CVE-2023-25550
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 CWE-94: Improper Control of Generation of Code ('Code Injection') vulnerability exists that allows remote code execution via the “hostname” parameter when maliciously crafted hostname syntax is entered. Affected products: StruxureWare Data Center Expert (V7.9.2 and prior)
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 confidenceA code injection vulnerability (CWE-94) exists in StruxureWare Data Center Expert v7.9.2 and prior. The vulnerability allows remote code execution via the 'hostname' parameter when maliciously crafted hostname syntax is entered, indicating insufficient input validation/sanitization on the hostname field.

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 installed StruxureWare Data Center Expert versionAccess the web interface and navigate to the About/Help section, or check the software installation directory for version information files. If CLI access is available, use the system's package manager or application version command.Affected if The installed version is 7.9.2 or any prior version (anything <= 7.9.2).
-
Locate the hostname configuration interfaceLog into the StruxureWare Data Center Expert web console and locate the network settings or device configuration section where hostname parameters can be modified.Affected if The web interface is accessible and the hostname input field is present without proper input validation controls.
-
Determine input validation status on hostname fieldAttempt to inject special characters or shell syntax characters (such as semicolons, pipes, backticks, or $() command substitution) into the hostname parameter to observe if the application sanitizes or rejects these inputs.Affected if The application accepts and processes malicious hostname syntax without sanitization, allowing code injection characters to pass through.
A system is affected if StruxureWare Data Center Expert version is 7.9.2 or prior AND the hostname parameter in the web interface accepts unsanitized input containing code injection characters.

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 · scopedUpgrade to a patched version of StruxureWare Data Center Expert. If no patch is available, implement strict input validation on the hostname parameter to reject special characters and syntax that could be interpreted as code.
