CVE-2025-65002Network attack vector

Authenticated privilege escalation via 16-character username

Published Nov 12, 2025 · Updated Nov 12, 2025

Incorrect authorization in Fujitsu iRMC S6 on M5 before 1.37S allows remote authenticated users to exceed assigned privileges. The Redfish/WebUI authorization path grants access beyond the configured non-Administrator role when the username is exactly 16 characters. Exploitation requires a Redfish-enabled, non-Administrator account with that username length, enabling unauthorized WebUI or Redfish API operations.
