OS command injection in QNAP QTS, Multimedia Console, and Media Streaming add-on allows remote attackers to execute commands over a network. QNAP has not published the affected component, accepted input, or unsafe operation that reaches the command interpreter. The published assessment requires no authentication or user interaction, while successful exploitation grants arbitrary command execution.
