CVE-2024-23674
The Online-Ausweis-Funktion eID scheme in the German National Identity card through 2024-02-15 allows authentication bypass by spoofing. A man-in-the-middle attacker can assume a victim's identify for access to government, medical, and financial resources, and can also extract personal data from the card, aka the "sPACE (Spoofing Password Authenticated Connection Establishment)" issue. This occurs because of a combination of factors, such as insecure PIN entry (for basic readers) and eid:// deeplinking. The victim must be using a modified eID kernel, which may occur if the victim is tricked into installing a fake version of an official app. NOTE: the BSI position is "ensuring a secure operational environment at the client side is an obligation of the ID card owner."

Esto ocurre debido a una combinación de factores, como la entrada insegura del PIN (para lectores básicos) y los enlaces profundos eid://. La víctima debe estar utilizando un kernel de eID modificado, lo que puede ocurrir si se engaña a la víctima para que instale una versión falsa de una aplicación oficial. NOTA: la posición de BSI es \"garantizar un entorno operativo seguro en el lado del cliente es una obligación del propietario de la tarjeta de identificación\"."
