Docker Swarm Join Token detected in code

Rule Details

Cortex AppSec Rule ID	APPSEC_SECRET_89
Category	Sensitive Tokens
Severity	MEDIUM
Framework	Git

Impact

A Docker Swarm Join Token is a secret identifier used to authenticate and authorize a new node joining the cluster.

Exposure allows an attacker to join an unauthorized node (manager or worker) to the cluster, potentially leading to cluster configuration breaches and unauthorized execution of workloads.

How to Fix

To remediate exposed Cloud & Infrastructure credentials:

1. Log in to your cloud provider's console.
2. Locate the identity or service account associated with the compromised credentials.
3. Revoke or deactivate the compromised keys immediately.
4. Generate a new set of credentials.
5. Update your environment variables, secrets manager, or pipelines with the new values.

Next, remove the secret from your codebase:

1. Locate the exposed secret in your codebase.
2. Replace the hardcoded value with a secure variable or reference.

Finally, clean your version control history:

1. Permanently remove the sensitive data from your version control history to ensure it cannot be retrieved.

Warning: Revoking infrastructure keys may cause immediate downtime. Ensure you have identified all dependent services before revoking.
