CVE-2024-23451: Elasticsearch Incorrect Authorization vulnerability

Incorrect Authorization issue exists in the API key based security model for Remote Cluster Security, which is currently in Beta, in Elasticsearch 8.10.0 and before 8.13.0. This allows a malicious user with a valid API key for a remote cluster configured to use the new Remote Cluster Security to read arbitrary documents from any index on the remote cluster, and only if they use the Elasticsearch custom transport protocol to issue requests with the target index ID, the shard ID and the document ID. None of Elasticsearch REST API endpoints are affected by this issue.

Root Cause Analysis

The provided vulnerability information describes an authorization flaw in Elasticsearch's Remote Cluster Security API key handling when using the custom transport protocol. However, the advisory does not provide specific code references, commit diffs, or implementation details that would allow precise identification of vulnerable functions. The vulnerability stems from improper authorization checks during transport protocol requests involving index ID, shard ID, and document ID parameters, but without access to Elasticsearch's internal security implementation details or patch information, we cannot confidently map this to specific function names or file paths. The REST API is explicitly stated to be unaffected, narrowing the scope to internal transport protocol handling code, but insufficient public technical details prevent high-confidence function identification.
