CVE-2023-25016
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 · uneditedCouchbase Server before 6.6.6, 7.x before 7.0.5, and 7.1.x before 7.1.2 exposes Sensitive Information to an Unauthorized Actor.
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 confidenceCouchbase Server versions prior to 6.6.6, 7.0.x prior to 7.0.5, and 7.1.x prior to 7.1.2 contain an information disclosure vulnerability that allows unauthorized actors to access sensitive information. The specific nature of the exposed data and the attack vector are not detailed in the available documentation.

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.
-
Check Couchbase Server version via CLIRun `couchbase-cli server-info -c localhost` or `cbversion` command in the Couchbase installation directoryAffected if The displayed version is below 6.6.6, or falls between 7.0.0 and 7.0.5, or falls between 7.1.0 and 7.1.2
-
Verify version from installation pathInspect the version file typically located at /opt/couchbase/VERSION.txt or check the Couchbase Web Console login page footer which displays the server versionAffected if The version shown is any of the affected ranges listed in the CVE (prior to 6.6.6, 7.0.5, or 7.1.2)
-
Confirm running Couchbase servicesCheck for running couchbase-server processes using `ps aux | grep couchbase` or by accessing the Couchbase Web Console at the management portAffected if Couchbase Server is running and its version matches the affected ranges
You are affected if any Couchbase Server node is running version 6.6.6以下，或7.0.0至7.0.5之间，或7.1.0至7.1.2之间.
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.
dbcve · scoped6.6.67.0.57.1.2
Upgrade Couchbase Server to version 6.6.6, 7.0.5, 7.1.2 or later. If immediate patching is not feasible, implement network segmentation and authentication controls to limit unauthorized access to the Couchbase Server instance.
Upgrade to 6.6.6, 7.0.5, or 7.1.2 (depending on your current major version line)
- Identify the currently installed Couchbase Server version using 'couchbase-cli server-info' or the web console
- Determine which version branch you are on (6.x, 7.0.x, or 7.1.x)
- Plan maintenance window as upgrade requires cluster downtime
- Backup cluster data using 'cbbackup' or through the web console
- Stop all applications connecting to the Couchbase cluster
- For rolling upgrades if supported, follow Couchbase rolling upgrade procedure; otherwise stop cluster and upgrade all nodes
- Install the appropriate fixed version: 6.6.6 for 6.x users, 7.0.5 for 7.0.x users, or 7.1.2 for 7.1.x users
- After upgrade, verify cluster health using 'couchbase-cli server-list' and check for any errors in logs
