• → Detect unauthenticated GET/POST requests to the file management endpoint path containing '?id=/Uploads' — no session/auth cookie required by the application. ↗
• → Alert on HTTP POST requests uploading files with .aspx extensions to the /Uploads/Documents/ directory path. ↗
• → Monitor for HTTP GET requests to /Uploads/Documents/*.aspx following a POST to FileExplorer/Explorer.aspx, indicating webshell execution after upload. ↗

• · The vulnerable endpoint is only present in KBVault MySQL version 0.16a; confirm the target application version before applying detections. ↗
• · The vulnerability is Windows-platform specific (IIS/ASPX execution environment); detections for webshell upload are only relevant on Windows-hosted deployments. ↗
