviously the easier one to test with and evaluate, so you could give that a try and see if that works better for you. I may be able to go back and find my last version of the script, but I haven't validated it in a couple of years since I moved into an InfoSec role.

I found out that brigadier works fine should it be started in an elevated command prompt. I guess only tech skilled people would try to fix their macbook drivers, so I would question whether any changes are needed at this point. Error messages are pretty clear on what the issue is and one could fix them with ease.

Maybe the prerequisites should be more clearer.

  1. Have 7zip installed.
  2. Run brigadier in an elevated shell.
bhaveshsood13 commented 2 years ago

So it doesn't work even after running in cmd with administrator rights having installed 7zip already . Though there is a workaround. All you need to do is go to c:\users\nickpe~1\appdata\local\temp\bootcamp-unpack_udazk8 wherever the 7-Zip command was called , and then there extract that pkg file with 7-Zip by right clicking and extract here with 7-Zip . After that open the file with 7-Zip and you'll be able to see the folders , then you can install the drivers as you want.

wild guess: maybe the downloaded file is not fully flushed to disk, so 7z sees an incomplete file? no, it really is a bug in 7z 23.01

mo-g commented 1 year ago

Just got a similar issue with a MacBook7,2 using latest release of Brig and a manually downloaded 7zip - on Windows 10; using the latest release .exe. Also ran as "SU" following advice in this thread, then tried manually downloading BootCampESD from the link in the CLI logs and extracting with 7z. Payload extraction also fails there.

Could this be a regression in 7z itself?

lstriegher commented 1 year ago

Yeah, it seems like a regression in 7z. The older version 7-Zip 19.00 (2019-02-21) worked fine for me, unlike the newest versions (Not sure about releases between the two).

I can confirm that this seems to be a 7zip issue. I get the same errors:

ERROR: Data Error : Windows6.1-KB2685811-x64.cab

And manually extracting the files with 7zip was unsuccessful as well, 7zip prompts ".... there's some data at the end of the archive ..." and extraction fails.

Uninstalling the latest 7zip 7-Zip 23.01 (2023-06-20) and installing the previous version 7-Zip 22.01 (2022-07-15) resolved the issue.

THANK YOU! jameswsullivan

we must have been working on this at the same time, because I can confirm this is a 7-zip 23.01 issue also. Immediately downgrading resolved this problem with the following error of:

ERROR: Data Error : Windows6.1-KB2685811-x64.cab
ERROR: Data Error : Windows6.1-KB2685811-x64-pkgProperties.txt
ERROR: Data Error : Windows6.1-KB2685811-x64.xml

I don't even use this account and I haven't logged in for years, this was one of those times where I had to login to say thank you so much for discovering this. This was driving me up the wall I was about to purchase a license for magic utilities because the trial is very nice and so easy, but now we can finally do something as simple as scroll with this magic mouse. xD

You are a life saver. I have 7zip 22.01 installed and I have placed to brigadier to my desktop. Navigated to my desktop while in command prompt (admin) and have successfully executed this command:

brigadier.exe -m MacBookPro14,1

Now I have all the files extracted into a bootcamp folder with all the files successfully extracted. Installed the AppleWirelessMouse64 in the BootCamp\Drivers\Apple directory, I don't even think i needed to restart. this is groundbreaking! I can confirm this works in windows 11 x64. Thank you again

alternative: peazip but that is a gui tool

so... either/or

to reduce disk writes, the 3 extraction steps should be done in memory

```sh du -sh * # 1.6G BootCampESD # 1.6G BootCampESD.pkg # 1.6G Payload # 2.6G WindowsSupport rm -rf BootCampESD Payload WindowsSupport mkdir WindowsSupport cd WindowsSupport cat ../BootCampESD.pkg | bsdtar -x -O Payload | bsdtar -x -O "Library/Application Support/BootCamp/WindowsSupport.dmg" | 7z x /dev/stdin # ERROR: /dev/stdin # Can not open the file as archive cd .. rm -rf WindowsSupport ``` 7z fails to extract from stdin, so at least 2 steps can be piped ```sh cat BootCampESD.pkg | bsdtar -x -O Payload | bsdtar -x "Library/Application Support/BootCamp/WindowsSupport.dmg" mkdir WindowsSupport cd WindowsSupport 7z x ../"Library/Application Support/BootCamp/WindowsSupport.dmg" cd .. ``` we also can pipe the http request ```sh curl -s http://swcdn.apple.com/content/downloads/62/58/041-98143-A_HN8B941A1T/nknv1gt3xcgylggwc11kl5e0j4296tjfo1/BootCampESD.pkg | bsdtar -x -O Payload | bsdtar -x "Library/Application Support/BootCamp/WindowsSupport.dmg" mkdir WindowsSupport cd WindowsSupport 7z x ../"Library/Application Support/BootCamp/WindowsSupport.dmg" cd .. ```
