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
Dell EMC ScaleIO versions prior to 2.5, contain improper restriction of excessive authentication attempts on the Light installation Agent (LIA). This component is deployed on every server in the ScaleIO cluster and is used for central management of ScaleIO nodes. A remote malicious user, having network access to LIA, could potentially exploit this vulnerability to launch brute force guessing of user names and passwords of user accounts on the LIA.

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

Dell EMC ScaleIO Light Installation Agent (LIA) lacks proper account lockout or rate limiting mechanisms, allowing remote attackers unlimited authentication attempts to brute force user credentials. The LIA runs on every node in the ScaleIO cluster and provides central management functionality, making this a critical exposure.

MitigationUpgrade ScaleIO to version 2.5 or later which addresses the authentication restriction flaw, or implement network-level access controls to limit LIA exposure to trusted networks only.

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. Confirm ScaleIO installation exists in your environment
    Check if Dell EMC ScaleIO software is deployed in your infrastructure. Look for ScaleIO-related processes, services, or documentation.
    Affected if ScaleIO software is present in your environment and the version is below 2.5
  2. Identify ScaleIO version
    Run the ScaleIO command to retrieve the installed version. Common methods include checking the ScaleIO management interface, running 'scli --query_all' or using the ScaleIO GUI to view system information.
    Affected if The installed ScaleIO version is less than 2.5 (for example, 2.0.x, 2.1.x, 2.3.x, etc.)
  3. Verify Light Installation Agent (LIA) is running
    Check if the LIA service or process is active on ScaleIO cluster nodes. The LIA typically runs as a service on each node for central management functionality.
    Affected if LIA is running on any node in the ScaleIO cluster and the ScaleIO version is below 2.5
  4. Check network exposure of LIA
    Identify network accessibility of the LIA service. Determine if the LIA ports are exposed to untrusted networks or the internet, or if they are restricted to internal/trusted network segments.
    Affected if LIA is accessible from networks outside your trusted boundary and the version is below 2.5
  5. Verify account lockout or rate limiting configuration
    Inspect the LIA authentication configuration settings. Check if account lockout policies or rate limiting mechanisms are enabled for LIA authentication attempts.
    Affected if No account lockout policy or rate limiting is configured for LIA authentication, and the ScaleIO version is below 2.5

Your environment is affected if Dell EMC ScaleIO with version below 2.5 is installed, the LIA service is running, and the authentication lacks account lockout or rate limiting protections.

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 2.5 or later
Fixed in 2.5
Interim mitigation

Upgrade ScaleIO to version 2.5 or later which addresses the authentication restriction flaw, or implement network-level access controls to limit LIA exposure to trusted networks only.

Recommended fix High confidence

ScaleIO version 2.5 or later

  1. 1. Review the current ScaleIO cluster deployment and document all nodes running the LIA component.
  2. 2. Plan a maintenance window for the upgrade, ensuring proper backups and cluster state snapshots are available.
  3. 3. Upgrade the ScaleIO cluster to version 2.5 or later, following Dell EMC's standard upgrade procedures.
  4. 4. Verify that all LIA components across all nodes have been successfully updated to the fixed version.
  5. 5. Confirm the authentication restriction is now properly enforced on the LIA service.
Caveat Standard upgrade risks apply - ensure cluster backups exist and follow Dell EMC upgrade documentation for your specific environment
