CVE-2025-26478
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 Certificate Validation vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Information disclosure.
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 certificate validation vulnerability. The flaw allows an unauthenticated attacker with adjacent network access to potentially intercept or manipulate encrypted communications due to insufficient validation of SSL/TLS certificates, leading to information disclosure.

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 installed Dell ECS or Objectscale versionAccess the system management interface or run the product's version command (typically via administrative console or CLI tool provided by Dell). Compare the version number to the affected ranges: ECS <= 3.8.1.4 or Objectscale < 4.0.0.0.Affected if The installed version is 3.8.1.4 or prior for ECS, or any version below 4.0.0.0 for Objectscale.
-
Determine if SSL/TLS is enabled for management interfacesReview the configuration of ECS or Objectscale management interfaces to verify whether HTTPS/SSL/TLS is actively being used for encrypted communications.Affected if SSL/TLS is enabled and in use for management communications.
-
Inspect certificate validation settingsExamine the SSL/TLS configuration for the management interfaces to determine whether certificate validation is properly enforced (check for settings related to certificate verification, trust store configuration, or CA bundle validation).Affected if Certificate validation is disabled, weakly configured, or missing verification of certificate chain, hostname, or revocation status.
-
Assess network exposure of management interfacesIdentify all network-accessible management endpoints and determine whether they are exposed beyond trusted internal networks. Review firewall rules, access control lists, or network segmentation applied to these interfaces.Affected if Management interfaces are reachable from untrusted or adjacent network segments without adequate access restrictions.
A user is affected if they run Dell ECS <= 3.8.1.4 or Objectscale < 4.0.0.0, have SSL/TLS enabled for management, and their management interfaces are accessible from an untrusted adjacent network where a man-in-the-middle attack could occur.

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 when available. Until then, restrict network access to the ECS management interfaces to trusted endpoints only, and monitor for signs of man-in-the-middle activity.
