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 ECS prior to 3.8.0.2 contains an improper verification of cryptographic signature vulnerability. A network attacker with an ability to intercept the request could potentially exploit this vulnerability to modify the body data of the request.

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 ECS prior to version 3.8.0.2 contains an improper verification of cryptographic signature vulnerability. A network attacker positioned to intercept traffic (man-in-the-middle) can modify the body data of requests because the system fails to properly verify cryptographic signatures on the intercepted data.

MitigationUpgrade DELL ECS to version 3.8.0.2 or later which contains the proper cryptographic signature verification fix. Additionally, use TLS/SSL for all communications to protect against network interception.

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 Dell ECS version
    Access the Dell ECS admin interface or use the ECS CLI command to retrieve the installed version number (for example, 'ecs-info' or a similar version query command depending on your deployment). Alternatively, check the system configuration files or about页面 within the ECS management console.
    Affected if The installed version is lower than 3.8.0.2 (for example, 3.7.x, 3.6.x, or earlier).
  2. Verify version via CLI or API
    If available, query the ECS API endpoint or CLI tool for the exact build version. Compare the returned version string against the 3.8.0.2 baseline.
    Affected if The queried version shows a number less than 3.8.0.2.
  3. Confirm the signature verification behavior
    Review the ECS configuration or documentation for the cryptographic signature verification settings on request body data. Check whether the system is configured to verify signatures on incoming request payloads.
    Affected if The system is configured to process request body data without proper cryptographic signature verification (the vulnerable behavior).

You are affected if your Dell ECS installation version is below 3.8.0.2 and the system handles request body data without verifying cryptographic signatures.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

Upgrade available Upgrade to 3.8.0.2 or later
Fixed in 3.8.0.2
Interim mitigation

Upgrade DELL ECS to version 3.8.0.2 or later which contains the proper cryptographic signature verification fix. Additionally, use TLS/SSL for all communications to protect against network interception.

Recommended fix High confidence

3.8.0.2 or later

  1. Identify the current Elastic Cloud Storage version deployed in your environment
  2. Plan and schedule an upgrade window following Dell ECS upgrade procedures
  3. Upgrade Elastic Cloud Storage to version 3.8.0.2 or later
  4. After upgrade, verify the ECS system is operational and all services are running
  5. Validate that the signature verification is functioning correctly by reviewing system logs
