Security Bulletin: Tivoli Federated Identity Manager - Unprotected Management
Console Servlets (CVE-2012-3315) Flash (Alert)
Abstract
Document information
Tivoli Federated Identity Manager
Software version:
6.1.1, 6.2, 6.2.1
Operating system(s):
AIX, HP-UX, Linux, Solaris, Windows
Reference #:
1615770
Modified date:
2012-10-30
SUMMARY
The management console used to administer Tivoli Federated Identity
Manager contains servlets which are not all protected via a J2EE security
constraint. These servlets could be used by an unauthenticated user to
download certain resources from TFIM.
Content
VULNERABILITY DETAILS
CVE ID: CVE-2012-3315
DESCRIPTION: The Tivoli Federated Identity Manager (FIM) management console
contains Java servlets which allow downloading of certain resources from
within FIM. Two such resources are federation metadata and a web plugin
configuration template. Authentication should be required by the FIM
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's management console interface and know the
Federated Identity Manager'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 FIM could be compromised.

Security Bulletin: IBM Tivoli Federated Identity Manager OpenID: signature
validation not applied to all attributes (CVE-2012-3313)
Flash (Alert)
Document information
Tivoli Federated Identity Manager
Software version:
6.2, 6.2.1, 6.2.2
Operating system(s):
AIX, HP-UX, Linux, Solaris, Windows, z/OS
Reference #:
1615744
Modified date:
2012-10-30
Abstract
SUMMARY
An OpenID message can be modified to contain unsigned attributes that will be
accepted by a relying party because Tivoli Federated Identity Manager (TFIM)
does not check that all attributes have been signed.
Content
VULNERABILITY DETAILS
CVE: CVE-2012-3313
DESCRIPTION:
An OpenID identity provider can send attributes about a user to a relying
party via the "simple registration extension" (SREG) or "attribute exchange
extension" (AX). The response from the OpenID provider to the relying party
is transmitted via a browser redirect. The response also contains an attribute
called "openid.signed" which outlines which parameters in the response are
signed by the OpenID provider.
When TFIM receives an OpenID attribute via SREG or AX it does not check to
determine if the attribute is signed. It could therefore be possible for an
attacker either acting as a man-in-the-middle or at the browser to insert
unsigned attributes which were not sent by the OpenID provider and have the
relying party accept them. 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 confidentiality of information, but the integrity of some of the data used
in the OpenID exchange could be compromised. The consequence of this compromise
is dependent on the nature and use of the OpenID attributes by the consuming
applications.
