CVE-2022-45855
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 · uneditedSpringEL injection in the metrics source in Apache Ambari version 2.7.0 to 2.7.6 allows a malicious authenticated user to execute arbitrary code remotely. Users are recommended to upgrade to 2.7.7.
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 confidenceSpring Expression Language (SpringEL) injection vulnerability in the metrics source component of Apache Ambari versions 2.7.0 through 2.7.6 allows authenticated users to execute arbitrary code remotely by injecting malicious SpEL expressions.

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 Apache Ambari versionRun 'ambari-server --version' or check the installed package (rpm -q ambari-server or dpkg -l ambari-server)Affected if version is 2.7.0 through 2.7.6 (anything >=2.7.0 and <2.7.7)
-
Identify if metrics source component is configuredReview Ambari configuration files in /etc/ambari-server/conf or /var/lib/ambari-server/resources for metrics-source related settings, or check via Ambari UI under Services > MetricsAffected if metrics source component is enabled and accessible to authenticated users
-
Verify user access to metrics API endpointsCheck Ambari web UI or API access controls for whether authenticated users have permission to access metrics source configurations (typically via /api/v1/clusters/{cluster}/hosts/{host}/metrics)Affected if authenticated users have write or configuration access to the metrics source component
If Apache Ambari version is between 2.7.0 and 2.7.6 AND the metrics source component is enabled and accessible to authenticated users, the environment is affected by this SpringEL injection vulnerability.
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 · scoped2.7.7
Upgrade Apache Ambari to version 2.7.7 or later to remediate this vulnerability.
2.7.7
- 1. Review current Ambari deployment and document existing configurations
- 2. Perform a backup of the Ambari database and configuration files
- 3. Test the upgrade in a non-production/staging environment first
- 4. Stop all Ambari services and agents
- 5. Upgrade Ambari server to version 2.7.7 using the Ambari upgrade process
- 6. Upgrade Ambari agents on all managed nodes to version 2.7.7
- 7. Start Ambari services and verify normal operation
- 8. Validate that the metrics source functionality works correctly post-upgrade
