I am trying to make an SQL injection ...
in the input field i type: '
and i got ...
| Code: | Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /var/www/****.com/html/l***.php on line 6**
INSERT INTO Search_terms VALUES (NULL,'''',,'11.111.11.111',now())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 ''11.111.11.111',now())' at line 1
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /var/www/****.com/html/l***.php on line 7** |
is the injection possible in this scenario ? what should i do ?

you didnt make any tests if the application has an sql injection.
good test to make are..
http://localhost/index.php?pageid=1+and+1=1 ( TRUE )
http://localhost/index.php?pageid=1+and+1=2 ( FALSE )
if those tests are correct then the web application suffers from sql injection
Then based on many factors like mysql version etc etc
you proceed with other tests if its blind or normal sql injection
I would recommend :
0x90 absinthe sql injector
paros proxy
and priamos sql injector
and Acunetix web vulnerability scanner
BE CAREFULL .. Those apps make a lot of traffic and your ip will be logged easily !!!!! |

do what he said. and 1=0 = False Output and 1=1 = True Output.
If this works then you have a sql injection. |

You seem to have sql-related coding bug in INSERT query,so if it's sql injection, then probably you need blind injection exploitation.
But specific sql error message is rather confusing:
| Code: |
VALUES (NULL,'''',,'11.111.11.111',now())
|
It seems, that single quote is sanitized by making it double (''), but one field in INSERT query is empty (,,). So I'm not sure, that this coding bug is exploitable. Are you sure, that you copy-pasted sql error exactly how it was originally?
Try other strings for test, like aaa'bbb and look for error feedback. |
