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 version 3.8.1.4 and prior contain an Improper Input Validation vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Code 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

Dell ECS versions 3.8.1.4 and prior contain an improper input validation vulnerability that allows a low-privileged attacker with remote network access to execute arbitrary code. The vulnerability stems from insufficient validation of user-supplied input in the ECS management interface, enabling injection of malicious commands.

MitigationApply the vendor patch for Dell ECS 3.8.1.4 when available. Until then, restrict network access to the ECS management interface to trusted IP addresses only and monitor for suspicious administrative actions.

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 the installed product and version
    Locate the Dell ECS or Dell Objectscale installation and determine the exact version number. In the ECS management interface, navigate to the About or System Information section. For CLI access, use the platform's version command if available.
    Affected if The version is Dell ECS 3.8.1.4 or lower, or Dell Objectscale below 4.0.0.0
  2. Determine if the management interface is network-accessible
    Check network configuration to see if the ECS management interface (typically ports 443, 8443, or similar HTTPS admin ports) is exposed to untrusted networks. Review firewall rules, load balancer configurations, or network ACLs governing the management interface.
    Affected if The management interface is reachable from networks that are not explicitly trusted, especially the internet or untrusted internal segments
  3. Verify low-privileged user account access
    Review user accounts configured in the ECS management system. Identify accounts with limited privileges that still have access to the management interface functionality.
    Affected if Low-privileged accounts exist that can access the management interface where the input validation flaw resides
  4. Inspect management interface logs for suspicious activity
    Review ECS management interface logs, audit logs, or security event logs for unusual or malformed input patterns, unexpected command executions, or indicators of injection attempts.
    Affected if Logs show suspicious command patterns, injection attempts, or unexpected code execution originating from user input fields

You are affected if you are running Dell ECS version 3.8.1.4 or earlier, or Dell Objectscale below version 4.0.0.0, and the management interface is accessible from untrusted network locations.
