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 RTI Connext Professional versionCheck the product installation directory or run the version command provided with the installation (such as 'rtiddsgen -version' or check the README/VERSION file in the installation root)Affected if The installed version is 7.5.0 or any version between 7.5.0 and 7.6.0 (exclusive)
-
Confirm Security Plugins are in useExamine your DDS domain configuration XML files (usually *.xml) for the presence of security-related plugin elements such as <security> or <plugin> tags referencing security functionality, or check if security is enabled via environment variables or startup scriptsAffected if Security plugins are enabled or configured in the Connext deployment
-
Check for file-based security configurationsInspect your domain configuration for any file-based security settings, particularly those that may involve file paths or file access permissions within the security plugin configurationAffected if File-based security configurations are present and the version is in the affected range
-
Review application logs for security component activityEnable debug logging for the security components and examine log output for any mentions of security plugins loading or file operations within the security subsystemAffected if Security plugin components are being loaded and the version falls within 7.5.0 to 7.6.0
You are affected if RTI Connext Professional is installed with a version >= 7.5.0 and < 7.6.0 and the security plugins are enabled or configured in your environment.
