CVE-2023-52028Public exploitNetwork attack vector

Unauthenticated command execution via constructed traceroute command

Published Jan 11, 2024 · Updated Jun 20, 2025

OS command injection in TOTOlink A3700R 9.1.2u.5822_B20200513 allows remote attackers to execute arbitrary commands over the network. The setTracerouteCfg function incorporates insufficiently filtered special characters into a constructed operating-system command. No authentication or user interaction is required, and successful exploitation runs commands with the router web service's privileges.
