CVE-2025-67109
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 · uneditedImproper verification of the time certificate in Eclipse Cyclone DDS before v0.10.5 allows attackers to bypass certificate checks and execute commands with System privileges.
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 confidenceEclipse Cyclone DDS before v0.10.5 contains a flaw in certificate time validation where the implementation does not properly verify certificate expiration or validity timestamps. This allows attackers to present expired, revoked, or manipulated certificates that bypass authentication checks, ultimately enabling command execution with System-level privileges.

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 Eclipse Cyclone DDS installationLocate the Cyclone DDS installation directory and check for version information files (such as VERSION, About dialog, or library version strings) or use package manager queries if installed via package managersAffected if The installed version is below 0.10.5
-
Determine if TLS security is enabledReview Cyclone DDS configuration files (typically XML or JSON format in the config directory) for security settings related to TLS, SSL, or certificate-based authenticationAffected if TLS/certificate-based authentication is configured and active in the deployment
-
Inspect certificate configuration settingsExamine the security configuration for any defined certificate paths, certificate verification flags, or trust store settings that govern how certificates are validatedAffected if Certificate validation settings exist in the configuration and are used for peer authentication
A user is affected if Eclipse Cyclone DDS version is below 0.10.5 and TLS/certificate-based authentication is enabled in the Cyclone DDS configuration, as this combination allows the certificate time validation flaw to be exploitable.

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.
dbcve · scoped0.10.5
Upgrade Eclipse Cyclone DDS to version 0.10.5 or later. Additionally, implement certificate chain validation and revocation checking if not already present in the deployment architecture.
v0.10.5
- Identify the current version of Cyclone Data Distribution Service in use
- Download Eclipse Cyclone DDS version 0.10.5 or later from the official Eclipse foundation repository
- Stop all services running instances of Cyclone DDS
- Backup current configuration files and data
- Install the updated Cyclone DDS version 0.10.5
- Restore or update configuration files as needed for the new version
- Restart Cyclone DDS services
- Verify the service is running correctly and certificate validation is functioning
