What is CVE-2025-70329?

The TOTOLink X5000R router version 9.1.0cu_2415_B20250515 is susceptible to an OS command injection flaw in the setIptvCfg handler of its /usr/sbin/lighttpd service. This vulnerability arises from inadequate validation of parameters such as vlanVidLan1 during command execution, enabling authenticated attackers to inject shell metacharacters. This exploitation could lead to the unauthorized execution of arbitrary commands with root privileges, potentially compromising the entire device.
