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 · unedited
The web server on Siemens SCALANCE X-200IRT switches with firmware before 5.2.0 allows remote attackers to hijack sessions via unspecified vectors.

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 confidence

The SCALANCE X-200IRT switch web server prior to firmware 5.2.0 contains a session hijacking vulnerability that allows remote attackers to intercept and take over valid user sessions through unspecified vectors. This affects the web-based management interface used for configuring industrial network switches.

MitigationUpgrade SCALANCE X-200IRT firmware to version 5.2.0 or later to resolve the session hijacking vulnerability in the web server.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device via its web interface or CLI and confirm the exact model number is SCALANCE X-200IRT or related X-200 series variant
    Affected if The device model is a Siemens SCALANCE X-200IRT switch
  2. Check the installed firmware version
    Locate the firmware version information in the device's web-based management interface (typically under System > Firmware or similar status page) or via CLI command
    Affected if The firmware version is 5.1.1 or lower (any version <= 5.1.1)
  3. Verify if web-based management is enabled
    Check the device configuration settings for web server or HTTP/HTTPS management access. This is typically found under Interface Settings or Network Configuration in the web UI
    Affected if Web-based management interface is enabled and accessible on the network

You are affected if the device is a SCALANCE X-200IRT with firmware version 5.1.1 or lower and the web-based management interface is enabled
