VULNERABILITY DETAILS

CVE ID: CVE-2012-3315

DESCRIPTION:
The Tivoli Federated Identity Manager Business Gateway (TFIMBG) management console contains Java servlets which allow downloading of certain resources from within TFIMBG. Two such resources are federation metadata and a web plugin configuration template. Authentication should be required by the TFIMBG management console in order to access to these resources, but it is not.

In order to access these resources, an attacker must have network access to the Federated Identity Manager Business Gateway’s management console interface and know the Federated Identity Manager Business Gateway’s domain name and the URLs for the servlets they wish to access. In the case of accessing federation metadata, an attacker must also know the unique identifier (uuid) of a federation. An attacker could then build up the appropriate URL parameters and make a request without an authenticated session to retrieve the resource.
The attack does not require local network access nor does it require authentication, but specialized knowledge and techniques are required. An exploit will not impact accessibility of system resources or the integrity of information, but the confidentiality of some of the data used by TFIMBG could be compromised.
