PAN-SA-2016-0015 Cron local privilege escalation
Description
Palo Alto Networks firewalls use the cron infrastructure to perform household system cleanup at regular intervals. Due to an error in user input normalization, a file locally created by an end user and placed in a specific directory could be executed in a higher privilege context (Ref. 93612).
Because no shell access is available to end-users, exploitation of this issue is unlikely.
This issue affects PAN-OS 5.0.18 and prior; PAN-OS 5.1.11 and prior; PAN-OS 6.0.13 and prior; PAN-OS 6.1.11 and prior; PAN-OS 7.0.6 and prior; PAN-OS 7.1.1 and prior
