Root access via predictable temporary filename
Published Mar 11, 2020 · Updated Sep 17, 2024
Local privilege escalation in Palo Alto Networks PAN-OS 8.1 before 8.1.13 allows local users to gain root access on an appliance. Palo Alto Networks has not disclosed the affected process or how its temporary-file operation makes the filename predictable. Exploitation requires a restricted-shell bypass and low-privileged command execution, after which the attacker gains root on hardware or virtual appliances.
