Hello all,
I'm conducting a pentest on a IIS/Coldfusion/MSSQL server.
I've found a sql injection flaw, but the server does not allow me to run
"xp_cmdshell" commands.
I use the following trick : exec master.dbo.xp_cmdshell "dir"; --
The server response :
EXECUTE permission denied on object 'xp_cmdshell', database 'master',
owner 'dbo'.
I understand the coldfusion script use a low privileged user. So, two
questions :
- Is there another way to use xp_cmdshell ?
- Is it possible to change the current user ? (like
http://../script?param=1';user(sa,"sa");exec master.dbo.xp_cmdshell
"dir"; --
Thanks in advance for ideas.
FRED
