CVE-2024-45407Network attack vector

Client authorization bypass via premature certificate persistence

Published Sep 10, 2024 · Updated Sep 10, 2024

Authentication bypass in LizardByte Sunshine affected pre-release builds allows man-in-the-middle attackers to gain client access. The pairing handler adds a forged request's certificate to named_devices before PIN validation finishes, so failed pairing can persist it as trusted. Exploitation requires interception of a legitimate pairing attempt and the user to enter the original PIN; the attacker then connects with the persisted certificate.
