Hi
I would recommend first trying to get the source code
if possible : http://x.y.z.a/dbs.inc but I guess it
won't work it should be a secure web server :)
Anyways depending on the Oracle version you can easily
own it, you just need to inject a function and exploit
some known sql injection in Oracle or depending on
permissions you can just run any commands.
http://x.y.z.a/item.php?Id=length(dbms_xmlquery.getXml('your
favority sql injection exploit here or any command'))
Look at :
