I known the real reason
[Macromedia][SQLServer JDBC Driver][SQLServer]Conversion failed when converting the varchar value ' IP Address. . . . . . . . .' to data type int.
Maybe error in coldfusion can display only 32 charactor...
Any body can help me see more character... |

xp_cmdshell should work fine, so I guess, that data in table k1 is in full form and you have problem getting data back from k1?
How can you fetch data from k1? Via UNION SELECT? Tried using substrings?
And by the way, better option is to upload Netcat to the database server and execute it for reverse shell. But before that you can do ping in order to confirm, that database server can communicate with your computer.
One more thing I spotted ... table k1 ... you declared it as:
create table k1 (id int identity,nn varchar(max))
Try using direct value:
create table k1 (id int identity,nn varchar(4000))
And by the way, what version of MS SQL it is? 2005? 2000? |
