Alright i got a script im testing on my local host.
Right now if you do site.com/home.php?start=-2
| Code: | 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 '-2, 18' at line 1
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/content/c/h/a/html/home.php on line 179 |
That comes up.
User table is set out like this
name,pic,ip ,days,points,refs,active,custom,password,verify,fc
Is their anyway i can inject something into on of the user tables columns?Like changing the points for a certain users. Or maybe instead of reading from the user table i can read from the admin table and get the password?
What would be for format? site.com/home.php?start=Select Blah Blah.
Just to display the results if i can't inject.
Here is the Php Code for the home.php?start=
| Code: | <?php
$page_name="home.php";
$start = $_GET['start'];
if(!isset($start)) {
$start = 0;
}
$eu = ($start - 0);
$limit = 18;
$counter = 0;
$columns = 6;
$this1 = $eu + $limit;
$back = $eu - $limit;
$next = $eu + $limit;
$nume = 500;
$query=" SELECT * FROM users ORDER BY days DESC, points DESC LIMIT $eu, $limit ";
$result=mysql_query($query);
echo mysql_error();
while($user = mysql_fetch_array($result))
{
$date = date(Ymd); ?> |

I don't think it will be possible.
You see the only input in that code is $start
The command:
will bring an error if non-number chars are found. The brackets stop $eu variable to be sql injected.
I know if it was written like:
you could do:
| Code: | | site.com/home.php?start="SELECT * FROM blah blah";// |
And here are the problems:
$eu is embedded in the query
I am not sure if you can include spaces, ; sign or the / sign in a URL. I believe the / sign would be recognized differently.
Waraxe might know something else but as far as my knowledge its not possible to sql inject. |
