CVE-2021-3196: Hitachi Id Bravura Security Fabric

High severity, CVSS 8.8. EPSS: 1% chance of exploitation in the next 30 days.

An issue was discovered in Hitachi ID Bravura Security Fabric 11.0.0 through 11.1.3, 12.0.0 through 12.0.2, and 12.1.0. When using federated identity management (authenticating via SAML through a third-party identity provider), an attacker can inject additional data into a signed SAML response being transmitted to the service provider (ID Bravura Security Fabric). The application successfully validates the signed values but uses the unsigned malicious values. An attacker with lower-privilege access to the application can inject the username of a high-privilege user to impersonate that user.

Affected products

• Hitachi Id Bravura Security Fabric: from 11.0.0, up to and including 11.1.3; from 12.0.0, up to and including 12.0.2; version 12.1.0 only
