CWE-863

Description

Incorrect Authorization (CWE-863) in Kibana can lead to privilege escalation via Input Data Manipulation (CAPEC-153). Elasticsearch cluster privilege declarations originating from integration packages were not validated before being used to mint credentials for enrolled Elastic Agents. A user holding Fleet management privileges could therefore cause every Elastic Agent on a targeted policy to receive a credential carrying arbitrarily elevated Elasticsearch cluster privileges, up to and including full cluster administration.

Affected configurations

• elastic kibana (>= 8.0.0 < 8.19.21) • elastic kibana (>= 9.0.0 < 9.4.6) • elastic kibana (>= 9.5.0 < 9.5.3)
