CVE-2025-31002
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 Bogdan Bendziukov Squeeze squeeze allows Using Malicious Files.This issue affects Squeeze: from n/a through <= 1.6.
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 confidenceThe Squeeze application has an unrestricted file upload vulnerability allowing attackers to upload dangerous file types (e.g., executable scripts, web shells) without proper validation of file content or type. This could lead to remote code execution if the uploaded malicious file is subsequently accessed and executed by 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 Squeeze application installationSearch for Squeeze application files in the web server document root, common paths include /var/www/html/squeeze, /opt/squeeze, or the application's installation directory. Check for the presence of squeeze.php, squeeze/index.php, or similar application entry points.Affected if The Squeeze application is found installed on the system and the file upload feature is accessible to users.
-
Locate upload functionalityExamine the application source code for file upload forms and handling code. Search for 'enctype=multipart/form-data', 'move_uploaded_file', or '$_FILES' in PHP-based Squeeze installations.Affected if File upload functionality exists and is accessible without authentication or with user-level access.
-
Check file type validation implementationReview the upload handling code for validation logic. Look for whitelist-based checks on file extensions, MIME type verification, and magic byte/header validation of uploaded file content.Affected if No server-side validation exists, or validation relies solely on client-side checks, file extension allowlists are missing, or content type is not verified against actual file headers.
-
Inspect upload storage locationDetermine where uploaded files are stored by reviewing the upload handler code. Check if the upload directory path is within the web server document root or accessible via URL.Affected if Uploaded files are stored within the web root or in a location accessible via HTTP/HTTPS requests, allowing direct access to uploaded content.
-
Verify script execution settingsCheck web server configuration (Apache .htaccess, Nginx config) for the upload directory. Look for directives like 'php_flag engine off', 'RemoveHandler .php', or 'nginx location' blocks that prevent script execution.Affected if Script execution is not disabled in the upload directory, allowing uploaded PHP, ASP, JSP, or other executable files to be run if accessed.
The environment is affected if the Squeeze application is installed with accessible file upload functionality that lacks proper server-side validation, stores files in web-accessible locations, and does not disable script execution in upload directories.

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 whitelist-based file type validation using both magic byte analysis and extension checking, store uploads outside the web root, and disable script execution in upload directories.
