CVE-2022-1984

Local privilege escalation via unsafe deserialization

Published Jul 19, 2022 · Updated Aug 3, 2024

Unsafe deserialization in HYPR Passwordless for Windows before 7.2 allows local users to elevate privileges with a malicious serialized payload. HYPR has not published the Windows component that accepts the payload or how its deserializer processes attacker-controlled objects. A local low-privileged account is required, and successful exploitation raises that account's privileges on the Windows host.
