CVE-2025-52906Network attack vector

Unauthenticated command execution via unsanitized agentName

Published Sep 24, 2025 · Updated Sep 24, 2025

OS command injection in TOTOLINK X6000R through V9.4.0cu.1360_B20241207 allows remote attackers to execute arbitrary commands. The setEasyMeshAgentCfg handler at /cgi-bin/cstecgi.cgi passes the unsanitized agentName parameter into an operating-system command. Remote attackers who can reach the router web interface can run commands with the web server process and obtain root-level control of device traffic and persistence.
