What is CVE-2024-23674?
CVE-2024-23674 is a critical authentication bypass vulnerability in n/a, published on 15 Feb 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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."
Weakness: CWE-290
