Mysql Information schema column_privileges empty

Information Security Asked by Bob on December 1, 2020

I can try some SQL-injection against a ad-hoc damn web application in my virtual enviroment for educational purpose.
In one of these I obtain the table column_privileges (of Mysql Information schema) empty, I retrive the table but the fiels are empty. Is it possible that this table is empty or I have not the privileges to see it? Is there some test to obtain the confirm that I have not the privilege to see this table? In the case it is really empty, does this imply some important consideration?

One Answer

It is no possible see information about database objects for which you don't have permissions. An empty information_schema table suggests a permissions issue for the user you are using to connect to the server.
