CVE-2022-24584

CWE-863Published: May 11, 2022· Updated: Jun 17, 2026

6.5
CVSS v3.1

Official Description

Incorrect access control in Yubico OTP functionality of the YubiKey hardware tokens along with the Yubico OTP validation server. The Yubico OTP supposedly creates hardware bound second factor credentials. When a user reprograms the OTP functionality by "writing" it on a token using the Yubico Personalization Tool, they can then upload the new configuration to Yubicos OTP validation servers. NOTE: the vendor disputes this because there is no way for a YubiKey device to prevent a user from deciding that a secret value, which is imported into the device, should also be stored elsewhere

Technical Analysis

CVE-2022-24584 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
