Credential exposure via injected UNC disk reference
Published Dec 13, 2023 · Updated Aug 2, 2024
UNC reference injection in PRIMX CRYHOD for Windows before 2023.5 allows physically proximate attackers to obtain user credentials. When a compromised encrypted disk is opened, CRYHOD follows an attacker-added UNC reference, initiating outbound network access and an authentication request. The attacker must alter a disk and have it opened on a Windows host; the resulting exchange can disclose user credentials and enable use of that user's privileges.
