Hi Marco.
Thank you for your advice.
You are probably talking about BOOLEAN based technique.
Now, we've chosen an approach that will be most optimal from coding aspect.
Also, currently other techniques (error and union) are used far more often
than inference ones (boolean and time-based).
Why is that an optimal approach? Because in boolean technique in
multithreading mode sqlmap is using an generic retrieval of any SQL query
result - 1) retrieve result length 2) distribute among multiple threads.
Now, doing something like lots of 1s and do multithreaded lots of 2s would
screw our internal approach. Believe me, this all has to be VERY generic to
work on all DBMSes for all cases. Implementing your approach would just put
too much effort (rewriting whole sqlmap, not just that enumeration of table
names) with too little positive effects.
Kind regards,
Miroslav Stampar
