CVE-2025-26477
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 · uneditedDell 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 confidenceDell 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed product and versionLocate 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
-
Determine if the management interface is network-accessibleCheck 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
-
Verify low-privileged user account accessReview 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
-
Inspect management interface logs for suspicious activityReview 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.

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.
From vendor data4.0.0.0
Apply 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.
