CVE-2025-29394
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 · uneditedAn insecure permissions vulnerability in verydows v2.0 allows a remote attacker to execute arbitrary code by uploading a file type.
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 confidenceThis is an insecure file upload vulnerability in verydows v2.0 where insufficient permission controls on the upload mechanism allow a remote attacker to bypass file type restrictions and upload malicious executable files (such as PHP scripts), leading to arbitrary code execution on the 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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed verydows versionLocate the version file or footer in the application installation directory, or check the admin dashboard for version informationAffected if The installed version is verydows v2.0 specifically, as this version contains the vulnerable upload mechanism
-
Locate the file upload functionalitySearch the application source code for upload-related scripts, forms, or endpoints - look for file input handlers and POST request handlers that process file uploadsAffected if The upload functionality exists and is accessible to remote users without additional authentication barriers
-
Examine the upload directory configurationCheck the application configuration files and source code to identify where uploaded files are stored relative to the web rootAffected if Uploaded files are stored within the web-accessible directory (htdocs, public_html, or similar) allowing direct URL access to uploaded content
-
Verify file type validation controlsReview the upload handling code to determine if file type restrictions exist and whether they can be bypassed - check if validation relies solely on client-side checks or easily manipulated parameters like Content-Type headers or file extensionsAffected if The application only performs client-side validation, checks only file extensions, or relies on user-controllable parameters without server-side magic byte verification
-
Confirm script execution is allowed in upload directoryCheck if the upload directory lacks restrictions on executing uploaded files - look for absence of .htaccess rules, disabled script handlers, or non-executable file system permissionsAffected if The upload directory permits execution of uploaded files, particularly PHP, ASP, or other server-side scripts
A user is affected if they are running verydows v2.0 with its file upload feature enabled and the upload directory is web-accessible with script execution permissions.

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, verify file MIME types and magic bytes server-side, store uploaded files outside the web root or disable script execution in the upload directory, and rename uploaded files to prevent direct access.
