Improper Validation of Array Index (CWE-129) exists in Metricbeat can allow an attacker to cause a Denial of Service through Input Data Manipulation (CAPEC-153) via specially crafted, malformed payloads sent to the Graphite server metricset or Zookeeper server metricset. Additionally, Improper Input Validation (CWE-20) exists in the Prometheus helper module that can allow an attacker to cause a Denial of Service through Input Data Manipulation (CAPEC-153) via specially crafted, malformed metric data.
AnalysisAI
Denial of Service in Prometheus and Kibana metricsets can be triggered by sending specially crafted malformed payloads to Graphite, Zookeeper, or Prometheus data sources due to improper array index validation and input validation flaws. An unauthenticated attacker on the network can exploit this to crash monitoring services without user interaction. No patch is currently available.
Technical ContextAI
Classified as CWE-129 (Improper Validation of Array Index). Affects the Prometheus helper component of Kibana.
