概要

Advisory title: Field-level security issue with .keyword fields

Affected versions:

OpenSearch 1.0.0-1.3.7 and 2.0.0-2.4.1

Patched versions:

OpenSearch 1.3.8 and 2.5.0

Impact:

There is an issue in the implementation of field-level security (FLS) and field masking where rules written to explicitly exclude fields are not correctly applied for certain queries that rely on their auto-generated .keyword fields.

This issue is only present for authenticated users with read access to the indexes containing the restricted fields.

Workaround:

FLS rules that use explicit exclusions can be written to grant explicit access instead. Policies authored in this way are not subject to this issue.

Patches:

OpenSearch versions 1.3.8 and 2.5.0 contain a fix for this issue.

NVD の説明

OpenSearch is an open source distributed and RESTful search engine. In affected versions there is an issue in the implementation of field-level security (FLS) and field masking where rules written to explicitly exclude fields are not correctly applied for certain queries that rely on their auto-generated .keyword fields. This issue is only present for authenticated users with read access to the indexes containing the restricted fields. This may expose data which may otherwise not be accessible to the user. OpenSearch 1.0.0-1.3.7 and 2.0.0-2.4.1 are affected. Users are advised to upgrade to OpenSearch 1.3.8 or 2.5.0. Users unable to upgrade may write explicit exclusion rules as a workaround. Policies authored in this way are not subject to this issue.
