Local Privilege Escalation

Palo Alto Networks firewalls do not properly validate certain environment variables which can potentially allow executing code with higher privileges (Ref # PAN-61104/100499/CVE-2016-9151)
A potential attacker with local shell access could manipulate arbitrary environment variables which could result in a process running with higher privileges.
This issue affects PAN-OS 5.0.19 and earlier; PAN-OS 5.1.12 and earlier; PAN-OS 6.0.14 and earlier; PAN-OS 6.1.14 and earlier; PAN-OS 7.0.10 and earlier; PAN-OS 7.1.5 and earlier

Work around:
Exploitation of this privilege escalation is restricted to local users. Potential attackers would have to first obtain a shell on the device before they could attempt to escalate privileges through this vulnerability.
