|
||||
This module exploits a vulnerability found in SharePoint Server 2007 SP2. The
|
||||
software contains a directory traversal, that allows a remote attacker to write
|
||||
arbitrary files to the filesystem, sending a specially crafted SOAP ConvertFile
|
||||
request to the Office Document Conversions Launcher Service, which results in code
|
||||
execution under the context of 'SYSTEM'.
|
||||
|
||||
The module uses uses the Windows Management Instrumentation service to execute an
|
||||
arbitrary payload on vulnerable installations of SharePoint on Windows 2003 Servers.
|
||||
It has been successfully tested on Office SharePoint Server 2007 SP2 over Windows
|
||||
2003 SP2.
