- n/a: version range not reported

## Description

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."

## What to do
