Mitigation Strategies Analysis for apache/couchdb

Mitigation Strategy: Disable "Admin Party"

1. Disable "Admin Party"

  • Mitigation Strategy: Disable "Admin Party"

  • Description:

    1. Edit CouchDB Configuration: Access the local.ini or default.ini configuration file.
    2. Modify [admins] Section: Remove or comment out any default usernames and passwords in the [admins] section. Optionally, set up initial admin user credentials if needed using secure methods.
    3. Restart CouchDB: Apply changes by restarting the CouchDB service.

  • List of Threats Mitigated:

    • Unauthorized Administrative Access (High Severity): Prevents default, unauthenticated administrative access to CouchDB.

  • Impact:

    • Unauthorized Administrative Access: High Risk Reduction

  • Currently Implemented:

    • Yes, implemented in couchdb.ini within deployment scripts. Default admin credentials are removed.

  • Missing Implementation:

    • N/A - Implemented across all environments.

Mitigation Strategy: Implement Role-Based Access Control (RBAC)

2. Implement Role-Based Access Control (RBAC)

  • Mitigation Strategy: Implement Role-Based Access Control (RBAC)

  • Description:

    1. Define Roles: Determine necessary user roles and their required permissions within CouchDB (e.g., read-only, write access to specific databases).
    2. Configure CouchDB Security: Utilize CouchDB's security features (security objects, validate_doc_update in design documents) to define and enforce these roles. Manage roles via CouchDB API or tools.
    3. Assign Roles to Users: Assign appropriate roles to CouchDB users, either directly or through external authentication integration.
    4. Enforce Permissions: Configure CouchDB security settings to actively enforce defined roles for data access and operations.
    5. Regular Review: Periodically review and update roles and permissions.

  • List of Threats Mitigated:

    • Unauthorized Data Access (Medium to High Severity): Restricts data access to authorized users based on their roles.
    • Privilege Escalation (Medium Severity): Limits users to their intended access levels.
    • Data Breaches due to Insider Threats (Medium Severity): Reduces potential damage from compromised internal accounts by limiting access.

  • Impact:

    • Unauthorized Data Access: High Risk Reduction
    • Privilege Escalation: Medium Risk Reduction
    • Data Breaches due to Insider Threats: Medium Risk Reduction

  • Currently Implemented:

    • Partially implemented. Database-level RBAC using CouchDB security objects is in place in production.

  • Missing Implementation:

    • Document-level RBAC using validate_doc_update functions is not fully implemented for fine-grained control within databases.

Mitigation Strategy: Enforce HTTPS/TLS

3. Enforce HTTPS/TLS

  • Mitigation Strategy: Enforce HTTPS/TLS

  • Description:

    1. Obtain TLS Certificates: Acquire TLS/SSL certificates for the CouchDB server.
    2. Configure CouchDB TLS: Edit local.ini or default.ini to enable TLS in the [ssl] section, providing paths to certificate and key files.
    3. Enable httpsd Listener: Ensure the httpsd listener is enabled in the [httpd] section.
    4. Redirect HTTP to HTTPS (Recommended): Configure redirection from HTTP to HTTPS, ideally via a reverse proxy.
    5. Verify Configuration: Confirm CouchDB serves requests over HTTPS and validate certificate details.

  • List of Threats Mitigated:

    • Data in Transit Interception (High Severity): Encrypts communication to prevent eavesdropping.
    • Man-in-the-Middle (MITM) Attacks (High Severity): Protects against interception and modification of data in transit.
    • Credential Theft (Medium Severity): Reduces risk of credentials being stolen during transmission.

  • Impact:

    • Data in Transit Interception: High Risk Reduction
    • Man-in-the-Middle (MITM) Attacks: High Risk Reduction
    • Credential Theft: Medium Risk Reduction

  • Currently Implemented:

    • Yes, HTTPS/TLS is enforced in production and staging using CA-signed certificates and HTTP redirection.

  • Missing Implementation:

    • TLS enforcement is inconsistent in development environments. Self-signed certificates should be used at minimum in development.
