CVE-2023-48802Public exploitNetwork attack vector

Unauthenticated command execution via unsafe front-end fields

Published Nov 30, 2023 · Updated Jun 5, 2025

OS command injection in TOTOLINK X6000R 9.4.0cu.852_B20230719 allows remote attackers to execute arbitrary system commands. The shttpd sub_4119A0 function obtains front-end fields through Uci_Set_Str and passes the resulting values to CsteSystem without command neutralization. Network access to the router's front-end input path is sufficient, and successful exploitation grants command execution with the service's privileges.
