Description
epa4all-client is the Java Client for epa4all / ePA 3.0 in the Telematik Infrastruktur. Prior to 1.2.2, an attacker who can MITM the TLS connection between the client and the IDP (within the TI network) can substitute a forged discovery document. The forged document redirects uri_puk_idp_enc and uri_puk_idp_sig to attacker-controlled URLs. The client then encrypts the SMC-B-signed challenge response to the attacker's encryption key and POSTs it to the attacker's auth endpoint. This captures the signed authentication material. This vulnerability is fixed in 1.2.2.

Title: epa4all-client, Description: epa4all-client es el Cliente Java para epa4all / ePA 3.0 en la Telematik Infrastruktur. Anterior a la 1.2.2, un atacante que puede realizar un MitM a la conexión TLS entre el cliente y el IDP (dentro de la red TI) puede sustituir un documento de descubrimiento falsificado. El documento falsificado redirige uri_puk_idp_enc y uri_puk_idp_sig a URLs controladas por el atacante. El cliente entonces cifra la respuesta al desafío firmada con SMC-B con la clave de cifrado del atacante y la envía mediante POST al endpoint de autenticación del atacante. Esto captura el material de autenticación firmado. Esta vulnerabilidad está corregida en la versión 1.2.2.
