CVE-2024-0799Known exploitationPublic exploitNetwork attack vector

Authentication bypass via omitted password parameter

Published Mar 13, 2024 · Updated Dec 16, 2025

Authentication bypass in Arcserve Unified Data Protection 8.1 and 9.2 allows remote attackers to access the UDP Console without credentials. EdgeLoginServiceImpl.doLogin treats an omitted password as a request to retrieve the application's UUID and validates that UUID instead of the supplied user. A passwordless POST to /management/wizardLogin therefore creates an authenticated session able to perform Console tasks that normally require login.
