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 versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.3.0.0, contains an improper neutralization of formula elements in a CSV File vulnerability in the UI. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to remote execution.

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 confidence

This is a CSV injection (formula injection) vulnerability in the Dell ECS and ObjectScale UI. An unauthenticated attacker can embed malicious spreadsheet formulas (=CMD, =EXEC, etc.) into CSV files uploaded through the web interface. When legitimate users open these CSV files in spreadsheet software, the formulas execute arbitrary commands on the victim's machine, enabling remote code execution.

MitigationUpgrade to Dell ECS version 3.8.1.8 or later, or ObjectScale version 4.3.0.0 or later. As a compensating control, implement input validation to strip or neutralize formula characters (=, +, -, @, tab, CR) from CSV uploads before storage and display.

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 or ObjectScale version
    Access the product admin interface and navigate to System Information or About section, or use the CLI command 'ecs-deploy --version' or check the installed RPM/Docker image version
    Affected if Version is 3.8.1.0 through 4.2.x for ECS, or any version below 4.3.0.0 for ObjectScale
  2. Confirm web UI accessibility
    Attempt to reach the ECS or ObjectScale web interface via browser at the configured endpoint (typically https://hostname or the management VIP)
    Affected if Web UI is reachable over the network (the vulnerability exists in the UI component)
  3. Locate CSV export functionality
    In the web UI, navigate to data export, report generation, or download features that produce CSV files
    Affected if CSV export/download feature exists and users can download the resulting files

You are affected if your Dell ECS version is between 3.8.1.0 and 4.2.x inclusive, or your ObjectScale version is below 4.3.0.0, and the web UI with CSV export capability is accessible.

Upgrade available Upgrade to 4.3.0.0 or later
Fixed in 4.3.0.0
Interim mitigation

Upgrade to Dell ECS version 3.8.1.8 or later, or ObjectScale version 4.3.0.0 or later. As a compensating control, implement input validation to strip or neutralize formula characters (=, +, -, @, tab, CR) from CSV uploads before storage and display.

Recommended fix High confidence

Dell ECS or ObjectScale version 4.3.0.0 or later

  1. 1. Identify the current installed version of Dell Elastic Cloud Storage (ECS) or ObjectScale by checking the system administration console or using the management CLI
  2. 2. Confirm the current version is in the affected range: ECS 3.8.1.0 through 3.8.1.7 (or < 4.3.0.0), or ObjectScale < 4.3.0.0
  3. 3. Review the upgrade documentation for Dell ECS or ObjectScale on Dell's support site (www.dell.com)
  4. 4. Schedule a maintenance window for the upgrade procedure
  5. 5. Perform a full backup of all critical data and configuration settings
  6. 6. Download Dell ECS version 4.3.0.0 or later, or ObjectScale version 4.3.0.0 or later from Dell support
  7. 7. Execute the upgrade following Dell's official upgrade procedures
  8. 8. After upgrade, verify the system is running version 4.3.0.0 or later
Caveat Review Dell upgrade documentation for any configuration or compatibility changes between your current version and 4.3.0.0
