CVE-2018-3827
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 · uneditedA sensitive data disclosure flaw was found in the Elasticsearch repository-azure (formerly elasticsearch-cloud-azure) plugin. When the repository-azure plugin is set to log at TRACE level Azure credentials can be inadvertently logged.
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 · high confidenceThe repository-azure plugin for Elasticsearch has an information disclosure vulnerability where Azure storage credentials are inadvertently logged when the plugin is configured to log at TRACE level. This exposes sensitive authentication material in plaintext log files.

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.
-
Confirm Azure repository plugin is installedRun: bin/elasticsearch-plugin list | grep -i azure, or check the plugins directory for repository-azureAffected if The repository-azure plugin is installed and matches affected versions
-
Check installed plugin versionRun: bin/elasticsearch-plugin info repository-azure, or inspect the plugin-descriptor.properties file in the plugin's directoryAffected if Version is 6.0.0, or between 6.0.1 and 6.2.4 inclusive
-
Verify TRACE logging configurationCheck elasticsearch.yml for: logger.repository-azure.level: TRACE, or check logging.yml for TRACE level assignment to repository-azure categoryAffected if TRACE-level logging is enabled for the repository-azure plugin
-
Inspect log files for exposed credentialsSearch Elasticsearch log files (typically in /var/log/elasticsearch/) for patterns like 'storage_account', 'sas_token', 'key', or 'password' appearing in plain textAffected if Azure credentials appear in plaintext in log files with TRACE logging enabled
User is affected if running a vulnerable version of the repository-azure plugin (6.0.0 or 6.0.1 through 6.2.4) with TRACE-level logging enabled and Azure credentials are present in the logs.

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 dataDisable TRACE-level logging for the repository-azure plugin and rotate any Azure credentials that may have been exposed. Upgrade to a patched version of the plugin when available.
