CVE-2013-3633
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 SCALANCE X-200 switch family (incl. SIPLUS NET variants) (Versions < V5.0.0 for CVE-2013-3633 and versions < V4.5.0 for CVE-2013-3634), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.1.0). The user privileges for the web interface are only enforced on client side and not properly verified on server side. Therefore, an attacker is able to execute privileged commands using an unprivileged account.
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 confidenceThe SCALANCE X-200 and X-200IRT switch web interfaces perform privilege checks only in client-side code (JavaScript) without validating user authorization on the server. This allows an authenticated unprivileged user to bypass authorization and execute privileged/administrative commands by directly calling server-side endpoints that lack proper server-side authorization checks.

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 the SCALANCE device modelAccess the device web interface or console and retrieve the model name from the system information or status page. Common paths: /sysinfo or through the main status dashboard showing model number like X200irt, X204irt, etc.Affected if The model is X200irt, X200 4p Irt, X201 3p Irt, X202 2irt, X202 2p Irt, X204irt, or Xf204irt.
-
Check the installed firmware versionNavigate to the device web interface System > Firmware or System > Info page to view the firmware version. Alternatively, access via console and use the 'show version' or 'info' command.Affected if The firmware version is 5.0.0 or lower for X200irt models, or any version for X200 4p Irt, X201 3p Irt, X202 2irt, X202 2p Irt, X204irt, and Xf204irt models.
-
Confirm the web interface is enabledCheck the device configuration under Network Settings > HTTP/HTTPS or System > Services to see if the web interface (HTTP/HTTPS) is currently enabled.Affected if The web interface HTTP or HTTPS service is enabled and accessible.
-
Verify client-side only authorization behaviorLog into the web interface with a non-administrative user account. Observe that administrative functions are hidden or disabled in the JavaScript. Then, use a web proxy or browser developer tools to directly request a known administrative endpoint (such as /config or /admin) without proper admin privileges to see if the server accepts the request.Affected if Administrative functions are accessible via direct server requests without proper server-side authorization validation.
If the device is an affected SCALANCE model, the web interface is enabled, and the firmware version falls within the affected ranges, the vulnerability is present.

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 dataUpdate firmware to V5.0.0 or later for SCALANCE X-200 or V5.1.0 or later for X-200IRT. If updates are unavailable, disable the web interface and use SNMP or console management with strict access controls.
