OS command injection in ChangingTec ServiSign allows remote attackers to execute arbitrary system commands through a malicious website. The component insufficiently filters special characters in its connection response parameter before passing the value into command execution. Exploitation requires a ServiSign user to visit attacker-controlled content; successful injection permits arbitrary system operations or service interruption.
