CVE-2022-2662Network attack vector

Unauthenticated user-level access via undisclosed authentication bypass

Published Aug 16, 2022 · Updated Apr 16, 2025

Improper authentication in Sequi PortBloque S all versions allows remote attackers to gain user-level access through a network interface. Public advisories do not identify the affected authentication handler or explain how untrusted input bypasses its checks. The device interface must be network-reachable, and exploitation grants only the ordinary-user functions documented by the record, not administrator privileges.
