CVE-2024-49398
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 · uneditedThe affected product is vulnerable to unrestricted file uploads, which may allow an attacker to remotely execute code.
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 vulnerability is an unrestricted file upload issue that allows attackers to upload malicious files (such as webshells) to the affected system, potentially achieving remote code execution. This indicates a lack of proper file type validation, content verification, or secure storage controls in the application's file upload functionality.

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 file upload functionalitySearch your application codebase or configuration for file upload handlers, multipart form handlers, or upload endpoints (e.g., /upload, /file/upload). Also review any HTML forms with enctype='multipart/form-data'.Affected if The system accepts file uploads through any endpoint or feature.
-
Check file type validation configurationLocate the file upload processing code or configuration. Examine whether extension whitelisting and MIME type validation are implemented. Look for checks on file extensions (e.g., .php, .exe, .jsp) and Content-Type headers.Affected if No extension allowlist exists, or only client-side validation is present without server-side enforcement.
-
Inspect upload directory locationFind where uploaded files are stored by examining the upload handler code or web server configuration. Verify if the storage path is within the webroot or accessible via a direct URL.Affected if Uploaded files are stored inside the webroot or in a publicly accessible directory.
-
Verify script execution settingsCheck the web server (Apache, Nginx, IIS) or application server configuration for the upload directory. Look for handler settings that allow executing uploaded files as scripts (e.g., ExecCGI, PHP handler, CGI execution).Affected if Script execution is enabled in the upload directory or uploaded files can be accessed and executed via HTTP requests.
-
Compare installed version to vendor advisoryIf this CVE applies to a specific product version, run 'product_name --version' or check the vendor's version reporting mechanism. Match against any affected version ranges provided in security advisories.Affected if The installed version falls within the affected version range and file upload features are in use.
Your environment is affected if the system accepts file uploads and lacks proper server-side file type validation, stores files in executable locations, or enables script execution in upload directories.
Generated from the published advisory. Verify against your own configuration.
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 (both by extension and magic bytes), store uploads outside the webroot with randomized filenames, disable script execution in upload directories, and apply size limits to prevent executable file uploads.
