If you have read on dba_users then you potentially have access to a
means of connecting as any user.  The technique involves understanding
how Oracle creates users via import.  This is a security hole opened up
by select any table or select catalog privilege.

Ron,

I read the article and see where it says not to grant it, but I do not
see anything about it "subverting" anything.  Rather it seems to be a
concern that this may be more privilege than is needed and so violates
the "least privilege principle".   I wouldn't want to generally grant
this or any "ANY" privilege, but I still do not see a specific risk to
granting admins/consultant admins this level of view privilege.  Are you
able to use this to 1) see actual company data and not just the
dictionary views or 2) update anything?  If not, what is the specific
concern?  What am I missing?

Thanks!

Because it subverts a security setting.  See

While I totally agree that sys and system don't need to be given to
anyone other than the primary DBA and then sealed in an envelope hidden
away in a safe, I am not so clear on why granting select any dictionary
is as big a concern.  As far as I know, this only allows view access to
the data dictionary, which pretty much anyone doing any tuning or
monitoring probably needs.  Even OEM assumes a non-sys/non-system
account with this level of privilege which is used for monitoring.  Is
there a specific reason not to let people have select any dictionary? =20

Just curious.

Assuming that you made the request of the client using the same tone as
here, I'm not surprised.  Why do you need an account with such
priviledges?  In general NO one outside of the DBA group here has access
to SYS or SYSTEM, including internal folks.
