Root escalation via ntpServer PATH hijacking
Published Aug 5, 2022 · Updated Aug 3, 2024
Local privilege escalation in VMware Workspace ONE Access, Identity Manager, and vRealize Automation allows local users to gain root. The sudo-authorized ntpServer.hzn script invokes the missing sntp program by name, allowing a low-privileged user to prepend a writable directory to PATH and supply a root-run replacement. Low-privileged code execution on an affected appliance is required, and successful exploitation grants arbitrary code execution as root.
