CVE-2024-50420
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 aDirectory aDirectory adirectory allows Upload a Web Shell to a Web Server.This issue affects aDirectory: from n/a through <= 1.3.
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 confidenceaDirectory versions up to 1.3 contains an unrestricted file upload vulnerability that allows attackers to upload dangerous file types, specifically web shells, directly to the web server. This enables remote code execution and complete server compromise.

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 aDirectory installationLocate aDirectory by checking for its web application files in the web server directory, or by querying the application for its version information (often visible in login page, admin panel, or version endpoint)Affected if aDirectory is found installed on the system
-
Identify installed versionRetrieve the exact version number from the application (typically in about page, footer, or version API endpoint) and compare it to the affected range: versions 1.3 and below are vulnerableAffected if Installed version is 1.3 or lower
-
Verify file upload feature is enabledLog into the aDirectory admin interface and navigate to settings or modules to confirm if file upload functionality is active, or inspect configuration files for upload-related settingsAffected if File upload feature is enabled and accessible to users
-
Check upload directory placementExamine the web server configuration and upload directory path to determine if uploads are stored within the web root (web-accessible directory)Affected if Upload directory is located inside the web-accessible document root
-
Inspect for existing malicious uploadsSearch upload directories for file types that indicate web shells or malicious scripts (such as .php, .asp, .jsp, .exe files) using file system search toolsAffected if Suspicious executable or script files are found in upload directories
A system is affected if aDirectory version 1.3 or lower is installed with the file upload feature enabled, regardless of upload directory 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 allow-list-based file type validation, perform file content inspection, store uploads outside web-accessible directories, disable script execution in upload directories, and apply any available vendor patches.
