CVE-2012-10054 affects Umbraco CMS versions prior to 4.7.1. The vulnerable component is the codeEditorSave.asmx SOAP endpoint, which exposes the SaveDLRScript operation without authentication. This operation permits arbitrary file upload, and a path traversal flaw in the fileName parameter allows an attacker to control the destination path of the uploaded file. By supplying a traversal sequence, an unauthenticated remote attacker can write a malicious ASPX script into the web-accessible /umbraco/ directory and then invoke it over HTTP, resulting in remote code execution on the server.

This repository contains a single Metasploit module (modules/exploits/windows/http/umbraco_upload_aspx.rb) targeting Umbraco CMS 4.7.0.378 running on Windows. The exploit leverages a vulnerability in the SaveDLRScript operation of the codeEditorSave.asmx SOAP web service, which allows unauthenticated attackers to upload arbitrary ASPX files to the /umbraco/ directory via path traversal. The module generates an ASPX web shell containing a Metasploit payload (such as Meterpreter), uploads it to the target, executes it to gain remote code execution, and then attempts to overwrite the file contents for cleanup. The exploit requires the attacker to know the Umbraco login URI and for the IIS application pool user to have write permissions to the Windows Temp folder. The module is operational and provides full remote code execution capabilities. The main network endpoints involved are the /umbraco/webservices/codeEditorSave.asmx SOAP service and the uploaded ASPX file in the /umbraco/ directory.
