CVE-2022-37940Network attack vector

Unauthenticated URL redirection via injected Host header

Published Mar 15, 2023 · Updated Feb 27, 2025

Open redirect in HPE FlexFabric 5700 Switch Series before R2432P61 allows remote attackers to redirect users via crafted Host headers. The HTTP host-header handling accepts an attacker-controlled Host value when generating a redirect, but HPE has not disclosed the affected interface or code path. No authentication is required, and the documented consequence is limited to host-header injection and redirection.
