CVE-2023-25551
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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability exists on a DCE file upload endpoint when tampering with parameters over HTTP. 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 · high confidenceA stored XSS vulnerability exists in the StruxureWare Data Center Expert file upload endpoint. Attackers can inject malicious scripts by tampering with HTTP parameters during file upload operations. The vulnerability allows execution of arbitrary JavaScript in the context of other users' browsers viewing the affected page.

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 installed StruxureWare Data Center Expert versionAccess the web interface and navigate to the About or System Information page, or check the installer/package version on the server. On Windows, check Add/Remove Programs. On Linux, check the RPM/DEB package version.Affected if The installed version is 7.9.2 or any version lower than 7.9.3 (since the fix is in 7.9.3 and later)
-
Confirm the web interface is accessibleVerify that the StruxureWare Data Center Expert web console is running and reachable via HTTP/HTTPS on the configured port (typically 8080 or 443).Affected if The web interface is exposed and accessible to users or attackers
-
Identify if the file upload feature is enabledLog into the web console and locate the file upload functionality. This is typically found in settings, firmware upload, backup/restore, or device configuration sections.Affected if The file upload feature is available and enabled in the web interface
-
Review web server access logs for upload endpoint requestsExamine the HTTP access logs (typically found in the application logs directory) for POST requests to the file upload endpoint. Look for unusual or tampered HTTP parameters.Affected if The server logs show requests to the upload endpoint with suspicious parameter values containing script tags or encoded JavaScript
You are affected if the installed version is 7.9.2 or earlier AND the web-based file upload feature is accessible and enabled in your environment.

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 dataImplement proper input validation and output encoding on the file upload endpoint parameters. Upgrade to version 7.9.3 or later if available, or apply vendor-supplied patches.
