TheHive: StreamSrv 504 Gateway

TheHive relies on a long polling stream API. Nginx config must include proxy timeout setting. See more. You can find the recommended config here

server {
    listen 443 ssl;
    server_name thehive.example.com;

    ssl_certificate ssl / thehive_cert.pem;
    ssl_certificate_key ssl / thehive_key.pem;

    proxy_connect_timeout 600;
    proxy_send_timeout 600;
    proxy_read_timeout 600;
    send_timeout 600;
    client_max_body_size 2 G;
    proxy_buffering off;
    client_header_buffer_size 8 k;

    location / {
        add_header Strict - Transport - Security "max-age=31536000; includeSubDomains";
        proxy_pass http: //127.0.0.1:9000/;
            proxy_http_version 1.1;
        proxy_set_header Connection "";# cf.https: //github.com/akka/akka/issues/19542
    }
}

MISP: exec user process caused "no such file or directory"

This would be happened due to format of run.sh on pe3zx/misp-docker is incorrect. Make sure EOL of run.sh file is Unix-style. You can change EOL on the file with dos2unix like this:

dos2unix run.sh

TheHive and Cortex: Missing connectors/analyzers/responders

On hardened environment, permissions of mounted volumes are strictly controlled, for example by option like noexec. This control may cause issues on connectors/analyzers/responders loading. New permissions must be assigned to make the loading process works.

One of issues discovered on TheHive causes connectors.misp.MispConnect failed to load and no errors are provided:

In this situation, verify that the permission of /etc/thehive/application.conf and make sure that the file is configured to be read by anyone.

chmod +r application.conf

Another issue discovered on Cortex causes the platform failed to load contents on /opt/Cortex-Analyzers/. In this situation, I fix by remounting the partition with exec and assign 777 permission to ./apps/Cortex-Analyzers/ recursively.

TheHive and Cortex: Services started before Elasticsearch is ready

In some case, the Elasticsearch service may not ready yet which resulting as errors on TheHive and Cortex service:

cortex_1         | [info] o.t.c.s.ErrorHandler - GET /api/user/current returned 520
cortex_1         | org.elasticsearch.transport.RemoteTransportException: [KBrQQVH][172.16.0.9:9300][indices:data/read/search]
cortex_1         | Caused by: org.elasticsearch.index.IndexNotFoundException: no such index

You can try examining logs from the Elasticsearch service to see if the service is ready or not. If the Elasticsearch service is ready, try restarting both TheHive and Cortex service would resolve the connection issues.
