CVE-2023-24332Public exploitNetwork attack vector

Authenticated command execution via unbounded time parsing

Published Feb 21, 2024 · Updated Aug 14, 2024

Stack-based buffer overflow in Tenda AC6 firmware 03.03.02.01_cn_tdc01 allows remote authenticated users to execute arbitrary commands. The PowerSaveSet handler passes the unbounded time POST value to sscanf, which writes four attacker-controlled fields into stack buffers without checking their sizes. A valid management-session cookie is required, and successful exploitation yields command execution through the router's privileged web service.
