CVE-2018-3828
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 · uneditedElastic Cloud Enterprise (ECE) versions prior to 1.1.4 contain an information exposure vulnerability. It was discovered that certain exception conditions would result in encryption keys, passwords, and other security sensitive headers being leaked to the allocator logs. An attacker with access to the logging cluster may obtain leaked credentials and perform authenticated actions using these credentials.
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 confidenceElastic Cloud Enterprise versions before 1.1.4 contain an information exposure vulnerability where exception conditions leak encryption keys, passwords, and security-sensitive headers to allocator logs. An attacker with access to the logging infrastructure can obtain these exposed credentials and perform authenticated actions.

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 Elastic Cloud Enterprise versionRun command: docker images | grep -i elastic-cloud-enterprise or check /opt/elastic/cloud/ece-installation/.installed version file if available. Alternatively, query the ECE API endpoint: GET /api/v1/platform/cluster/statsAffected if Installed version is any version before 1.1.4 (e.g., 1.1.0, 1.1.1, 1.1.2, 1.1.3)
-
Verify allocator logging is enabledCheck ECE configuration files in /opt/elastic/cloud/ece-installation/ for allocator logging settings. Look for logging-related configuration in ece-config.yml or allocator configurationAffected if Allocator logging is enabled and logs are written to disk or a logging infrastructure that could be accessed by an attacker
-
Examine allocator log files for sensitive data exposureLocate allocator logs typically stored in /var/log/elastic/allocator/ or within the Docker container logs directory. Search for patterns like 'password', 'key', 'Authorization', 'X-Elastic-Api-Key' in exception/error logsAffected if Logs contain plaintext passwords, encryption keys, or security-sensitive headers in exception stack traces or error messages
-
Review log access controlsAudit file system permissions on log directories and review who has access to the logging infrastructure (e.g., log aggregation systems like Elasticsearch, Splunk, or syslog)Affected if Log files or log aggregation systems are accessible to unauthorized users or processes beyond the intended administration team
Environment is affected if Elastic Cloud Enterprise version is below 1.1.4 AND allocator logs are being generated, as exception conditions in those logs may contain exposed credentials.
Generated from the published advisory. Verify against your own configuration.
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 data1.1.4
Upgrade ECE to version 1.1.4 or later to patch the vulnerability. Additionally, audit log access controls and review existing logs for any leaked credentials that may have been captured.
