Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the sysreboot function. The vulnerability is caused by insufficient filtering of the config, act, pathN, and valueN fields before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.
