CVE-2025-30034
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 · uneditedA vulnerability has been identified in SIMATIC RTLS Locating Manager (All versions < V3.3). Affected devices do not properly validate input sent to its listening port on the local loopback interface. This could allow an unauthenticated local attacker to cause 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 confidenceSIMATIC RTLS Locating Manager versions prior to V3.3 fail to validate input received on its listening port bound to the local loopback interface. An unauthenticated attacker with local access can send specially crafted packets to this port, causing the service to crash or become unresponsive, resulting in a denial of service condition.

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 SIMATIC RTLS Locating Manager installationCheck for the presence of SIMATIC RTLS Locating Manager software on the system using system inventory tools, program files directory, or Siemens software listingsAffected if The software is installed on the system
-
Determine installed version of SIMATIC RTLS Locating ManagerLocate the version information through the software's about dialog, installed programs list, or version file in the installation directoryAffected if The version is lower than 3.3 (e.g., 3.2.x, 3.1.x, etc.)
-
Confirm the service is runningCheck if the SIMATIC RTLS Locating Manager service or process is currently active using task manager, service console, or process enumeration toolsAffected if The service is running and accepting connections
-
Verify loopback interface bindingInspect network configuration to confirm the service is listening on the local loopback interface (127.0.0.1) using netstat or similar network diagnosticsAffected if The service is bound to loopback and accessible locally
A system is affected if SIMATIC RTLS Locating Manager version lower than 3.3 is installed and the service is running with loopback interface accessibility.

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 · scoped3.3
Update SIMATIC RTLS Locating Manager to version V3.3 or later. If immediate patching is not feasible, consider network segmentation controls to limit local access to the affected system and monitor loopback traffic for anomalous patterns.
V3.3
- Obtain SIMATIC RTLS Locating Manager V3.3 or later from the official Siemens cert-portal or support website
- Stop the SIMATIC RTLS Locating Manager service
- Install version 3.3 or later following Siemens installation documentation
- Restart the SIMATIC RTLS Locating Manager service
