What to do

AI-suggested

Mitigation should focus on multiple layers: First, users must be educated to avoid installing unofficial or modified eID applications and to verify app authenticity through official channels. Organizations and the BSI should enhance awareness campaigns emphasizing the importance of maintaining a secure operational environment on client devices. Deployment of endpoint security solutions capable of detecting unauthorized modifications to the eID kernel or suspicious app installations is recommended. Developers should consider implementing stronger PIN entry protections, such as hardware-based secure PIN entry or multi-factor authentication mechanisms that do not rely solely on PINs. The BSI and relevant authorities should expedite development and release of official patches or updated eID app versions that address deeplinking vulnerabilities and enforce integrity checks on the eID kernel. Additionally, monitoring for phishing or social engineering campaigns targeting eID users can help reduce the risk of kernel compromise. Organizations relying on eID authentication should implement anomaly detection and additional verification steps for high-risk transactions. Finally, users should be advised to regularly update their devices and apps to incorporate any forthcoming security improvements.

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."
