CVE-2024-4112Network attack vector

Authenticated memory corruption via oversized list parameter

Published Apr 24, 2024 · Updated Aug 21, 2024

Stack-based buffer overflow in Tenda TX9 22.03.02.10 allows remote authenticated users to corrupt memory via a crafted list parameter. The sub_42CB94 handler for /goform/SetVirtualServerCfg processes attacker-controlled list data without enforcing a safe stack-buffer length. Administrative web-interface access is required; successful exploitation can expose or alter router data or interrupt routing.
