CVE-2023-38032Network attack vector

Authenticated command execution via unfiltered AiProtection parameters

Published Sep 7, 2023 · Updated Sep 26, 2024

OS command injection in the AiProtection function in ASUS RT-AC86U 3.0.0.4.386.51529 allows remote authenticated users to execute commands. The function passes special-character-bearing parameters to an operating-system command without sufficient filtering. Regular user privileges and network access to the router are required; injected commands can alter device state, interrupt the system, or terminate services.
