Q-SYS Peripherals Remote Code Execution due to unauthenticated installation script

Author: Marius Creutznacher

Risk Category: High Document ID: QSYS-October-19-9009
Document Version: 1.0
 Document Status: Final

 

Description:

Q-SYS Peripherals (including Cores operating in Q-SYS Peripheral I/O mode and Q-SYS RoomSuite Peripherals) are vulnerable to an unauthenticated package install issue. This could allow an unauthenticated, remote attacker with the ability to reach the impacted device to install an arbitrary package onto an affected device. This can lead to Remote Code Execution, and potentially compromise the confidentiality, integrity or availability of the device.

Cores operating as Q-SYS Core Processors are not vulnerable to this advisory.
