CVE-2021-20067
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 · uneditedRacom's MIDGE Firmware 4.4.40.105 contains an issue that allows attackers to view sensitive syslog events without authentication.
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 · moderate confidenceRacom MIDGE Firmware version 4.4.40.105 has an authentication bypass vulnerability that allows unauthenticated attackers to access sensitive syslog events. The syslog endpoint or functionality is exposed without requiring any authentication credentials, potentially exposing system events, errors, and operational data.

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.
-
Verify the installed firmware versionAccess the device management interface or use the command line interface to retrieve the current firmware version. Look for a version display in the system information, device status, or about page.Affected if The installed firmware version is exactly 4.4.40.105
-
Identify syslog endpoint accessibilityAttempt to access the syslog viewing functionality or endpoint on the device. This may be accessible via a web path such as /syslog, /log, or similar, or through an API endpoint. Check if the page loads without any login prompt.Affected if The syslog page or endpoint loads and displays log data without requiring any login credentials
-
Confirm authentication requirement for syslogTry accessing the syslog feature through the normal authentication flow (logging in first) and then attempt the same access without logging in. Compare whether both scenarios return the same syslog data.Affected if The syslog data is visible to unauthenticated users who have not provided any credentials
You are affected if your Racom MIDGE device runs firmware version 4.4.40.105 AND the syslog viewing functionality is accessible without requiring any authentication credentials.

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 dataImplement proper authentication and authorization controls on the syslog viewing functionality, or disable the unauthenticated endpoint. Deploy an updated firmware version that addresses this vulnerability.
