CVE-2025-7613Public exploitNetwork attack vector

Authenticated command execution via unsanitized ip parameter

Published Jul 14, 2025 · Updated Jul 14, 2025

Command injection in TOTOLINK T6 4.1.5cu.748 allows remote authenticated users to execute operating system commands via the ip parameter. CloudSrvVersionCheck passes the request's ip value through safe_cs_pub to tcpcheck_net, which concatenates it into a tcpcheck command executed by system. Low-privilege network access to the HTTP POST handler is required, after which injected shell metacharacters permit arbitrary command execution on the router.
