CVE-2025-59371Network attack vector

Authenticated device access via insufficiently random values

Published Nov 25, 2025 · Updated Feb 26, 2026

Authentication bypass in ASUS Router firmware 3.0.0.4_386, 3.0.0.4_388, and 3.0.0.6_102 allows remote authenticated users to access devices. ASUS maps the flaw to insufficiently random values in the IFTTT integration but has not disclosed which value is predictable or how it bypasses authentication. Exploitation requires high privileges and additional attack conditions; Wi-Fi 7 models are unaffected, and successful access affects device data and operation.
