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 · unedited
The official spiped docker images before 1.5-alpine contain a blank password for a root user. Systems using the spiped docker container deployed by affected versions of the docker image may allow an remote attacker to achieve root access with a blank password.

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 · high confidence

The spiped Docker image prior to version 1.5-alpine contains a root user account configured with a blank/empty password. This configuration allows remote attackers who can reach the container to authenticate as root without any credentials, granting full system control.

MitigationUpdate the spiped docker image to version 1.5-alpine or later, which addresses the blank root password. Ensure the container is not exposed to untrusted networks until the update is applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if you are using the spiped Docker image
    Run 'docker images' or check your docker-compose.yml/kubernetes manifests for references to 'spiped' or 'spiped-alpine' image
    Affected if The spiped Alpine Docker image is present in your environment
  2. Check the installed version of the spiped image
    Run 'docker images | grep spiped' to see the image tag/version, or 'docker inspect <container-id>' to check the image reference
    Affected if The image version is tagged as anything below 1.5 (such as latest, or a version number less than 1.5), or if no version tag is specified (defaults to latest which may be old)
  3. Determine if the container is exposed to network access
    Review your container networking configuration: run 'docker inspect <container-id>' and check HostConfig.PortBindings, or review your firewall/network policy rules to see if the container ports are accessible from untrusted networks
    Affected if The spiped container ports (typically 8080 or as configured) are accessible from outside your trusted network or directly from the internet

You are affected if you are running a spiped Alpine Docker image version below 1.5 that is accessible over the network, as this combination enables unauthenticated root access.

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.

dbcve · scoped
Upgrade available Upgrade to 1.5 or later
Fixed in 1.5
Interim mitigation

Update the spiped docker image to version 1.5-alpine or later, which addresses the blank root password. Ensure the container is not exposed to untrusted networks until the update is applied.

Recommended fix High confidence

1.5-alpine (or later)

  1. Pull the fixed spiped Alpine Docker image version 1.5-alpine or later: docker pull spiped:1.5-alpine
  2. Update your deployment configuration to reference the new image version (1.5-alpine or later)
  3. Redeploy the spiped container using the updated image
  4. Verify the root user no longer has a blank password by attempting to SSH or access the container with root and an empty password - it should fail
