Re: Domain Account used for IIS6 Anonymous Account Risks?

Well the most obvious risk is that IIS knows the password for the xyzweb account. If someone can get IIS to execute arbitrary code (e.g. by uploading some of their own webpages) then IIS can connect to serverB using the domain\xyzweb account, and that account has full privileges on serverB

Here is the situation:

Two servers: ServerA is a IIS6 server
ServerB is a application server with a DB

ServerA sits in public IP space, ServerB is in private with an access list
on a router allowing the two to communicate.


ServerA is using a domain user account say “xyzweb” for the IIS Anonymous
user and has no elevated rights on this server.

ServerB has this same domain account “xyzweb” in its local admin group.


When joe-public accesses ServerA the anon account “xyzweb” accesses data
records from ServerB. Now this access is being done with com objects or
something of the sort.

Knowing all of this and knowing that as far as the application vendor, this
is the only way it will work….lets discuss risks:

Any comments are most appreciated.
