Unauthorized device access via weak password enforcement
Published Apr 21, 2026 · Updated Apr 21, 2026
Weak password enforcement in QNI470 firmware 6.1.1.B1 allows remote attackers on the same network to gain access by guessing credentials. The web management interface accepts account passwords without enforcing strong password requirements, leaving user accounts susceptible to password guessing and brute-force attempts. Network adjacency is required, and successful guessing grants unauthorized access to the targeted appliance; the specific account privilege level remains undisclosed.
