If that script isn’t working, I’d probably look at setting the permissions manually. What are they set to now?

Hello Seph, Yes, I do it. But I can't modify permissions for ALL APPLICATIONS PACKAGES, it have special permissions.

I am by no means a windows expert.
2:39 PM
But I’d start by looking at the permissions, and trying to manually correct them.
2:39 PM
What are the permissions there?

I try to remove write and delete permisions but it doesn't work. They are:+ Show folder/read data. + Read extended attributes. + Write extended attributes. + Delete. + Read permissions.

From a powershell window, can you run
icacls.exe
with the directory osquery is in?

Can you runn that against the directory, not the binary?
3:06 PM
from there
icacls.exe .
should work
3:08 PM
I’m trying to read docs about what this is, and whether or not it’s possible to remove that permission grant
3:09 PM
What version of windows is this?

Windows Server 2019

It doesn't work. I think this group is used to can execute the programs. And the permissions could be correct. But I don't know why it fails.

seph

10/29/2019, 3:11 PM
That group has write access. osquery doesn’t like that.
3:13 PM
You can either remove the write access, or run osquery with
--allow_unsafe
flag. I’m less sure whether this represents an osquery bug.

I removed it and it does't work

seph

10/29/2019, 3:14 PM
Removed what? The permissions? What do you mean didn’t work? Windows doesn’t support removing it?

Eva

10/29/2019, 3:16 PM
I removed write permissions and osquery report the same error

seph

10/29/2019, 3:16 PM
does icacls.exe show the permissions as gone?
3:19 PM
I’ve copied this information into https://github.com/osquery/osquery/issues/5965 Hopefully more windows oriented people can take a look

Eva

10/29/2019, 3:22 PM
okay, Thanks! And yes, without write permission also doesn't work

seph

10/29/2019, 3:23 PM

Thank you. Those permissions seem to match the docs
