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 ... |

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 |

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. |
