Security Hole in Fusion Middleware 11g WebLogic Admin Server

After a little bit playing with the new Fusion Middleware 11g I found a small security hole in the WebLogic Admin Server.In order to start the WebLogic Admin Server Oracle provides you a shellscript $MW_HOME/user_projects/domains/$DOMAIN_NAME/startWebLogic.shThe first way you can use this script is in an interactive way, just execute the script and it will prompt you for the WebLogic Admin-User and his Password. But this methode is not usefull for...

Reverse Engineering with DBMS_METADATA

Today I'm coming with PL/SQL stuff, nothing with Oracle Application Server :-)At the moment I'm developing for a customer a small reverse engineering routine to capture an Oracle Database (CreateDB.sql, Tablespaces, Users, Grants aso). For this I'm using the package dbms_metadata. If you are using this package to capture e.g. all objects grants to all users, you may receive errors like this "SQL Error: ORA-31608: specified object of type OBJECT_GRANT not found". This comes up, if the user don't hold any object grants.To avoid this simply run a...
