Summary
Dragonfly's manager makes requests to external endpoints with disabled TLS authentication
Details

Impact

The Manager disables TLS certificate verification in two HTTP clients (figures 3.1 and 3.2). The clients are not configurable, so users have no way to re-enable the verification.

func getAuthToken(ctx context.Context, header http.Header) (string, error) { [skipped]
       client := &http.Client{
             Timeout: defaultHTTPRequesttimeout,
             Transport: &http.Transport{
                    TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
             },
}
[skipped]
}

A Manager processes dozens of preheat jobs. An adversary performs a network-level Man-in-the-Middle attack, providing invalid data to the Manager. The Manager preheats with the wrong data, which later causes a denial of service and file integrity problems.

Patches

Workarounds
