Original description
The description as published by the source.
Improper Input Validation, Authorization Bypass Through User-Controlled Key vulnerability in Apache Camel ElasticSearch Rest Client.
The camel-elasticsearch-rest-client component reads several Exchange headers to control its behaviour - SEARCH_QUERY (an advanced query body), OPERATION (which Elasticsearch operation to run), INDEX_NAME, INDEX_SETTINGS and ID. The string values of these header constants, defined in ElasticSearchRestClientConstant, are plain unprefixed names ('SEARCH_QUERY', 'OPERATION', 'INDEX_NAME', 'INDEX_SETTINGS', 'ID') rather than the 'Camel'-prefixed names used by every other Camel component (for example CamelSqlQuery, CamelMongoDbCriteria, CamelCqlQuery). Camel's inbound HTTP header filter, HttpHeaderFilterStrategy, blocks only header names that begin with 'Camel' or 'camel'. Because the Elasticsearch header names do not carry that prefix, they pass through the inbound filter unchanged. When a Camel route exposes an HTTP entry point (for example platform-http) in front of an elasticsearch-rest-client producer, an untrusted HTTP client can set these headers directly on its request and override the query and operation that the route author configured: reading every document in the index (SEARCH_QUERY with a match_all query), deleting documents (OPERATION set to Delete together with ID), or exfiltrating selected fields. No credentials are required and the producer reads the headers unconditionally.
This issue affects Apache Camel: from 4.3.0 before 4.14.8,…
