influxData influxDB before v1.8.10 contains no authentication mechanism or controls, allowing unauthenticated attackers to execute arbitrary commands. NOTE: the CVE ID assignment is disputed because the vendor's documentation states "If InfluxDB is being deployed on a publicly accessible endpoint, we strongly recommend authentication be enabled. Otherwise the data will be publicly available to any unauthenticated user. The default settings do NOT enable authentication and authorization.
The official telegraf docker images before 1.9.4-alpine (Alpine specific) contain a blank password for a root user. System using the telegraf docker container deployed by affected versions of the docker image may allow a remote attacker to achieve root access with a blank password.
InfluxDB before 1.7.6 has an authentication bypass vulnerability in the authenticate function in services/httpd/handler.go because a JWT token may have an empty SharedSecret (aka shared secret).
