CWE-770

Description

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). A query expression accepted by a connector reporting operation was processed without any limit on its size, and an oversized expression caused the Kibana process to spend an unbounded amount of time evaluating it. An authenticated user with read-only privileges was able to send a single request that left Kibana unable to serve any user until the process was restarted.

Affected configurations

• elastic kibana (>= 8.0.0 < 8.19.20) • elastic kibana (>= 9.0.0 < 9.4.5)
