Summary

In Search Guard versions 3.1.1 and earlier, Field Masking (FM) rules are improperly enforced on fields of type IP (IP Address). While the content of these fields is properly redacted in the _source document returned by search operations, the results do return documents (hits) when searching based on specific IP values. This allows to reconstruct the original contents of the field.

Risk Assessment

The risk is the potential disclosure of sensitive data that was supposed to be masked, which could lead to confidentiality breach. Attackers may exploit this to reconstruct original IP field values.

Recommendation

Update Search Guard to a version that includes a fix. If you cannot upgrade immediately, use field level security (FLS) protection on affected fields instead of field masking.
