CVE-2024-56046
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 VibeThemes WPLMS wplms_plugin allows Upload a Web Shell to a Web Server.This issue affects WPLMS: from n/a through <= 1.9.9.
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 WPLMS WordPress plugin has an unrestricted file upload vulnerability that allows attackers to upload dangerous file types (such as PHP files) directly to the web server. This can result in remote code execution via a web shell, giving attackers full control over the affected system.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 WPLMS plugin versionAccess WordPress admin dashboard, navigate to Plugins > Installed Plugins, locate WPLMS (Vibethemes Wordpress Learning Management System) and read the version number from the plugin details. Alternatively, check the main plugin file header in wp-content/plugins/wplms or similar directory for the 'Version' field.Affected if The displayed version is below 1.9.9.1 (for example, 1.9.9.0, 1.9.8, etc.)
-
Locate file upload functionalityIdentify the upload handler script used by WPLMS. Common paths include wp-content/plugins/wplms/includes/upload.php, wp-content/plugins/wplms/assets/uploads/, or similar directories containing PHP upload handlers. Search for files with 'upload' in the name within the plugin directory.Affected if An upload handler PHP file exists and is accessible via web request without authentication restrictions.
-
Inspect upload validation logicOpen the identified upload handler file and examine the file validation section. Look for code that checks file type, extension, or content before saving the file. Search for functions like wp_check_filetype, mime_content_type, or custom validation logic.Affected if The code lacks validation (no extension whitelist, no MIME type check, no magic byte verification) or contains only client-side checks that can be bypassed.
-
Verify uploaded files are executableCheck the upload directory configuration. Determine where uploaded files are stored (wp-content/uploads/ or plugin-specific directories) and whether .htaccess or server configuration prevents PHP execution in that directory.Affected if Uploaded files are stored within the webroot with .php extension and no server-side protection prevents direct execution via HTTP.
-
Test upload capability (if safe to do so)Using an authorized test account with upload privileges, attempt to upload a benign file with .php extension (for example, a file containing only <?php echo 'test'; ?> ) to the WPLMS upload endpoint and then access the file URL via browser.Affected if The .php file is successfully uploaded and accessible via HTTP, allowing potential remote code execution.
Your environment is affected if WPLMS version is below 1.9.9.1 AND the plugin's upload functionality permits PHP files to be stored in an accessible web directory without proper validation.

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.
dbcve · scoped1.9.9.1
Implement strict file type validation on upload endpoints, including extension allowlist, MIME type verification, and file content inspection. Store uploaded files outside the web root or use .htaccess/nginx directives to prevent execution of uploaded files.
WPLMS version 1.9.9.1 or later
- Backup your WordPress database and files before proceeding
- Log in to your WordPress admin dashboard
- Navigate to Plugins > Installed Plugins
- Find the WPLMS plugin in the list
- Click Update Now on the WPLMS plugin, or go to Plugins > Add New > Upload and install version 1.9.9.1 or later
- Verify the plugin version after update to confirm 1.9.9.1 or newer is installed
- Clear any caching mechanisms if enabled
