Patch availableIBM 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.

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
An attacker operating through the affected interface may attempt exploitation when the stated preconditions are met. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-20: Improper Input Validation. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
