Description
This module can be used to execute a payload on Umbraco CMS 4.7.0.378.
The payload is uploaded as an ASPX script by sending a specially crafted
SOAP request to codeEditorSave.asmx, which permits unauthorized file upload
via the SaveDLRScript operation. SaveDLRScript is also subject to a path
traversal vulnerability, allowing code to be placed into the web-accessible
/umbraco/ directory.
The module writes, executes and then overwrites an ASPX script; note that
though the script content is removed, the file remains on the target. Automatic
cleanup of the file is intended if a meterpreter payload is used.
This module has been tested successfully on Umbraco CMS 4.7.0.378 on a Windows
7 32-bit SP1. In this scenario, the "IIS APPPOOL\ASP.NET v4.0" user must have
write permissions on the Windows Temp folder.
