CVE-2024-55886
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 · uneditedOpenSearch Data Prepper is a component of the OpenSearch project that accepts, filters, transforms, enriches, and routes data at scale. A vulnerability exists in the OpenTelemetry Logs source in Data Prepper starting inversion 2.1.0 and prior to version 2.10.2 where some custom authentication plugins will not perform authentication. This allows unauthorized users to ingest OpenTelemetry Logs data under certain conditions. This vulnerability does not affect the built-in `http_basic` authentication provider in Data Prepper. Pipelines which use the `http_basic` authentication provider continue to require authentication. The vulnerability exists only for custom implementations of Data Prepper’s `GrpcAuthenticationProvider` authentication plugin which implement the `getHttpAuthenticationService()` method instead of `getAuthenticationInterceptor()`. Data Prepper 2.10.2 contains a fix for this issue. For those unable to upgrade, one may use the built-in `http_basic` authentication provider in Data Prepper and/or add an authentication proxy in front of one's Data Prepper instances running the OpenTelemetry Logs source.
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 confidenceOpenSearch Data Prepper's OpenTelemetry Logs source has an authentication bypass vulnerability in versions 2.1.0 through 2.10.1 where custom implementations of the GrpcAuthenticationProvider plugin that use getHttpAuthenticationService() instead of getAuthenticationInterceptor() fail to perform authentication, allowing unauthorized data ingestion.

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 Data Prepper versionLocate the Data Prepper installation and check its version (typically found in a version file, docker image tag, or the Data Prepper logs at startup). Compare the version against the affected range: 2.1.0 through 2.10.1.Affected if The installed version is >= 2.1.0 and < 2.10.2 (or 2.10.1)
-
Confirm OpenTelemetry Logs source is in useExamine the Data Prepper pipeline configuration file (pipelines.yaml) and check whether the otel_logs_source component is defined and enabled.Affected if The OpenTelemetry Logs source (otel_logs_source) is configured in the active pipeline configuration.
-
Identify custom GrpcAuthenticationProvider pluginsReview the Data Prepper plugins directory for custom implementations of the GrpcAuthenticationProvider interface. Check for JAR files or custom code not part of the standard Data Prepper distribution.Affected if Custom GrpcAuthenticationProvider plugin JARs or classes are present in the Data Prepper plugins directory.
-
Inspect custom plugin implementation methodIf custom GrpcAuthenticationProvider plugins exist, decompile or review the source code to determine whether the plugin implements getHttpAuthenticationService() rather than getAuthenticationInterceptor() for authentication.Affected if The custom GrpcAuthenticationProvider implements getHttpAuthenticationService() (instead of getAuthenticationInterceptor()) and this method is invoked by the otel_logs_source.
A user is affected if running Data Prepper 2.1.0-2.10.1 with the OpenTelemetry Logs source enabled and a custom GrpcAuthenticationProvider plugin that relies on getHttpAuthenticationService() instead of getAuthenticationInterceptor().

dbcve · scoped2.10.2
Upgrade to Data Prepper 2.10.2, or alternatively use the built-in http_basic authentication provider, or deploy an authentication proxy in front of Data Prepper instances.
2.10.2
- 1. Identify the current version of OpenSearch Data Prepper by checking the deployed version or configuration.
- 2. Download OpenSearch Data Prepper version 2.10.2 from the official GitHub releases or package repository.
- 3. Stop the running Data Prepper service.
- 4. Replace the existing Data Prepper installation with version 2.10.2.
- 5. Update any pipeline configurations to reference version 2.10.2 if necessary.
- 6. Restart the Data Prepper service.
- 7. Verify that the OpenTelemetry Logs source is now properly enforcing authentication for custom authentication plugins.
