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 has been found in Cisco TelePresence X8.7.2/X8.8.3 (Unified Communication Software) and classified as critical. This vulnerability affects an unknown code block. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability.

The bug was discovered 10/27/2016. The weakness was released 12/07/2016 by Micha Borrmann with SYSS as cisco-sa-20161207-expressway as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability was named CVE-2016-9207 since 11/06/2016. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available. The advisory points out:

The vulnerability is due to insufficient access control for TCP traffic passed through the Cisco Expressway. An attacker could exploit this vulnerability by sending a crafted URL through the Cisco Expressway. An exploit could allow the attacker to enumerate hosts and services of arbitrary hosts, as well as degrade performance through the Cisco Expressway.

A public exploit has been developed in URL and been published 1 weeks after the advisory. It is possible to download the exploit at seclists.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 41 days. During that time the estimated underground price was around $5k-$25k. The code used by the exploit is:

curl --include https://jabberguest.company.com/127.0.0.1:22/jabberc/rest/calls/index.txt

Upgrading eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
