CVE-2024-49653
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 james-eggers Portfolleo portfolleo allows Upload a Web Shell to a Web Server.This issue affects Portfolleo: from n/a through <= 1.2.
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 · moderate confidencePortfolleo up to version 1.2 suffers from an unrestricted file upload vulnerability allowing attackers to upload malicious web shell files to the web server. The application lacks proper validation of uploaded file types, enabling remote code execution upon execution of the uploaded payload.

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 Portfolleo installationSearch for Portfolleo files in the web root directory (e.g., find . -name '*portfolleo*' or look for common paths like /portfolleo, /portfolio, or within web server document roots)Affected if Portfolleo software is found on the system
-
Identify Portfolleo versionCheck for a version file or header in the application (common locations: version.php, package.json, or the main index.php header comments). If a changelog or README exists, review it for version information.Affected if The installed version matches any affected version range for CVE-2024-49653 (compare against known vulnerable releases)
-
Locate file upload functionalitySearch for upload-related code or endpoints in the application: look for forms with enctype='multipart/form-data', upload handlers, or API endpoints that accept file uploads. Check routes, controllers, or any PHP/JS files handling 'file', 'upload', or 'POST' requests.Affected if File upload functionality exists and is accessible via the web application
-
Inspect file type validationExamine the upload handler code (typically in upload.php, upload.php, or similar) to determine if file type validation exists. Look for: allowlist of permitted extensions, MIME type checks, Content-Type header validation, or magic byte validation. Also check if uploaded files are stored within the web root.Affected if No proper file type validation (allowlist) is implemented, or dangerous extensions (php, phtml, js, etc.) are accepted, or files are stored in the web-accessible directory
-
Verify upload directory script executionCheck if the upload directory contains an .htaccess file or server configuration that disables script execution (e.g., php_flag engine off or RemoveHandler). Also verify if uploaded files retain their original extensions.Affected if Uploaded files can be executed as scripts (files stored in web root with executable extensions)
A user is affected if Portfolleo is installed with a vulnerable version, the file upload feature is enabled, and proper validation (allowlist-based) or script execution disabling is absent.

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 (MIME type, extension, magic bytes), rename uploaded files to random names, store uploads outside the webroot directory, and disable script execution in the upload directory.
