Local privilege escalation via installer symlink following
Published Apr 15, 2025 · Updated Apr 15, 2025
Symlink following in the macOS installer for Netskope Client allows local users to escalate file privileges during installation. The privileged postinstall script accepts the unvalidated nsinstallation path and follows a standard user's symlink, applying its privilege-changing operation to the link target. Local standard-user access and installer execution are required; affected branches are before 123.0, before 117.1.11.2310, and before 120.1.10.2306.
