- Weakness: CWE-863
Description
Incorrect Authorization (CWE-863) in Kibana Entity Analytics can lead to a loss of security monitoring via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user holding only read-level Security feature access, and no Elasticsearch privileges, could stop the recurring Privilege Monitoring engine task for a Kibana space. Privileged user monitoring then stops producing data for that space while the engine continues to report a healthy state to operators.
Affected products
- Kibana: from 9.1.0 before 9.4.6; from 9.5.0 before 9.5.2 — fixed in 9.4.6, 9.5.2
