Privilege-level-15 escalation via unchecked HTTP authorization
Published May 7, 2025 · Updated Feb 26, 2026
Privilege escalation in Cisco IOS Industrial Ethernet Switch Device Manager allows remote authenticated users to gain privilege level 15. The Device Manager accepts a crafted HTTP request without adequately validating whether the authenticated account is authorized for the requested privileged operation. An account at privilege level 5 or higher, including a read-only Device Manager user, can reach the flaw only when the HTTP or HTTPS server feature is enabled.
