CVE-2023-32189
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsecure handling of ssh keys used to bootstrap clients allows local attackers to potentially gain access to the keys
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSSH keys used for client bootstrap are handled insecurely, allowing local attackers to potentially access these keys through improper storage, permissions, or handling during the bootstrap process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate SSH private keys used for bootstrap or client authenticationSearch for SSH private keys in common bootstrap and configuration directories: ~/.ssh/, /etc/ssh/, /root/.ssh/, and any application-specific bootstrap directories. Use: find / -name 'id_*' -type f 2>/dev/null | head -20Affected if SSH private keys exist in world-readable or group-readable locations with permissive permissions
-
Check file permissions on identified SSH private keysFor each private key found, run: ls -la /path/to/private/key. Verify permissions are 600 (owner read/write only) or stricter (400)Affected if Any SSH private key has permissions wider than 600 (e.g., 644, 664, or 777)
-
Verify SSH key ownership matches the bootstrap service accountCheck owner and group of private keys: stat -c '%U:%G %a' /path/to/key. Confirm owner matches the user or service account that performs bootstrap operationsAffected if SSH keys are owned by unexpected users or shared across multiple accounts
-
Examine bootstrap configuration for embedded or referenced SSH keysReview bootstrap configuration files in /etc/, /opt/, or application config directories for lines containing 'IdentityFile', 'SSH_KEY', or similar directives. Check if keys are hardcoded or referenced insecurelyAffected if Bootstrap configs reference keys from insecure paths or contain inline private key data
-
Search for SSH keys exposed in logs or process environmentsReview system and application logs for patterns matching private key content (-----BEGIN RSA PRIVATE KEY-----). Check running processes: ps auxww | grep ssh for key file paths in process argumentsAffected if Private key content appears in log files or key paths are visible in process listings to other users
Your environment is affected if bootstrap SSH keys exist with permissive file permissions (wider than 600), are owned by non-targeted users, or are exposed through insecure storage, logging, or process visibility.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReview and secure SSH key storage locations, enforce proper file permissions, and ensure keys are handled securely during client bootstrapping to prevent unauthorized local access.
