CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Palo Alto PAN-OS up to 5.0.18/5.1.11/6.0.13/6.1.11/7.0.7 (Firewall Software) and classified as critical. Affected by this issue is the function root_reboot. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Palo Alto Networks PAN-OS before 5.0.19, 5.1.x before 5.1.12, 6.0.x before 6.0.14, 6.1.x before 6.1.12, and 7.0.x before 7.0.8 might allow local users to gain privileges by leveraging improper sanitization of the root_reboot local invocation.

The weakness was presented 07/13/2016 by Kasif Dekel as PAN-SA-2016-0012 / 92293 as confirmed advisory (Website). The advisory is shared for download at securityadvisories.paloaltonetworks.com. This vulnerability is handled as CVE-2016-1712 since 01/12/2016. The exploitation is known to be easy. The attack needs to be approached locally. No form of authentication is required for exploitation. There are known technical details, but no exploit is available. The advisory points out:

Palo Alto Networks firewalls do not properly sanitize the root_reboot local invocation which can potentially allow executing code with higher privileges

The vulnerability scanner Nessus provides a plugin with the ID 93125 (Palo Alto Networks PAN-OS 5.0.x < 5.0.19 / 5.1.x < 5.1.12 / 6.0.x < 6.0.14 / 6.1.x < 6.1.12 / 7.0.x < 7.0.8 Privilege Escalation (PAN-SA-2016-0012)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Palo Alto Local Security Checks and running in the context c. The advisory illustrates:

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.

Upgrading to version 5.0.19, 5.1.12, 6.0.14, 6.1.12 or 7.0.8 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (93125) and SecurityTracker (ID 1036326†). VulDB is the best source for vulnerability data and more expert information about this specific topic.
