CVE-2025-23953
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 · uneditedUnrestricted Upload of File with Dangerous Type vulnerability in Scriptonite user files user-files allows Upload a Web Shell to a Web Server.This issue affects user files: from n/a through <= 2.4.2.
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 confidenceScriptonite CMS user-files functionality contains an unrestricted file upload vulnerability allowing attackers to upload malicious web scripts (web shells) to the web server without proper validation of file types or contents. This enables remote code execution and complete server compromise.

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 if Scriptonite is installedLocate the Scriptonite application installation directory and identify the main version file or entry pointAffected if Scriptonite is present in the environment
-
Check Scriptonite versionCompare the installed Scriptonite version against the vendor's release notes or version file to determine if it includes the user-files component vulnerabilityAffected if The installed version is older than the patched version containing the fix for CVE-2025-23953
-
Locate the user-files upload componentSearch for the user-files component directory or module within the Scriptonite installation, typically found under /user-files, /uploads, or similar paths documented in the application structureAffected if The user-files component directory exists and is accessible via the web application
-
Inspect upload endpoint accessibilityAttempt to access the file upload endpoint (commonly /user-files/upload or similar) via HTTP GET to confirm the upload functionality is exposed and accessibleAffected if The upload endpoint returns a valid form or accepts file upload requests without authentication restrictions
-
Verify lack of file type validationTest the upload mechanism by sending a request with a script extension (.php, .jsp, .asp) and check if the server accepts and stores the file without rejecting it based on content-type or magic byte validationAffected if The application accepts and stores executable script files without validating file type or contents
If Scriptonite with the user-files component is running and accepts executable script file uploads without proper validation, the environment is affected by CVE-2025-23953.

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 strict allowlist-based file type validation, store uploads outside web root, rename uploaded files, and disable script execution in upload directories via server configuration.
