Open lesservehicle opened 2 years ago

lesservehicle commented 2 years ago

Description

Behind a corporate proxy, the Virustotal enrichment connector will fail

Environment

  1. OS: RedHat 7, on Docker 1.13.1

  2. OpenCTI version: 5

  3. OpenCTI client: Frontend

Reproducible Steps

Steps to create the smallest reproducible scenario:

Run the Virustotal enrichment connector behind a proxy that intercepts HTTPS

Expected Output

A successful connection to the Virustotal API

Actual Output

WARNING:urllib3.connectionpool:Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)'))': /api/v3/urls/aHR0cDovLzE3NS45OC4yMDAuMjoxOTYxNS8uaQ

ERROR:virustotal.client:[VirusTotal] Error connecting: HTTPSConnectionPool(host='www.virustotal.com', port=443): Max retries exceeded with url: /api/v3/urls/aHR0cDovLzE3NS45OC4yMDAuMjoxOTYxNS8uaQ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')))

ERROR:root:Error in message processing, reporting error to API

Additional information

The use of Certifi in connectors/internal-enrichment/virustotal/src/virustotal/client.py should rectify this issue, as it will allow the user to load a certificate chain.

Example: import certifi ... requests.get(url=url, cert=certifi.where())

Authorize self signed certificate in this connector, as a configuration parameter.
