CVE-2024-45367Network attack vector

Unauthenticated login via incomplete authentication process

Published Oct 3, 2024 · Updated Oct 4, 2024

Weak authentication in Optigo Networks ONS-S8 Spectra Aggregation Switch 1.3.7 and earlier allows remote attackers to log in without a password. The embedded web server uses an incomplete authentication process, but public advisories do not identify the affected request, field, or validation error. Network access to the management interface is required; successful exploitation grants an authenticated session with confidentiality and integrity impact, while availability is unaffected.
