CVE-2021-32504
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 · uneditedUnauthenticated users can access sensitive web URLs through GET request, which should be restricted to maintenance users only. A malicious attacker could use this sensitive information’s to launch further attacks on the system.
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 confidenceThis is an authentication bypass vulnerability where unauthenticated users can access sensitive web URLs intended only for maintenance users via GET requests. The issue allows unauthorized access to maintenance-related endpoints that should require proper authentication, potentially exposing sensitive system information.

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.
-
Identify Sick Ftmg device in your environmentLocate any SICK FTMG hardware or software installations in your network inventory or physically in your facilityAffected if The device/product is a Sick Ftmg system
-
Determine the installed firmware versionAccess the device management interface or system settings to view the current firmware version; consult product documentation for version lookup commands if neededAffected if The firmware version is less than 2.8 (e.g., 2.7, 2.6, earlier versions)
-
Identify maintenance-related web endpointsReview the application's URL structure or API documentation to locate maintenance-related paths (commonly /maintenance, /admin, /debug, or similar administrative endpoints)Affected if The product exposes web-based maintenance or administrative endpoints
-
Test unauthenticated access to maintenance URLsSend a GET request to suspected maintenance endpoints without providing any authentication credentials or session tokensAffected if The request returns a successful response (HTTP 200) instead of requiring authentication (e.g., redirect to login, HTTP 401/403)
You are affected if you have a Sick Ftmg device running firmware version less than 2.8 and maintenance web URLs are accessible without any authentication.

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.
dbcve · scoped2.8
Implement proper access control checks on all maintenance URLs to ensure only authenticated and authorized maintenance users can access sensitive endpoints. All sensitive web URLs should require authentication and role-based authorization before granting access.
Firmware version 2.8 or later
- Identify all SICK Ftmg devices on the network running firmware versions prior to 2.8
- Access the device management interface and verify the current firmware version
- Obtain the official firmware version 2.8 or later from SICK's official support portal (sick.com)
- Follow SICK's documented firmware upgrade procedure to apply version 2.8 or later
- After upgrading, verify the device is functioning correctly
- Confirm that unauthenticated users can no longer access sensitive web URLs that should require maintenance user authentication
