Oracle WebCenter is a platform for building web applications, web portals and
collaboration web sites. It is owned and developed by Oracle targeting the enterprise portal market.
We have discovered an information exposure vulnerability in the Oracle WebCenter portal component in Oracle Fusion Middleware (versions 220.127.116.11 and 18.104.22.168) that leads to disclosure of user information.
Specifically, an unauthenticated attacker can retrieve all information related
to the users of the platform via a default user account of the Oracle WebCenter installation.
This includes usernames, emails, phone numbers and files linked to the
The attack can be achieved via the following steps:

2. The attacker has now gained unauthenticated access to the Oracle WebCenter backend interface
as the default user “weblogic”. From the backend interface the attacker may then
navigate to the “Documents” tab.
3. In the “Filter” field the attacker selects “Advanced” as illustrated
in the following screenshot.
4. The attacker then clicks the binoculars icon next to the “Created By” field.
5. In the search field the attacker enters “*” and retrieves the complete list
of the system’s usernames along with emails and phone numbers, as shown in the
Moreover, once the list of all valid usernames has been retrieved,
an attacker will be able to gain unauthenticated read access to files linked to each user profile
on the Oracle WebCenter installation via the following URL (edited for readability):
