Description
epa4all-client is the Java Client for epa4all / ePA 3.0 in the Telematik Infrastruktur. Prior to 1.2.1, in SignedPublicKeysTrustValidatorImpl.isTrusted(), the ECDSA signature verification at line 45 discards the boolean return value of Signature.verify(). The method performs certificate chain validation, OCSP check, and signature algorithm setup, but never checks whether the signature actually matches. For any structurally valid signature, it returns true. This vulnerability is fixed in 1.2.1.

Title: epa4all-client de oviva-ag, Description: epa4all-client es el cliente Java para epa4all / ePA 3.0 en la Telematik Infrastruktur. Antes de 1.2.1, en SignedPublicKeysTrustValidatorImpl.isTrusted(), la verificación de firma ECDSA en la línea 45 descarta el valor de retorno booleano de Signature.verify(). El método realiza la validación de la cadena de certificados, la comprobación OCSP y la configuración del algoritmo de firma, pero nunca comprueba si la firma realmente coincide. Para cualquier firma estructuralmente válida, devuelve true. Esta vulnerabilidad se corrige en 1.2.1.
