ISC BIND 9.8.1-P1 Smoothed Round Trip Time Algorithm DNS authentication spoofing

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 ISC BIND 9.8.1-P1 (Domain Name Software). It has been rated as critical. Affected by this issue is an unknown part of the component Smoothed Round Trip Time Algorithm. The manipulation with an unknown input leads to a authentication spoofing vulnerability (DNS). Using CWE to declare the problem leads to CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. Impacted is confidentiality, integrity, and availability.

The weakness was shared 05/08/2014 by Roee Hay, Jonathan Kalechstein and Gabi Nakibly as Subverting BIND's SRTT Algorithm Derandomizing NS Selection as confirmed presentation (USENIX Workshop WOOT '13). The advisory is shared for download at isc.org. The presentation contains:

The attack reduces the time and effort required to successfully poison BIND's cache.
The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 04/02/2019).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at SecurityTracker (ID 1030211†). 0b4af6cdc2f0c5998459-c0245c5c937c5dedcca3f1764ecc9b2f.r43.cf2.rackcdn.com is providing further details.
