|
||||
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 to upload arbitrary files under the server root.
|
||||
This module abuses the auto deploy feature at the JBoss as_ste.exe's 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 at the backend role in a multiple machines deployment
