CVE-2022-36640
Published: 02 September 2022
Summary
CVE-2022-36640 is a critical-severity Incorrect Default Permissions (CWE-276) vulnerability in Influxdata Influxdb. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 8.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
InfluxData InfluxDB versions before 1.8.10 lack any built-in authentication mechanism or access controls by default, as noted in CVE-2022-36640. This configuration weakness, assigned CWE-276, permits unauthenticated network access to the database instance and was given a CVSS 3.1 score of 9.8. The assignment itself is disputed by the vendor, whose documentation explicitly states that authentication is disabled out of the box and must be enabled manually when the service is reachable from untrusted networks.
An unauthenticated attacker with network connectivity can therefore issue arbitrary commands against the database, resulting in complete loss of confidentiality, integrity, and availability of the stored time-series data and the underlying system.
Vendor references direct users to upgrade to InfluxDB 1.8.10 or later via the published packages and to enable authentication and authorization settings before exposing any endpoint publicly, consistent with the guidance that unauthenticated deployments leave all data available to any remote user.
The associated EPSS score has remained low, with a current value of 0.0679 and a peak of 0.0816.

Vulnerability details
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Access control policy can specify and enforce secure default permissions for resources.
Guides setting of default permissions to the minimum required level.
Establishes requirements for appropriate default permissions on system resources as part of configuration management.
Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.
Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.
Requires documented processes that include setting and maintaining correct default permissions for configuration items.
Requires addressing secure default permissions in physical and environmental protection controls.
Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
