Hirschmann Industrial HiVision versions prior to 06.0.07 and 07.0.03 contains an authentication bypass vulnerability in the master service that allows unauthenticated remote attackers to execute arbitrary commands with administrative privileges. Attackers can invoke exposed interface methods over the remote service to bypass authentication and achieve remote code execution on the underlying operating system.
