Summary

Apache Syncope has an incorrect authorization vulnerability. Search requests are transformed into SQL, Neo4J or Elasticsearch/Opensearch queries, and the Realms filter that should restrict results to the requester's permissions may be rendered as empty for non-recursive search requests, voiding privilege restrictions.

Risk Assessment

An unauthorized user may access search results outside their permission scope. This can lead to data leakage and breach of Realm isolation.

Recommendation

Upgrade Apache Syncope to version 4.0.8 or 4.1.3. Verify search configuration and user entitlements after the upgrade.

Original NVD description (English source)

Incorrect Authorization vulnerability in Apache Syncope. Any search requests are transformed into SQL, Neo4J or Elasticsearch / Opensearch queries, depending on the actual deployment configuration. An important component of such transformation is the Realms filter, which ensures that the search results are matching the requester's permissions. For non-recursive search requests it is possible that such Realms filter is rendered as empty, thus voiding any restriction on requester privileges. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.7, from 4.1.0-M0 through 4.1.2. Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.
