CVE-2023-4669Network attack vector

Unauthenticated system access via crafted request

Published Sep 14, 2023 · Updated May 21, 2026

Authentication bypass in Exagate SYSGuard 3001 before 3.2.20.0 allows remote attackers to gain unauthorized system access via a crafted request. Public advisories do not disclose which assumed-immutable datum is trusted or which request handler performs the faulty authentication decision. Network access without credentials is sufficient, and successful exploitation permits control that compromises system data and operation.
