This blog post dives into the most common classes of macOS Local Privilege Escalation vulnerabilities, from insecure XPC communications and time-of-check to time-of-use (TOCTOU) Race Conditions to a range of implementation and configuration oversights. We will explore how attackers can exploit these weaknesses to escalate privileges, and highlight real-world examples to illustrate recurring patterns. This post ends the series on Intego products on macOS by revealing vulnerabilities that can lead to Local Privilege Escalation, as well as a surprise bonus.
