CVE-2025-52046Public exploitNetwork attack vector

Unauthenticated command execution via Wi-Fi ACL parameters

Published Jul 17, 2025 · Updated Sep 15, 2025

Command injection in TOTOLINK A3300R 17.0.0cu.596_B20250515 allows remote attackers to execute arbitrary commands via crafted requests. In shttp, sub_4197C0 concatenates the mac and desc parameters with snprintf, and wificonf_add_by_key passes the result to csteSystem without neutralizing command syntax. The setWiFiAclRules request requires no authentication and executes commands on the router; persistence and internet exposure are not established.
