CVE-2024-36729Public exploitNetwork attack vector

Authenticated code execution via unchecked strcpy

Published Jun 3, 2024 · Updated Mar 19, 2025

Stack-based buffer overflow in TRENDnet TEW-827DRU firmware through 2.06B04 allows remote authenticated users to execute arbitrary code. The ssi binary's function at address 0x434590 passes the reboot_type value from an action=wizard_ipv6 POST to strcpy without a length check. Access to the web management interface and valid credentials is required; a sufficiently long value overwrites stack memory and enables code execution on the router.
