Until an official fix is available, restrict local access to trusted users only and monitor for suspicious activity related to backup task files. Avoid running Intego Personal Backup tasks with elevated privileges if possible.
Description
Intego Personal Backup, a macOS backup utility that allows users to create scheduled backups and bootable system clones, contains a local privilege escalation vulnerability. Backup task definitions are stored in a location writable by non-privileged users while being processed with elevated privileges. By crafting a malicious serialized task file, a local attacker can trigger arbitrary file writes to sensitive system locations, leading to privilege escalation to root.
