[import-document,import-file-stix] Support running as an arbitrary user (OpenShift Container Platform)

[leitosama]

Description

All connectors and OpenCTI Platform are deployed in OpenShift Container Platform.

• import-document connector returns PermissionError: [Errno 13] Permission denied: '<file>' error while downloading into container filesystem
• import-file-stix connector returns PermissionError: [Errno 13] Permission denied: '/.stixmarx' while starting up
  This error occurs because OCP runs container using an arbitrarily assigned user ID (same as Support running as an arbitrary user (OpenShift Container Platform) opencti#4885).

Environment

1. OS (where OpenCTI server runs): Red Hat CoreOS 9(OpenShift Container Platform)/Debian 11 (docker compose)
2. OpenCTI version: 6.2.13
3. OpenCTI client: non applicable
4. Other environment details:

Reproducible Steps

To reproduce this error in Docker:

1. Change docker-compose.yml in OpenCTI Docker):

  connector-import-document:
    image: opencti/connector-import-document:6.2.13
    user: 1005:0

2. Run OpenCTI Platform
3. Import a document or text using "Import" page http://localhost:8080/dashboard/data/import

Expected Output

Import is successful

Actual Output

The connector returns PermissionError: [Errno 13] Permission denied: '<file>'

I'm sorry, but PR #2508 does not fully resolve the bug related to the import-file-stix image.

This connector relies on the mitre/stixmarx repository, which still has an open Issue mitre/stixmarx#13 about ~/.stixmark

According to the stixmarx code, the connector attempts to create a file in the home directory (~).

I believe this can be fixed by passing the $HOME environment variable in the Dockerfile.
I will send new PR with fix later.
