CVE-2026-23999
Publiée le 2026-02-26 · Dernière modification le 2026-06-17
Les versions du logiciel de gestion de flotte antérieures à la 4.80.1 utilisent un horodatage prévisible pour générer les codes PIN de verrouillage et d'effacement des appareils. Un attaquant ayant la possession physique d'un appareil verrouillé pourrait théoriquement deviner le code PIN s'il sait approximativement quand la commande de verrouillage a été émise. Comme le système d'exploitation impose une limitation du nombre de tentatives de saisie du code PIN, cette opération est difficile à réaliser et ne peut être effectuée à distance.
DÉTAIL DU VECTEUR CVSS
RÉFÉRENCES
Description officielle du NVD (en anglais)
Fleet is open source device management software. In versions prior to 4.80.1, Fleet generated device lock and wipe PINs using a predictable algorithm based solely on the current Unix timestamp. Because no secret key or additional entropy was used, the resulting PIN could potentially be derived if the approximate time the device was locked is known. Fleet’s device lock and wipe commands generate a 6-digit PIN that is displayed to administrators for unlocking a device. In affected versions, this PIN was deterministically derived from the current timestamp. An attacker with physical possession of a locked device and knowledge of the approximate time the lock command was issued could theoretically predict the correct PIN within a limited search window. However, successful exploitation is constrained by multiple factors: Physical access to the device is required, the approximate lock time must be known, the operating system enforces rate limiting on PIN entry attempts, attempts would need to be spread over, and device wipe operations would typically complete before sufficient attempts could be made. As a result, this issue does not allow remote exploitation, fleet-wide compromise, or bypass of Fleet authentication controls. Version 4.80.1 contains a patch. No known workarounds are available.
