Audit CouchDB - The Simple, Clear, CouchDB Security Assessment

Tuesday, February 23, 2016

Audit CouchDB is a simple tool with a powerful message. Given an Apache CouchDB URL, it will tell you everything you ever wanted to know about its security.

Audit CouchDB will perform the following actions:
  1. Learn every possible fact about the couch, for example:
    • What is the server configuration?
    • What user accounts exist?
    • What user roles exist?
    • What databases exist?
    • In each database, what is the security setting?
    • In each design document, what are the validation functions?
  2. Given the facts, compare them against each other and warn if they imply a security concern, for example:
    • You obviously didn't bother to click the "Security" link in the database page in Futon
    • Published CVE alerts apply to your version of CouchDB
    • A design document is missing a validate_doc_update function
    • Helpful summaries of how many admins, normal users, and anonymous users can access each database

Currently, Audit CouchDB is a Node application distributed via NPM. Install it (globally) via npm .
npm install -g audit_couchdb
Next, run the tool with your CouchDB URL as a parameter. You should connect as an admin user, so Audit CouchDB can fetch all possible information (such as the configuration).
audit_couchdb https://admin:secret@localhost:5984
The tool will output everything it knows about your couch's security.
To see how audit_couchdb is working, set its log level to debug. It will show you each query it makes as it learns facts about your couch.
audit_couchdb --level=debug https://admin:secret@localhost:5984

Running from the Browser
Audit CouchDB is implemented as a library, depending on a back-end request library, and a front-end to display the output (simple console text output, or log4j if it is installed).
I recently re-implemented request in the browser as jQuery Request . Thus I am excited to see Audit CouchDB run on the browser, however I have not begun this work.
