CVE-2025-10116
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 was identified in SiempreCMS up to 1.3.6. This vulnerability affects unknown code of the file /docs/admin/file_upload.php. Such manipulation leads to unrestricted upload. The attack may be launched remotely. The exploit is publicly available and might be used.
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 confidenceAn unrestricted file upload vulnerability exists in SiempreCMS up to version 1.3.6 in the /docs/admin/file_upload.php file. The component lacks proper validation of uploaded files, allowing an authenticated remote attacker to upload arbitrary files (including executable scripts) to the server, potentially achieving code execution.

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.
-
Confirm SiempreCMS installation and versionLocate the CMS installation and identify the version number (check version file, header, or admin dashboard about page). Compare against the affected range: versions 1.3.6 and below.Affected if Installed version is 1.3.6 or lower.
-
Verify vulnerable upload file existsCheck if the file /docs/admin/file_upload.php exists in the web root directory of the SiempreCMS installation.Affected if The file exists and the CMS version is 1.3.6 or lower.
-
Confirm upload endpoint is accessibleAttempt to access the file_upload.php endpoint directly via HTTP request (for example, GET or POST to /docs/admin/file_upload.php) and verify whether authentication is enforced.Affected if The endpoint responds without requiring valid credentials, or accepts uploads from low-privilege authenticated users.
-
Check upload directory script execution settingsIdentify the upload destination directory (check file_upload.php code or upload configuration). Verify whether the web server allows executing script files (PHP, JSP, ASP, etc.) in that directory (check .htaccess, nginx config, or directory permissions).Affected if Script execution is permitted in the upload directory, allowing uploaded files to be executed.
A user is affected if they run SiempreCMS version 1.3.6 or lower, the vulnerable upload file exists, and the upload endpoint is accessible to authenticated attackers or allows script execution in the upload directory.

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 validation (extension, MIME type, and magic bytes), store uploads outside the web root, rename uploaded files, disable script execution in the upload directory, and ensure proper authentication/authorization checks are enforced on the upload endpoint.
