Vulnerability details
The vulnerability allows an unauthenticated remote attacker to bypass authentication for WeGIA's dependent-document upload handler.
The vulnerability exists due to continued request processing in /WeGIA/html/atendido/docfamiliar_upload.php after unauthenticated users are redirected to the login page. An unauthenticated remote attacker can submit multipart uploads that reach file validation without a session and use valid dependent and document-type identifiers to attempt to attach documents to another person's record.
