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.

A vulnerability was found in Palo Alto PAN-OS up to 6.1.18/7.0.18/7.1.13 (Firewall Software). It has been classified as critical. Affected is some unknown functionality of the component Web Interface. The manipulation as part of a Configuration File leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The configuration file import for applications, spyware and vulnerability objects functionality in the web interface in Palo Alto Networks PAN-OS before 6.1.19, 7.0.x before 7.0.19, and 7.1.x before 7.1.14 allows remote attackers to conduct server-side request forgery (SSRF) attacks and consequently obtain sensitive information via vectors related to parsing of external entities.

The bug was discovered 12/05/2017. The weakness was published 12/11/2017 (Website). The advisory is available at securityadvisories.paloaltonetworks.com. This vulnerability is traded as CVE-2017-15943 since 10/27/2017. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.
