CVE-2024-4306
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 · uneditedCritical unrestricted file upload vulnerability in HubBank affecting version 1.0.2. This vulnerability allows a registered user to upload malicious PHP files via upload document fields, resulting in webshell execution.
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 confidenceHubBank version 1.0.2 contains an unrestricted file upload vulnerability in document upload fields. Registered users can upload arbitrary PHP files which are stored in a web-accessible location, allowing remote code execution via webshell. The application fails to validate file types, extensions, or content before storing uploaded files.

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 Hubbank versionLocate the version information for your Hubbank installation (check application metadata, about page, or configuration files) and verify it is exactly version 1.0.2Affected if Your installed version is 1.0.2 of Hubbank
-
Locate document upload functionalityIdentify all file upload endpoints in the application, typically found in document management, profile, or attachment sections. Check the HTML forms and API endpoints for input type='file' elementsAffected if The application contains document upload fields accessible to registered users
-
Determine upload storage locationUpload a harmless test file (such as a text file) and examine the response to determine where files are stored. Check if the resulting URL is within the web root (public_html, www, or similar)Affected if Uploaded files are stored in web-accessible directories
-
Test for unrestricted file type handlingAttempt to upload a file with a .php extension containing simple PHP code (e.g., <?php phpinfo(); ?>) to the document upload featureAffected if The application accepts and stores .php files without rejection or sanitization
-
Verify uploaded PHP files are executableAccess the uploaded .php file via its web URL in a browser and observe if the PHP code executes rather than being downloadedAffected if Uploaded .php files are accessible via HTTP and execute rather than being served as plain text or blocked
You are affected if you are running Hubbank version 1.0.2 and the document upload feature stores files in web-accessible locations without validating file types, allowing PHP webshell uploads.

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, and magic bytes), store uploads outside the webroot or in non-executable locations, rename files upon upload, and disable script execution in upload directories.
