CVE-2023-50379
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 · uneditedMalicious code injection in Apache Ambari in prior to 2.7.8. Users are recommended to upgrade to version 2.7.8, which fixes this issue. Impact: A Cluster Operator can manipulate the request by adding a malicious code injection and gain a root over the cluster main host.
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 confidenceApache Ambari versions prior to 2.7.8 contain a code injection vulnerability allowing an authenticated Cluster Operator to manipulate requests and inject malicious code, achieving root privileges on the cluster's main host.

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.
-
Determine if Apache Ambari is installedRun 'ambari-server --version' or check for Ambari processes with 'ps aux | grep ambari'Affected if Ambari is installed and running
-
Check installed Ambari versionExecute 'ambari-server --version' and note the version number returned, or check the Ambari web UI login page footer for the version displayAffected if Version displayed is prior to 2.7.8 (e.g., 2.7.7, 2.7.6, etc.)
-
Verify version against vulnerability rangeCompare your installed version to the affected range: any version lower than 2.7.8 is vulnerableAffected if Installed version is less than 2.7.8
-
Confirm authentication context appliesReview whether Cluster Operator-level users exist in your Ambari deployment by checking user roles in the Ambari web UI under 'Manage Users' or via ambari-server commandsAffected if The code injection only affects deployments where authenticated Cluster Operator users can submit requests to Ambari
You are affected if Apache Ambari is installed with a version lower than 2.7.8 and your deployment accepts authenticated Cluster Operator requests.
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 · scoped2.7.8
Upgrade Apache Ambari to version 2.7.8 or later to resolve the code injection vulnerability.
2.7.8
- Review the Apache Ambari upgrade documentation for upgrading to version 2.7.8
- Take a complete backup of the existing Ambari database and configuration files
- Stop all Ambari services and the Ambari Server
- Upgrade the Ambari Server package to version 2.7.8 using your distribution's package manager
- Upgrade the Ambari Agents on all cluster nodes to version 2.7.8
- Run the Ambari database upgrade script (ambari-server upgrade)
- Start the Ambari Server and verify all services are running correctly
- Validate that the upgrade was successful and the code injection vulnerability is resolved
