| It SEEMS to be exploitable, but there can be lot's of mitigating factors. You must follow traditional sql injection exploiting scenario - get syntax right and then try to pull out some information. And as you have useful visual error feedback, then it should not be very difficult. |

Thanks Waraxe!!
You have reason. It seems to me that it is a classic injection.
Thanks waraxe.
Best Regards. |
