Hey

You may have heard about the Sql injection that was in the last10.php in vbulletin, and the code injection is as bellow:

Code:
last10.php?ftitle=%20WHERE%20userid=0%20UNION%20SELECT%20null, userid, password, null, null, null, null, null, null%20FROM%20user%20WHERE%20usergroupid=6%20LIMIT%201/*


My question is, can the UNION SELECTE above be replace with INSERT INTO?

if yes, how the code show be? I tried replacing UNION SELECT with INSERT TO, but it didn't work, any idea?

Thanks in advance!

If you have sql injection in "SELECT ... UNION ... " clause, then you can't use "INSERT INTO" in any way, if database is MySql. M$SQL and PostgreSql databases will let you concatenate additional queries by adding semicolon, but MySql/PHP platform does not support this.
There can be possibilities to use "INTO OUTFILE" construction in some cases though ... Smile

I guess that it is not possible not only for INSERT INTO, but UPDATE and any other mysql commands, right?

is there any trick to insert a new line in the mysql database, or shall I give up into that?

Thanks alot for your help Smile

Yes, in most cases, you just can't actively manipulate (UPDATE or INSERT) mysql database content, when you have found sql injection in SELECT clause.
