If you need to, handoff the email to another working group member. Don’t forget to re-assign it to them.

What to do

Forward a report to an operator or Axim

If a report applies only to a particular operator or to Axim:

  1. Find the operator’s contact information at https://openedx.atlassian.net/wiki/spaces/COMM/pages/3624140816/Security+Working+Group+Private#Contacts

  2. “Forward” report to the operator from the Google Groups web interface

    1. Click on “Reply all” at the bottom of the email thread.

    2. Change sender to “security@openedx.org”

    3. Clear Cc: field to remove reporter’s email(s)

    4. Add operator’s email to Cc: field

    5. Change the subject prefix from “Re:” to “Fwd:”

    6. Check any relevant attachments are still included.

    7. Include a blurb, like below:

    8. Post message

  3. Reply all to the reporter’s original email so the email to the operator is not included in the thread.

    1. The Reply all button should look like the above and is to the right of the header of the reporter’s original email.

    2. Check the sender is still “security@openedx.org”

    3. Click on the … at the bottom of the draft to check other emails are not included in the reply.

    4. Include a blurb, like below:

Respond to a security disclosure

A security disclosure is someone emailing to report a security vulnerability in Open edX software.

Our job:

Give security advice

under construction

Process suggestions for security improvements

In our GitHub Project:

  1. Decide whether the suggestion is worth accepting.

    • If in doubt, create a ticket titled “Discuss […]”

  2. Consider whether the suggestion can be made public.

  3. Search for existing, similar suggestions.

  4. Create or comment on the issue for the suggestion.

    • Add a link to the Google Groups message

    • To add an issue:

      • Select “Convert to issue” and add the issue to the wg-security repo. [GitHub docs]

  5. Reply to the reporter:

  6. If a new issue, notify #wg-security:

Map a Name to a Github Username

It’s generally useful to be able to either map real names to GitHub usernames or map GitHub user names from a catalog-info.yaml file to real names so that we can contact maintainers via other communication channels (Email, slack, Discourse, etc.)

As a security manager you will have access to this mapping of names to Github usernames.

This is privileged information and the full document should not be shared with others. You should only be using it to help triage or resolve security incidents. For all other issues, seek help from the Axim Engineering team.

  1. Go to https://github.com/openedx/openedx-webhooks-data/blob/main/salesforce-export.csv

  2. Look up the name or GitHub username.
