FKIE_CVE-2021-46873

Vulnerability from fkie_nvd - Published: 2023-01-29 23:15 - Updated: 2025-03-28 16:15
Summary
WireGuard, such as WireGuard 0.5.3 on Windows, does not fully account for the possibility that an adversary might be able to set a victim's system time to a future value, e.g., because unauthenticated NTP is used. This can lead to an outcome in which one static private key becomes permanently useless.
