CVE-2024-0336Network attack vector

Access-control bypass via missing critical-function authentication

Published Jun 3, 2024 · Updated Jun 3, 2026

Missing authentication in EMTA Grup PDKS 3.04 before 20240603 allows remote authenticated users to bypass critical access controls. Public sources do not identify the affected endpoint, critical function, or access-control decision that omits authentication. Network access and low privileges are required, and successful exploitation permits access at security levels unavailable to the account.
