Open redirect vulnerability in IBM Tivoli Federated Identity Manager (TFIM) 6.1.1 before IF 15, 6.2.0 before IF 14, 6.2.1, and 6.2.2 before IF 8 and Tivoli Federated Identity Manager Business Gateway (TFIMBG) 6.1.1 before IF 15, 6.2.0 before IF 14, 6.2.1, and 6.2.2 before IF 8 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.

IBM Tivoli Federated Identity Manager (TFIM) 6.2.0 before 6.2.0.11, 6.2.1 before 6.2.1.3, and 6.2.2 before 6.2.2.2 and Tivoli Federated Identity Manager Business Gateway (TFIMBG) 6.2.0 before 6.2.0.11, 6.2.1 before 6.2.1.3, and 6.2.2 before 6.2.2.2 do not check whether an OpenID attribute is signed in the (1) SREG (aka simple registration extension) and (2) AX (aka attribute exchange extension) cases, which allows man-in-the-middle attackers to spoof OpenID provider data by inserting unsigned attributes.

IBM Tivoli Federated Identity Manager (TFIM) and Tivoli Federated Identity Manager Business Gateway (TFIMBG) 6.1.1, 6.2.0, 6.2.1, and 6.2.2 allow remote attackers to establish sessions via a crafted message that leverages (1) a signature-validation bypass for SAML messages containing unsigned elements, (2) incorrect validation of XML messages, or (3) a certificate-chain validation bypass for an XML signature element that contains the signing certificate.
