Missing Tls in Buffalo with Cockroachdb

A Buffalo application that connects to CockroachDB without Transport Layer Security (TLS) exposes database credentials and query data to interception on the network. CockroachDB supports TLS for client connections, and when TLS is omitted or misconfigured, the channel between the Buffalo server and the database is plaintext. middleBrick scans the associated API endpoints and flags Missing Tls as a high-severity finding under Encryption and Data Exposure, noting that credentials or sensitive records could be exposed in transit.

In a typical Buffalo app, database configuration is central; if the connection string does not enable sslmode=require (or equivalent), the underlying PostgreSQL driver establishes a cleartext TCP connection to the CockroachDB node. An attacker on the same network or path can observe or alter traffic, leading to credential theft or injection. middleBrick cross-references the OpenAPI spec (if provided) with runtime checks, confirming whether authentication mechanisms are transmitted without encryption.

Additionally, without TLS, there is no server identity verification. The application may accept any certificate, enabling man-in-the-middle attacks where an attacker presents a fraudulent certificate to intercept or modify statements. middleBrick flags this as a Missing Tls risk and highlights the need for certificate validation and encrypted channels, aligning findings with OWASP API Top 10 and common compliance frameworks such as PCI-DSS.

To remediate Missing Tls for CockroachDB in a Buffalo application, enforce TLS for every database connection and ensure proper certificate handling. Update the connection parameters to include sslmode=verify-full and provide paths to the CA certificate, client certificate, and client key when required. This ensures encryption and server identity verification.

Example configuration in config.yml for different environments:

production:
  url: postgresql://myuser:[email protected]:26257/mydb?sslmode=verify-full&sslcert=/path/to/client.crt&sslkey=/path/to/client.key&sslrootcert=/path/to/ca.crt

In code, ensure the database handle is created with these settings. Using the pgx driver via Buffalo’s database layer, you can set up a secure connection pool:

import (
  "context"
  "github.com/gobuffalo/buffalo"
  "github.com/jackc/pgx/v5/pgxpool"
)

func app() *buffalo.App {
  // dbURL should come from environment variables in production
  dbURL := "postgresql://myuser:[email protected]:26257/mydb?sslmode=verify-full&sslcert=/certs/client.crt&sslkey=/certs/client.key&sslrootcert=/certs/ca.crt"
  poolConfig, err := pgxpool.ParseConfig(dbURL)
  if err != nil {
    panic(err)
  }
  // Use poolConfig to manage connections securely
  return buffalo.New(buffalo.Options{
    // other app options
  })
}

For local development, you may use sslmode=require to enforce encryption without full verification, but this should never be used in production. In CI/CD workflows, integrate middleBrick’s GitHub Action to fail builds if risk thresholds are exceeded, ensuring TLS enforcement remains part of your pipeline gates.

When deploying to Kubernetes or cloud environments, mount the CA and client certificates as secrets and reference them in the connection string. The CLI tool can be used locally to verify configurations:
