CVE-2020-10641
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn unprotected logging route may allow an attacker to write endless log statements into the database without space limits or authentication. This results in consuming the entire available hard-disk space on the Ignition 8 Gateway (versions prior to 8.0.10), causing a denial-of-service condition.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn unprotected logging endpoint in Ignition 8 Gateway (versions prior to 8.0.10) lacks authentication and rate limiting, allowing unauthenticated attackers to submit arbitrary log entries directly to the database without constraints. This causes unbounded disk consumption leading to complete denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Ignition Gateway versionNavigate to the Gateway's main status page or check the installation directory for version info. The version is typically displayed on the Gateway startup page or can be retrieved via the Gateway status endpoint.Affected if Installed version is 8.0.x where x is less than 10 (e.g., 8.0.0 through 8.0.9)
-
Verify the logging endpoint is exposedInspect the Gateway's web configuration and confirm the logging endpoint (typically at /data/logs or similar internal logging routes) is accessible without authentication.Affected if The logging endpoint responds without requiring credentials
-
Check for rate limiting configurationReview the Gateway's security settings for the logging subsystem and verify whether rate limiting or request throttling is enabled on log submission endpoints.Affected if Rate limiting is disabled or not configured on the logging endpoint
-
Search for unauthorized log entriesQuery the internal logging database or log files for entries with unusual timestamps, suspicious content patterns, or entries originating from unauthenticated sources that do not match expected logging behavior.Affected if Log database contains unexpected entries with anomalous timestamps or content suggesting external injection
-
Monitor disk usage for log directoriesCheck the disk space consumption of the logging data directories, particularly the folder where the Gateway stores submitted log entries.Affected if Log directory shows abnormally high or rapidly growing disk usage beyond normal application logging volumes
The environment is affected if Ignition Gateway version 8.0.x (where x < 10) is running and the unprotected logging endpoint accepts unauthenticated requests, leading to excessive log storage.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data8.0.10
Upgrade Ignition Gateway to version 8.0.10 or later, which implements proper authentication and rate limiting on the logging route.
